Growing tangerine trees in your backyard or orchard can be an incredibly rewarding experience, offering fragrant blossoms and delicious, easy-to-peel fruit. However, maximizing fruit production requires more than just proper watering and fertilization. One of the most effective yet often overlooked strategies for improving tangerine yields is companion planting with pollinator-attracting flowers. By strategically planting the right companion flowers around your tangerine trees, you can create a thriving ecosystem that supports robust pollination, natural pest control, and overall tree health.
Understanding Tangerine Tree Pollination
Most tangerine trees are self-pollinating, meaning they have perfect flowers with both male and female organs on the same blossom. This characteristic makes them easier to grow than many other fruit trees that require a separate pollination partner. However, self-pollination doesn't mean that tangerines don't benefit from pollinator assistance.
Cross-pollinated tangerines usually produce more and larger fruit than trees left to pollinate themselves. Honeybees are the primary pollinators for tangerines, carrying pollen from the flowers of one tree to another, ensuring cross-pollination and good crops. Even though tangerine trees can technically pollinate themselves, the presence of active pollinators significantly improves fruit set, size, and overall yield.
It's important to note that some tangerine varieties are self-sterile and require another tree to pollinate them, including Robinson, Sunburst, and the Minneola and Orlando tangerine-grapefruit crosses. For these varieties, attracting pollinators becomes even more critical for successful fruit production.
Why Companion Flowers Are Essential for Tangerine Trees
Companion planting is an ancient agricultural practice that involves growing different plants together for mutual benefit. Plants with complementary characteristics can help each other by naturally repelling pests, attracting pollinators, providing shade, suppressing weeds, or adding nutrients to the soil.
For tangerine trees specifically, companion flowers serve several vital functions. Wildflowers and other companion plants attract pollinators such as bees, butterflies and hummingbirds, and your tree will pollinate far more efficiently if it gets help from those naturally occurring pollinators. This is particularly important during the spring blooming period when tangerine trees produce their fragrant white flowers.
Companion planting attracts pollinators, deters common pests, supplies nutrients, improves productivity of fruiting trees, and helps ensure that citrus trees produce a plentiful crop. Beyond pollination, the right companion plants create a biodiverse ecosystem that supports beneficial insects, improves soil health, and reduces the need for chemical interventions.
The Science Behind Pollinator Attraction
Bees, butterflies, and hoverflies are critical for pollination and general garden health, and insect visits help fruit set and overall orchard biodiversity. When you plant flowers that bloom simultaneously with your tangerine trees, you create a pollinator highway that brings these beneficial insects directly to your citrus blossoms.
The visual appeal of colorful flowers combined with nectar availability makes your orchard irresistible to pollinators. The wildflower's variety of colors is visually appealing to pollinators and provides a good mix of nectar they can use as energy. This increased pollinator activity translates directly into better fruit set and larger harvests.
Best Companion Flowers for Attracting Pollinators to Tangerine Trees
Selecting the right companion flowers is crucial for creating an effective pollinator garden around your tangerine trees. The best choices are those that bloom during the same period as citrus trees, provide abundant nectar and pollen, and thrive in similar growing conditions.
Lavender
Lavender is one of the most popular companion plants for citrus trees, and for good reason. Its fragrant purple blooms are highly attractive to bees and butterflies, creating a constant buzz of activity in your orchard. Lavender has relatively short roots, which is good since deeper roots can compete with the citrus tree's shallow roots, and it prefers hot and dry conditions.
Lavender blooms for an extended period during the warm months, providing a consistent nectar source for pollinators. The aromatic oils in lavender also have natural pest-repelling properties, adding an extra layer of protection for your tangerine trees. Plant lavender in clusters around the perimeter of your citrus trees, ensuring it receives full sun and well-drained soil.
Marigolds
Marigolds are an excellent companion crop for almost any plant because their smell drives away so many bad insects. These bright, cheerful flowers serve a dual purpose in the tangerine orchard: they attract beneficial pollinators while simultaneously repelling harmful pests.
Marigolds are really good for protecting citrus trees against nematodes, and can act not only as nematode repellers but also destroy them thanks to a naturally occurring allelochemical in their roots known as α-terthienyl. This makes marigolds particularly valuable in areas where soil-borne pests are a concern.
Marigolds are incredibly easy to grow, thriving in full sun and well-drained soil—conditions that align perfectly with tangerine tree requirements. Their vibrant orange, yellow, and red blooms add visual appeal to your orchard while working hard to support tree health.
Borage (Starflower)
Borage, also known as starflower, is a low maintenance plant that prefers full or part sun, and will appeal to bees, butterflies, and hummingbirds. This annual herb produces beautiful star-shaped blue flowers that are particularly attractive to bees, making it an excellent choice for improving pollination rates.
Borage offers additional benefits beyond pollinator attraction. Even predatory insects find borage inviting, which helps establish a natural pest control system in your orchard. The plant is also edible, with both leaves and flowers being safe for human consumption, adding culinary value to your garden.
Borage is known for its ability to improve soil health through its deep taproot, which brings up nutrients from lower soil layers. When the plant dies back, these nutrients become available to shallow-rooted plants like tangerine trees.
Wildflowers
Wildflowers are one of the best companion plants for citrus trees, mainly because they attract a variety of beneficial insects, such as pollinators including bees, butterflies, and hummingbirds. The term "wildflowers" encompasses a wide range of native and naturalized flowering plants that thrive with minimal maintenance.
Some great choices to go with your citrus tree are echinacea (also known as coneflower), Queen Anne's Lace, bee balm, and various types of daisies (including Black-Eyed Susans). These flowers provide diverse bloom times, ensuring that pollinators have a reason to visit your orchard throughout the growing season.
Wildflowers are particularly valuable because they're often native to your geographic location, making them well-adapted to local climate conditions and requiring less water and maintenance than exotic species. They also support native pollinator populations, contributing to broader ecosystem health.
Sunflowers
Sunflowers are pollinator magnets, with their large, bright blooms providing abundant nectar and pollen for a wide variety of insects. The tall stature of sunflowers can provide some afternoon shade for young tangerine trees in extremely hot climates, though care should be taken not to block too much sunlight from the citrus canopy.
Sunflowers are particularly effective at attracting native bees, which are often more efficient pollinators than honeybees for certain crops. Their seeds also attract beneficial birds that help control insect pests in the orchard. Plant sunflowers on the north or east side of tangerine trees to avoid excessive shading.
Cosmos
Cosmos are easy-to-grow annual flowers that produce abundant blooms in shades of pink, white, purple, and orange. Their open, daisy-like flowers are easily accessible to a wide range of pollinators, including small native bees and butterflies. Cosmos bloom prolifically from summer through fall, extending the pollinator season well beyond the spring citrus bloom period.
These flowers are drought-tolerant once established and thrive in the same full-sun conditions preferred by tangerine trees. Cosmos also self-seed readily, creating a self-sustaining pollinator garden with minimal effort in subsequent years.
Calendula
Calendula, a familiar annual also called marigold, will perform a dual purpose by attracting both pollinating and predatory insects. These cheerful orange and yellow flowers bloom for extended periods and are particularly attractive to hoverflies, which are excellent pollinators and whose larvae feed on aphids.
Calendula is also known for its medicinal properties and edible flowers, making it a multi-functional addition to your orchard. The plant thrives in full sun to partial shade and tolerates a wide range of soil conditions, making it adaptable to various orchard environments.
Yarrow
Yarrow's bold color palette of red, purple, orange, pink and white is enticing to insects. This perennial herb produces flat-topped clusters of tiny flowers that are particularly attractive to beneficial insects like ladybugs, lacewings, and parasitic wasps.
Yarrow is drought-tolerant and thrives in poor soil, making it an excellent low-maintenance companion for tangerine trees. Blooming at the same time is important in that pollinators will arrive as the trees are putting on buds, and yarrow's spring to summer bloom period aligns well with citrus flowering.
Comfrey
Comfrey is one of the most popular companion flowers at the moment because not only can it be used to attract pollinators but it grows incredibly fast and tall—eventually falling over and making a great mulch for other plants. This perennial herb produces bell-shaped purple, pink, or white flowers that are highly attractive to bees.
Comfrey is known as a "dynamic accumulator," meaning its deep roots mine nutrients from deep in the soil and bring them to the surface. When comfrey leaves are cut and used as mulch around tangerine trees, they release these nutrients, particularly potassium, which is essential for fruit development. While comfrey doesn't have any foes, it can grow and spread aggressively, so many gardeners prefer to grow Russian comfrey due to it having sterile seeds.
Nasturtiums
Nasturtiums are great companions for citrus trees because they attract pollinators and attract aphids away from the tree. These colorful, edible flowers serve as a "trap crop," drawing aphids and other pests to themselves and away from your valuable tangerine trees.
Nasturtiums are incredibly easy to grow, thriving in poor soil and requiring minimal care. Their bright orange, yellow, and red flowers bloom prolifically throughout the growing season, providing continuous pollinator support. Both the flowers and leaves are edible with a peppery flavor, adding culinary value to your orchard.
Mexican Bush Sage
Mexican Bush Sage with its violet and purple blooms flowers from spring through fall, requires full sun and is known as a butterfly magnet. This perennial shrub provides long-lasting color and pollinator support, making it an excellent structural companion plant for tangerine orchards.
Mexican Bush Sage is drought-tolerant and deer-resistant, making it ideal for orchards in areas with wildlife pressure. The plant's extended bloom period ensures pollinator activity throughout the growing season, not just during the spring citrus bloom.
Additional Beneficial Companion Plants
Herbs That Attract Pollinators
Many culinary herbs double as excellent pollinator plants while also providing pest-repelling benefits. Herbs like basil, chives, oregano, and thyme not only deter pests but also promote beneficial insect activity around citrus trees.
Rosemary usually blooms early, around the same time as citrus trees, which is a huge benefit to the pollination of citrus flowers. The blue flowers of rosemary are particularly attractive to bees, and the aromatic foliage helps repel certain pests.
Chives produce beautiful purple pom-pom flowers in spring that are highly attractive to bees and other pollinators. Allium roots are relatively shallow, growing to a depth of 12-18 inches, which makes them good companion plants since they won't interfere or compete with the citrus tree's shallow roots.
Nitrogen-Fixing Legumes
While not primarily grown for their flowers, certain legumes provide valuable nitrogen to the soil while also attracting pollinators when they bloom. Legumes leach nitrogen into the ground, which helps very hungry citrus trees, and you can let your legumes grow for a while to build up nitrogen, then cut them back to the ground to release it into the soil.
Clover, sweet peas, and alfalfa are excellent choices for underplanting tangerine trees. These plants improve soil fertility while their flowers attract bees and other beneficial insects. The low-growing habit of clover makes it particularly suitable as a living mulch beneath citrus trees.
Strategic Planting Design for Maximum Pollinator Attraction
Creating Pollinator Clusters
To maximize pollinator attraction, plant companion flowers in clusters or drifts rather than scattering individual plants throughout the orchard. Pollinators are more likely to notice and visit large patches of color, and clustering reduces the energy they expend traveling between flowers.
Plant at least three to five plants of the same species together to create visual impact. This clustering technique is particularly effective with smaller flowers like alyssum or calendula, where individual blooms might not be noticeable from a distance.
Layering for Continuous Bloom
Design your companion planting scheme to provide continuous blooms throughout the growing season, not just during the tangerine flowering period. This strategy maintains a resident population of pollinators in your orchard year-round, ensuring they're present when your tangerine trees bloom.
Combine early bloomers like rosemary and chives with mid-season flowers like lavender and cosmos, and late-season bloomers like Mexican Bush Sage and calendula. This succession planting ensures that pollinators always have a reason to visit your orchard.
Proper Spacing and Placement
Optimal distances between citrus trees and their companions promote air circulation and sunlight exposure, which helps prevent diseases and allows each plant to access the nutrients it needs without competition.
Plant companion flowers outside the drip line of tangerine trees to avoid competition for water and nutrients. The drip line is the area directly beneath the outer circumference of the tree canopy. Most companion flowers should be planted at least 2-3 feet from the trunk to allow for air circulation and prevent moisture buildup that could lead to fungal diseases.
For container-grown tangerine trees, you can plant herbs like thyme, chives, or basil around the citrus container's base and surround patio pots with pollinator-attracting flowers such as calendula.
Creating a Citrus Guild
A citrus guild planting design based on mutually supportive plants includes the citrus tree at center, first ring of herbs (thyme, chives, oregano, basil), second ring of pollinator flowers (calendula, borage, alyssum), third ring of dynamic accumulators (comfrey, yarrow), and ground layer of clover or creeping thyme.
This guild approach mimics natural ecosystems and creates a self-sustaining system that requires minimal inputs while maximizing benefits. Each layer serves specific functions while supporting the overall health of the tangerine tree.
Planting and Maintenance Tips for Success
Soil Preparation
Before planting companion flowers, ensure the soil is well-prepared. Most pollinator-attracting flowers prefer well-drained soil, which aligns with tangerine tree requirements. Amend heavy clay soils with compost or aged manure to improve drainage and add organic matter.
Avoid disturbing the root zone of established tangerine trees when planting companions. Use a hand trowel rather than heavy digging tools, and plant in pockets between existing roots rather than cutting through them.
Watering Considerations
Many pollinator-attracting flowers, particularly Mediterranean herbs like lavender and rosemary, prefer drier conditions than citrus trees. Create microclimates by planting drought-tolerant companions on slightly raised mounds or berms where water drains away more quickly.
Use drip irrigation or soaker hoses to deliver water directly to the root zones of both trees and companion plants, minimizing water waste and reducing the risk of fungal diseases. Adjust watering schedules based on the specific needs of your companion plants, potentially creating separate irrigation zones for plants with different water requirements.
Sunlight Requirements
Ensure that all plants receive adequate sunlight and nutrients, as citrus trees typically thrive in well-drained soil with full sun, so choose companion plants that share these preferences.
Most pollinator-attracting flowers require at least 6-8 hours of direct sunlight daily. In orchards with dense canopy coverage, choose shade-tolerant companions like impatiens or begonias for areas beneath the tree canopy, while planting sun-loving flowers like sunflowers and cosmos in open areas between trees.
Avoiding Harmful Pesticides
One of the most critical aspects of maintaining a pollinator-friendly tangerine orchard is avoiding pesticides that harm beneficial insects. Even organic pesticides like pyrethrin can be toxic to bees and butterflies if applied when flowers are open and pollinators are active.
If pest control becomes necessary, use targeted approaches like insecticidal soap or neem oil applied in the early morning or late evening when pollinators are less active. Better yet, rely on the natural pest control provided by beneficial insects attracted by your companion flowers.
Never spray any pesticide on open flowers, and always read labels carefully to understand the impact on pollinators. Look for products specifically labeled as bee-safe or pollinator-friendly.
Mulching Strategies
Apply a 2-4 inch layer of organic mulch around companion plants and tangerine trees to conserve moisture, suppress weeds, and regulate soil temperature. Keep mulch several inches away from tree trunks to prevent moisture buildup and potential rot.
Some companion plants, like comfrey, can serve as living mulch. Allow comfrey leaves to fall naturally around the base of tangerine trees, or cut them periodically and use them as nutrient-rich mulch. This practice, called "chop and drop," provides a slow-release fertilizer while improving soil structure.
Seasonal Maintenance
Deadhead spent flowers on annuals like cosmos and marigolds to encourage continuous blooming throughout the season. This practice extends the pollinator attraction period and keeps your orchard looking tidy.
Cut back perennial herbs like lavender and rosemary after flowering to maintain compact growth and encourage bushier plants. Divide overcrowded perennials like yarrow and echinacea every 3-4 years to maintain vigor.
Allow some flowers to go to seed at the end of the season to provide food for birds and to enable self-seeding annuals to return the following year. This creates a more sustainable, low-maintenance pollinator garden.
Additional Benefits of Companion Planting
Natural Pest Control
Beyond attracting pollinators, many companion flowers support populations of beneficial predatory insects that control common citrus pests. Some of the best citrus tree companions are those that either deter or draw away harmful bugs.
Flowers like yarrow, dill, and fennel attract ladybugs, lacewings, and parasitic wasps—all of which prey on aphids, scale insects, and other citrus pests. By maintaining populations of these beneficial insects, you can significantly reduce pest pressure without resorting to chemical controls.
Some companion plants act as trap crops, attracting pests away from tangerine trees. Nasturtiums, for example, are highly attractive to aphids and can draw these pests away from citrus foliage.
Weed Suppression
Dense plantings of companion flowers create a living mulch that suppresses weed growth by shading the soil and outcompeting weeds for resources. Low-growing plants like clover, creeping thyme, and sweet alyssum are particularly effective at covering bare soil and preventing weed establishment.
This weed suppression reduces maintenance time and eliminates the need for herbicides, which can harm pollinators and beneficial insects. The dense plant coverage also helps retain soil moisture and prevent erosion.
Soil Health Improvement
Companion planting with citrus trees offers numerous benefits, including improved pollination, natural pest control, enhanced flavor, weed suppression, and eco-friendly gardening practices.
Many companion plants improve soil health through various mechanisms. Nitrogen-fixing legumes add this essential nutrient to the soil, reducing fertilizer requirements. Deep-rooted plants like comfrey and yarrow mine nutrients from deep soil layers and bring them to the surface where shallow-rooted tangerine trees can access them.
As companion plants die back and decompose, they add organic matter to the soil, improving structure, water retention, and microbial activity. This creates a healthier soil ecosystem that supports more vigorous tree growth and better fruit production.
Biodiversity and Ecosystem Resilience
Companion planting helps biodiversity (more species mean more resilience), soil health (dynamic accumulators and nitrogen-fixers rebuild organic matter), and pollinator protection (critical at a time when many bee species are struggling).
A diverse orchard ecosystem is more resilient to pests, diseases, and environmental stresses than a monoculture. By incorporating multiple plant species, you create habitat for a wide range of beneficial organisms, from soil microbes to birds, all of which contribute to orchard health.
This biodiversity also provides insurance against crop failure. If one plant species struggles due to weather or pest pressure, others can fill the gap, maintaining pollinator populations and ecosystem functions.
Special Considerations for Different Growing Situations
Container-Grown Tangerine Trees
If you grow citrus in pots — common in patios and urban settings — you can still apply companion planting strategies, and container citrus benefits just as much from beneficial insects and a biodiverse micro-ecosystem as in-ground trees do.
For potted tangerine trees, plant low-growing companions like thyme, sweet alyssum, or creeping oregano around the base of the container. These plants won't compete significantly with the tree for resources but will attract pollinators and add visual interest.
Surround container-grown citrus with pots of pollinator-attracting flowers like calendula, marigolds, and lavender. Group these containers together to create a pollinator hotspot on your patio or balcony. Move flowering containers closer to citrus trees during bloom time to maximize pollinator transfer.
Small Urban Gardens
In small backyards or patios, use vertical supports to grow vining flowers like nasturtiums near citrus, choose dwarf citrus varieties in pots and underplant with thyme or basil, and incorporate a pot of marigolds to shuttle around citrus containers.
Maximize limited space by using vertical growing techniques. Train climbing nasturtiums or sweet peas on trellises or obelisks placed near tangerine trees. This adds vertical interest while providing pollinator habitat without consuming valuable ground space.
Choose compact or dwarf varieties of companion flowers that won't overwhelm small spaces. Dwarf marigolds, compact lavender varieties, and low-growing herbs are ideal for tight quarters.
Large Commercial Orchards
In commercial tangerine orchards, companion planting can be implemented on a larger scale by establishing pollinator strips between tree rows or around orchard perimeters. These strips can be mowed or managed to control height while still providing pollinator habitat.
Consider planting permanent pollinator hedgerows along orchard edges using a mix of native shrubs and perennial flowers. These hedgerows provide year-round habitat for beneficial insects while also serving as windbreaks and wildlife corridors.
Work with local beekeepers to place hives in or near orchards during bloom time. It is advised to place one colony of bees per two acres for optimal results. Combining managed honeybee colonies with native pollinator habitat created by companion flowers provides the most comprehensive pollination coverage.
Climate-Specific Considerations
Choose companion flowers adapted to your specific climate zone. In hot, arid regions like Southern California or Arizona, focus on drought-tolerant Mediterranean plants like lavender, rosemary, and yarrow. These plants thrive in low-water conditions and won't compete excessively with citrus trees for moisture.
In humid subtropical climates like Florida, select companions that tolerate higher moisture levels and humidity. Pentas, salvia, and tropical milkweed are excellent choices for attracting pollinators in humid climates. The frequent rain might be a bit harder to grow rosemary in climates like Florida, so consider planting rosemary on mounds (around the citrus trees) to increase their soil's drainage.
In cooler climates where tangerine trees must be grown in containers and brought indoors for winter, focus on annual companion flowers that can be replanted each spring, or use perennial herbs in separate containers that can also be moved indoors.
Common Mistakes to Avoid
Planting Too Close to Tree Trunks
One of the most common mistakes is planting companion flowers too close to tangerine tree trunks. This can create moisture buildup around the trunk, increasing the risk of fungal diseases and root rot. Always maintain a clear circle of at least 12-18 inches around the trunk, mulched but not planted.
Choosing Invasive Species
Some attractive pollinator plants can become invasive in certain regions, outcompeting native plants and creating maintenance headaches. Research plants before introducing them to your orchard, and avoid known invasive species in your area. Opt for native wildflowers whenever possible, as these support native pollinator populations without risk of invasiveness.
Over-Fertilizing Companion Plants
Many pollinator-attracting flowers, particularly Mediterranean herbs and wildflowers, actually bloom better in lean soils. Over-fertilizing these plants can result in excessive foliage growth at the expense of flowers, defeating the purpose of companion planting. Fertilize tangerine trees according to their needs, but avoid applying heavy fertilizer to companion flower beds.
Neglecting Water Needs
Different companion plants have varying water requirements. Grouping plants with similar water needs together makes irrigation management easier and prevents over- or under-watering. Don't assume that all companion plants can tolerate the same watering schedule as your tangerine trees.
Planting Only One Type of Flower
Diversity is key to a successful pollinator garden. Different pollinator species are attracted to different flower shapes, colors, and bloom times. Planting only one type of companion flower limits the diversity of pollinators you'll attract. Aim for at least 5-7 different species to support a wide range of beneficial insects.
Monitoring and Measuring Success
Observing Pollinator Activity
One of the most enjoyable aspects of companion planting is observing the increased pollinator activity in your orchard. Spend time watching your tangerine trees during bloom time, noting the types and numbers of pollinators visiting flowers. Compare this to previous years before companion planting to gauge improvement.
Keep a simple journal documenting pollinator sightings, including species if you can identify them. This information helps you understand which companion flowers are most effective and can guide future planting decisions.
Tracking Fruit Set and Yield
The ultimate measure of companion planting success is improved fruit set and yield. Track the number of fruits that develop after flowering, and compare this to previous years. Also note fruit size and quality, as improved pollination often results in larger, better-formed fruits.
Keep records of harvest quantities and timing. Over several years, you should see trends indicating whether your companion planting strategy is improving production. Remember that many factors affect fruit yield, so look for trends over multiple seasons rather than year-to-year variations.
Assessing Pest and Disease Pressure
Monitor pest populations throughout the growing season. A successful companion planting scheme should result in reduced pest pressure as beneficial insect populations increase. Note any changes in common citrus pests like aphids, scale, or whiteflies.
Similarly, track disease incidence. Improved air circulation from proper companion plant spacing and the presence of beneficial microorganisms in healthier soil should reduce fungal disease problems over time.
Seasonal Companion Planting Calendar
Spring
Spring is the critical season for tangerine pollination, as most varieties bloom during this period. Ensure early-blooming companions like rosemary, chives, and early wildflowers are well-established before citrus bloom begins. Plant warm-season annuals like marigolds, cosmos, and sunflowers after the last frost date.
This is also the time to divide and transplant overcrowded perennials, giving them time to establish before summer heat arrives. Apply compost or organic fertilizer to both trees and companion plants to support vigorous spring growth.
Summer
Summer maintenance focuses on keeping companion flowers blooming and healthy. Deadhead spent flowers regularly to encourage continuous blooming. Provide adequate water during hot, dry periods, adjusting irrigation as needed for different plant zones.
Monitor for pests and diseases, addressing problems promptly with organic methods. Summer is also a good time to plant fall-blooming companions like Mexican Bush Sage and asters to extend the pollinator season.
Fall
As temperatures cool, many spring and summer annuals will decline. Remove spent plants and add them to the compost pile. Plant cool-season annuals like calendula and sweet alyssum, which will bloom through fall and into winter in mild climates.
This is an excellent time to plant perennial companions like lavender, rosemary, and yarrow, as cooler temperatures and increased rainfall help them establish strong root systems before winter.
Winter
In mild climates where tangerine trees remain outdoors year-round, winter is a time for planning and preparation. Review your companion planting successes and failures from the previous year, and plan improvements for the coming season.
Order seeds and plants for spring planting. Prepare new planting beds by adding compost and organic matter. In colder climates where container-grown citrus trees are brought indoors, maintain a few pollinator-attracting houseplants like scented geraniums or indoor herbs to hand-pollinate flowers if your tree blooms indoors.
Creating a Sustainable Pollinator Habitat
Providing Water Sources
Pollinators need water just as much as they need nectar and pollen. Create shallow water sources by placing saucers filled with water and pebbles (for landing platforms) throughout your orchard. Change water regularly to prevent mosquito breeding.
Consider installing a small fountain or birdbath near your tangerine trees. The sound of moving water attracts pollinators and birds, while the water itself provides essential hydration during hot weather.
Offering Nesting Sites
Many native bees are solitary and nest in hollow stems, bare ground, or small cavities. Leave some areas of bare, undisturbed soil for ground-nesting bees. Create bee hotels using bundles of hollow stems or drilled wooden blocks to provide nesting sites for cavity-nesting species.
Allow some perennial flower stems to remain standing through winter rather than cutting everything back in fall. These hollow stems provide overwintering sites for beneficial insects.
Avoiding Lawn Chemicals
If your tangerine orchard is part of a larger landscape that includes lawn areas, avoid using lawn chemicals that can harm pollinators. Herbicides, insecticides, and even some fertilizers can be toxic to beneficial insects or contaminate the nectar and pollen they collect.
Consider replacing lawn areas near your orchard with pollinator meadows or low-growing groundcovers that require less maintenance and provide more habitat value.
Integrating Companion Planting with Other Orchard Management Practices
Organic Fertilization
Companion planting works best within an organic or low-input management system. Use compost, aged manure, and organic fertilizers to feed both tangerine trees and companion plants. These organic amendments support soil microbial life, which in turn supports plant health and resilience.
Consider using compost tea or worm castings as liquid fertilizers. These products provide nutrients while also introducing beneficial microorganisms that improve soil health and plant immunity.
Integrated Pest Management
Companion planting is a cornerstone of integrated pest management (IPM), which emphasizes prevention and biological control over chemical intervention. By attracting beneficial insects and creating a diverse ecosystem, you establish natural pest control that reduces or eliminates the need for pesticides.
Monitor pest populations regularly, and intervene only when necessary using the least toxic methods available. Often, simply waiting a few days allows beneficial insect populations to catch up with pest outbreaks, naturally bringing them under control.
Mulching and Soil Conservation
Integrate companion planting with mulching strategies to maximize soil health and water conservation. Use organic mulches like wood chips or straw in pathways and around trees, while allowing living mulches like clover to cover soil in planting beds.
This combination approach provides the benefits of both organic mulch (moisture retention, temperature moderation, weed suppression) and living mulch (nitrogen fixation, pollinator attraction, soil biology support).
Resources for Further Learning
For those interested in deepening their knowledge of companion planting and pollinator conservation, numerous resources are available. The Xerces Society for Invertebrate Conservation offers extensive information on creating pollinator habitat and selecting appropriate plants for different regions.
Your local university extension service is an invaluable resource for region-specific planting recommendations and pest management advice. Many extension offices offer free soil testing and can provide customized recommendations for your orchard.
The Pollinator Partnership provides regional planting guides that list native plants attractive to pollinators in your specific area. These guides are free to download and offer excellent starting points for selecting companion plants.
Consider joining local gardening clubs or permaculture groups where you can exchange ideas and experiences with other growers. Many communities have demonstration gardens showcasing companion planting techniques that you can visit for inspiration.
Conclusion
