Calamondin citrus (Citrus × microcarpa) is a popular small citrus tree known for its vibrant fruit and fragrant blossoms. Native to Southeast Asia, it is cherished by gardeners for its ornamental appeal and edible fruit. Proper care throughout the year ensures a healthy, productive calamondin citrus tree. This calendar provides month-by-month guidance to help you maintain your plant all year round.
January
In January, focus on protecting your calamondin from cold temperatures. If you live in a cooler climate, bring the plant indoors or provide frost protection. Water sparingly, allowing the soil to dry slightly between waterings. Prune any dead or damaged branches to promote healthy growth for the upcoming season.
February
As days start to lengthen, begin fertilizing with a citrus-specific fertilizer. Keep the plant in a warm, sunny spot. Continue to protect it from frost and cold drafts. Check for pests like scale or aphids and treat promptly if found. Prune lightly to shape the tree and remove crossing branches.
March
March signals the start of active growth. Increase watering as the weather warms. Apply a balanced fertilizer every 4-6 weeks. If your calamondin is outdoors, ensure it is in a location with full sun. Repot if the plant has outgrown its current container. Prune to encourage a strong structure.
April
April is a great month to promote flowering. Continue regular watering and feeding. Keep an eye out for pests and treat as necessary. You may notice blossoms beginning to appear, which will develop into fruit. Mulch around the base to retain moisture and regulate soil temperature.
May
In May, your calamondin should be actively flowering and setting fruit. Ensure consistent watering, especially during warm days. Fertilize every 4 weeks with a citrus fertilizer high in potassium. Thin out excess fruit if the tree is heavily laden to prevent stress and promote larger fruit size.
June
June offers longer days and ample sunlight. Keep up with watering and fertilizing. Protect the plant from strong winds that can damage blossoms or young fruit. Consider applying a foliar spray to boost nutrient uptake. Watch for pests like spider mites and treat promptly.
July
July is peak growing season. Water regularly, especially during hot weather, ensuring the soil remains moist but not waterlogged. Continue fertilizing every 4 weeks. Harvest ripe fruit as it matures. Prune lightly to maintain shape and remove any overcrowded branches.
August
August provides an opportunity to assess your plant’s health. Keep watering consistently and apply fertilizer as needed. Remove any fallen or diseased fruit to prevent pest issues. Protect the plant from intense afternoon sun if it shows signs of stress.
September
As temperatures begin to cool, reduce watering frequency slightly. Continue feeding every 4-6 weeks. Harvest remaining fruit and prune to shape the tree for the upcoming dormant period. Check for pests and diseases, treating as necessary.
October
October is ideal for preparing your calamondin for winter. Gradually decrease watering and stop fertilizing by mid-month. Protect the plant from early frosts if outdoors. Prune lightly to remove any dead or damaged branches and promote good airflow.
November
In November, focus on winter protection. Bring the plant indoors if possible or shield it with frost cloths. Water sparingly, only when the soil is dry. Maintain good light exposure to prevent legginess and encourage healthy roots.
December
December is a quiet month. Keep the plant in a bright, cool location. Water only enough to prevent the soil from completely drying out. Avoid fertilizing during dormancy. Use this time to inspect the plant for pests and plan for the upcoming growing season.
