Blazing star (Liatris spp.) is a beautiful perennial that adds vibrant color to gardens and attracts pollinators like bees and butterflies. However, pests such as deer, rabbits, and insects can threaten its health and appearance. Creating DIY pest barriers is an effective, eco-friendly way to protect your blazing star without resorting to chemical pesticides.
Understanding Common Pests That Affect Blazing Star
Before building barriers, it’s important to identify the pests that commonly target blazing star. These include:
- Deer and rabbits, which may eat the foliage
- Insects such as aphids and beetles that feed on stems and flowers
- Slugs and snails that damage young plants and blooms
DIY Pest Barriers for Deer and Rabbits
To deter larger animals like deer and rabbits, physical barriers are most effective. Here are some simple DIY solutions:
Wire Mesh Fencing
Use galvanized chicken wire or hardware cloth to create a protective cage around your blazing star. Ensure the fencing is at least 2 feet high and bury the bottom 6 inches underground to prevent animals from digging underneath.
Plant Barriers
Planting deterrent plants such as garlic, onions, or marigolds around your blazing star can help repel pests naturally. These can be combined with physical barriers for enhanced protection.
DIY Insect Barriers
Insects can be managed with physical barriers that prevent access to flowers and stems. Here are effective methods:
Row Covers
Use lightweight garden fabric or insect netting to cover your blazing star during peak pest seasons. Secure the edges with stakes or weights to prevent pests from crawling underneath.
Sticky Traps
Place yellow sticky traps near your plants to catch flying insects like beetles and aphids. Replace them regularly for ongoing protection.
DIY Slug and Snail Barriers
Slugs and snails can be deterred with barriers that prevent their access to plants. Consider these DIY options:
Crushed Eggshells or Coffee Grounds
Sprinkle crushed eggshells or coffee grounds around the base of your blazing star. These create a rough texture that slugs and snails avoid crossing.
Beer Traps
Bury shallow containers filled with beer at soil level near your plants. The pests are attracted to the beer and drown in the liquid.
Additional Tips for Pest Management
While barriers are effective, combining them with cultural practices enhances protection. Consider the following:
- Maintain healthy, well-watered plants to resist pests
- Remove debris and weeds that harbor pests
- Inspect plants regularly for early pest detection
- Encourage natural predators like birds and beneficial insects
By implementing these DIY pest barriers and practices, you can enjoy the vibrant blooms of your blazing star while minimizing pest damage in an environmentally friendly way.
