🤝 Companions (5)

Wormwood deters currant borers and aphids; planted at bush edges it protects without competing through different root zones.
🤝 Fruit Trees
Wormwood planted at orchard edges deters codling moths, apple maggot flies, and peach borers; its allelopathy doesn't affect deep-rooted mature trees.
Both are drought-loving Mediterranean perennials; combined scents create a powerful insect-repellent border hedge.
Wormwood's strong scent deters aphids, rose chafers, and Japanese beetles from roses; its silver foliage complements rose colors.
🤝 Rue
Both are powerfully bitter, insect-repelling Mediterranean herbs; combined they create an extremely effective pest-barrier planting.

⚠️ Keep Apart (7)

Wormwood is allelopathic to anise; inhibits anise germination and stunts growth of any anise plants that do emerge.
Wormwood is strongly allelopathic , its root exudates and fallen leaves inhibit bean germination and kill nitrogen-fixing bacteria.
Wormwood's root exudates stunt carrot root development and reduce germination; carrots planted near wormwood produce small, bitter roots.
Wormwood suppresses dill growth through root allelopathy; dill's delicate flavor can be tainted by wormwood proximity.
Wormwood's allelopathic compounds inhibit pea root development and nodulation; peas will fail to thrive within 3-4 feet.
Despite being recommended as a companion by some, wormwood's allelopathy can stunt sage growth if planted within 3 feet; keep significant distance.
Wormwood inhibits tomato growth through strong allelopathy; even leaf-wash from wormwood rain runoff can stunt tomatoes.

📝 Growing Notes

Powerful allelopathic plant , root exudates and leaf litter inhibit germination and growth of many other plants. Do not plant in vegetable gardens. Use as a border hedge where its growth-inhibiting properties are beneficial (edges of property, paths). Primary ingredient in absinthe (with anise and fennel). Extremely bitter , one of the most bitter plants known. Silver-gray feathery foliage is highly ornamental. Deer and rabbit proof. Repels moths (use dried leaves in sachets). Attracts few beneficial insects. Do not plant near legumes or vegetables.
