Anise (Pimpinella anisum) is a fragrant annual herb with a distinctive licorice-like flavor, used in culinary preparations like baked goods, candies, and liqueurs. It also holds historical significance in traditional medicine for its digestive and respiratory benefits. Companion planting involves strategically placing different plant species together to foster mutual growth and protection.
Why Companion Plant with Anise
Companion planting with anise offers several advantages. Its aromatic compounds deter common garden pests like aphids and lice. Anise’s delicate, lacy white flowers attract beneficial insects such as predatory wasps, hoverflies, ladybugs, and butterflies, which aid in pollination and pest control. Cultivating anise alongside other plants can improve overall plant vigor and enhance the flavor of nearby crops. This strategic placement can also camouflage the scent of other plants, making them less susceptible to specific pests, particularly brassicas.
Beneficial Companions for Anise
Several plants form beneficial partnerships with anise. Coriander (cilantro) is an excellent companion, speeding up anise germination. This pairing also repels aphids and spider mites, while attracting beneficial insects like predatory wasps and hoverflies.
Anise thrives near beans and members of the cabbage family, including mustard. Studies show anise can significantly reduce cabbageworm eggs on nearby cabbage plants.
Grapes also benefit from anise’s presence. Dill, with its similar feathery foliage, attracts beneficial insects such as ladybugs, syrphid flies, and predatory wasps, which control aphid and spider mite populations.
Plants to Keep Away from Anise
While anise offers many benefits, certain plants should be kept at a distance to prevent adverse effects. Basil is an incompatible companion and should not be planted near anise. Carrots and radishes are poor neighbors, as their proximity can inhibit anise’s growth. Rue should also be avoided near anise due to potential growth inhibition.
Fennel is a problematic companion for most garden plants, including anise. It exhibits allelopathic properties, releasing chemicals that inhibit or harm nearby plants. Growing fennel too close to anise or dill can also lead to cross-pollination, negatively impacting seed flavor and quality.
Tips for Successful Anise Companion Planting
Successful companion planting with anise requires understanding its environmental needs. Anise needs full sun exposure.
The soil should be light, well-drained, and have a neutral to slightly alkaline pH (6.0-7.5). Avoid heavy or waterlogged soil to prevent root issues.
Direct sow seeds into their permanent location, as anise does not transplant well. Once seedlings emerge, thin them to 6 to 12 inches apart for adequate air circulation and sunlight.
Consistent watering is important during establishment, keeping the soil lightly moist, especially during germination. Observing the health of both anise and its companions helps gardeners adapt practices for optimal growth.
