Lemon trees require specific conditions to thrive, including a pest-free environment, ample sunlight, and nutrient-rich soil. Yarrow (Achillea millefolium) is a beneficial herb that can be planted alongside lemon trees to help ward off common pests and enrich the soil for healthy fruit production. Yarrow is a perennial herb with beautiful feathered flower clusters, high drought tolerance, and thrives in USDA Hardiness Zones 3 through 9. Planting yarrow in the spring can result in blooming through summer and fall, adding color and beauty to your garden.
Pest control and soil benefits
Common citrus pests like aphids, mealybugs, and whiteflies can cause damage to lemon trees, affecting fruit yields and quality. While yarrow itself does not repel pests, it attracts beneficial insects like ladybugs and lacewings that eat problem bugs and help control pest populations. Yarrow also attracts pollinators like butterflies and parasitic wasps that can benefit your garden. Additionally, yarrow’s deep root system helps aerate soil, improve water infiltration, and reduce weed growth around lemon trees.
How to grow yarrow with lemon trees
Growing yarrow plants requires ample growing room, sunlight, and pruning. Yarrow plants prefer sun and minimal water, but they can become invasive if not properly maintained. To control yarrow growth, consider planting it in a separate pot or grow bed with sufficient space for its root system. Regular pruning and monitoring for new sprouts can prevent yarrow from taking over your garden. If starting from seed, plant yarrow in well-drained soil indoors before transplanting outdoors after the last frost. Ensure yarrow plants receive at least six hours of sunlight per day to thrive.
