• Leave some areas of your yard unmanicured, allowing native plants like yarrow to grow and flourish.
Attracting Beneficial Insects
Yarrow is a pollinator paradise, attracting beneficial insects like bees, butterflies, and hoverflies that are essential for plant reproduction. This is largely due to its unique combination of nectar-rich flowers and host plants, which provide the perfect food source for these vital creatures.
One of the key reasons yarrow is so attractive to pollinators is its rich supply of nectar. Each of its small white or yellow flowers contains a wealth of nectar that serves as a primary source of energy for pollinators during their busy days of collecting pollen and water. This bounty is particularly important for honeybees, which rely on yarrow as one of their preferred sources of nectar.
But it’s not just the nectar that makes yarrow so appealing to pollinators – its foliage also serves as a vital host plant for beneficial insects like hoverflies and ladybugs. These insects lay their eggs on the leaves of yarrow plants, providing them with essential nutrients when they hatch. As a result, incorporating yarrow into your garden not only supports local pollinator populations but also promotes biodiversity by creating a haven for these beneficial insects to thrive.
Repelling Pests
Yarrow’s pest-repelling properties create a haven for pollinators by protecting them from unwanted pests. This is especially crucial as many pollinator species are vulnerable to parasites and diseases that can be spread through contact with infected individuals or contaminated food sources.
Some of the most common pests that yarrow repels include aphids, whiteflies, and spider mites – all of which feed on plant sap and can weaken a plant’s immune system. By planting yarrow nearby, you can significantly reduce the risk of these pests taking hold in your garden. In fact, studies have shown that yarrow is particularly effective against the onion thrips, a common pest that can devastate pollinator-friendly plants like lavender and coneflower.
To maximize yarrow’s pest-repelling benefits for your pollinators, plant it in close proximity to other flowering plants and herbs that attract beneficial insects. This will create a diverse ecosystem where predators like ladybugs and lacewings can thrive, helping to maintain a natural balance of pests and beneficial organisms.

Growing Yallow from Seed or Cuttings
To grow yarrow successfully, you’ll want to learn how to propagate it from seed and cuttings, which can be a bit finicky but ultimately rewarding. Let’s take a closer look at these methods.
Starting Seeds Indoors or Outdoors
Starting seeds indoors allows you to get a head start on the growing season and can be especially beneficial for yarrow, which prefers cooler temperatures to germinate. Begin by preparing seed trays or small pots with a good quality seed starting mix. Sow one yarrow seed per cell, about 1/8 inch deep, and gently firm the soil in place.
For direct sowing outdoors, wait until the last frost date has passed for your area. Yarrow seeds are tiny, so it’s essential to sow them thinly, about 1/4 inch deep, and 12-18 inches apart. Press the soil down firmly to ensure good contact with the seed.
Regardless of whether you’re sowing indoors or directly in the garden, keep the soil consistently moist but not waterlogged during the germination period, which typically lasts 7-14 days. Once seedlings have emerged, provide them with plenty of natural light and maintain a consistent moisture level to promote healthy growth.
Propagating Using Cuttings
Propagating yarrow using cuttings is a great way to multiply this valuable pollinator plant. To do so successfully, start by selecting healthy, vigorous stems with plenty of leaves and at least two nodes (the joint where a leaf meets the stem). Cut these stems from established yarrow plants in late spring or early summer when the plant is actively growing.
Cut the stems at a 45-degree angle, just above a node, using sharp, clean scissors or pruning shears. This will help prevent water from collecting on the cut end and promote root growth. Remove lower leaves, leaving only two sets of leaves at the top to reduce moisture loss and encourage rooting.
Dip the cut ends into a rooting hormone powder or liquid before planting to enhance the chances of successful propagation. Plant the stem cuttings in a seed starting mix, firming the soil gently around them. Keep the soil consistently moist but not waterlogged, providing bright, indirect light until roots develop. Within 4-6 weeks, you should see new growth and be able to transfer the young plants into individual pots or directly into your garden, where they will provide a rich source of nectar for pollinators.
