Some Not-so-Good Yarrow Companion Plants

Cucumbers, melons, zucchini, pumpkins, and squash are better not to be grown nearby yarrows because they are susceptible to powdery mildew (a common fungus that affects a wide range of plants), and so is yarrow.

Don’t grow these crops near yarrow. Because if even one of them gets powdery mildew, there are fair chances that all of them (including yarrows) will be affected by this fungal disease, as it spreads very fast.

Some gardeners even recommend not growing coneflowers, bee balm, or butterfly weeds near yarrows. Because all of them differ in height, there can be issues like one crop blocking the sunlight for the other. If you think that you can manage this issue perfectly, you may grow coneflowers and butterfly weed nearby yarrows if you want to.

Can Yarrow Be Planted With Vegetables?

Vegetables, being the companion plants of yarrows, benefit from the beneficial-insects-attracting property of the yarrows and the insect-repelling abilities of the yarrows. Brussel Sprouts, Broccoli, Cauliflower, Cabbage, and other Brassicas are known to take benefits from yarrows.

Since some plants like Brassicas prefer to be kept cooler, growing nearby yarrows is best for them as yarrows provide shade to their companions.

Garlic and tomatoes are some other good yarrow companion plants. Since yarrows help in improving the growth of garlic, garlic is a good companion plant for yarrows. Yarrows attract pollinators, and tomatoes are the ones that take the most advantage of yarrows’ ability.

Where Should You Plant Yarrow in Your Garden?

Now that we have discussed what makes the yarrows good companion plants, what to plant near them, and whatnot, you may want to know where you should plant your yarrows in your garden. You can keep the following points in your mind while planting yarrow in your garden:

  • Yarrow needs full sunlight to grow. Yarrows grow leggy in shade or partial sun. So, choose the area that receives full sunlight. It will encourage compact growth for both yarrow and yarrow companion plants.
  • Well-drained soils are known to be best for yarrows. Yarrows can’t tolerate all the time; they need hot and dry conditions to thrive. We recommend loamy soil for growing yarrow.
  • Don’t grow yarrow in soil that’s too enriched with nutrients. It may result in overgrowing of yarrows. They may be too tall in this way and will shadow their nearby plants more than they need to. You should plant them where the soil is average, and then you can give the plants a good start by supplementing the soil with a bit of compost.

How Do You Keep Yarrow From Spreading?

The only problem that the yarrows will give you is their ability to overgrow and take up the space of their nearby plants. What can you do to stop that? You can divide the yarrow plant to maintain its invasive growth. Dig up clumps of yarrows and put the leaves in your compost pile or plant it somewhere else.

Common yarrow spreads by underground stems and self-sowing. 

  • To control spreading by underground stems, you need to pull up new sprouts and the attached stem just below the soil surface. Remember to pull up fresh sprouts and the attached stem in early spring and during the growing season because it is easier to pull up spreading stems after rain when the soil is soft.
  • Self-sowing is easy to control; you simply need to trim spent blooms. Also, do not forget to remove spent flowers in the yarrow to prevent plants from reverting to the parent form. 
  • As the National Gardening Association recommends, cut back yarrow plants to within 1 to 2 inches (2.54 to 5.08 cm) above the soil to eliminate places where pests can overwinter and give room for new green growth to emerge in spring. 

Does Yarrow Come Back Every Year?

Generally, yarrow basal leaves stay green year-round in more temperate climates, but they will die back with a hard freeze in colder climates. Yarrow thrives all summer long, sending up 1- to 3-foot-tall flower stalks to form a dense mound of fern-like basal leaves.

The National Gardening Association suggests cutting back yarrow plants to within 1 to 2 inches (2.54 to 5.08 cm) above the soil line after the first killing frost in autumn. Cutting back yarrow plants in autumn will eliminate places where pests can overwinter and allow new green growth to emerge in spring. And sprinkle a 2-inch-thick layer of mulch around the plants to insulate the yarrow roots better.
