What not to plant near yarrow
So far you might think Yarrows are the best companion plant for any crop. Let me tell you that’s not the case. Yarrow attracts powdery mildew. I avoid planting it in close proximity to vegetables that are susceptible to the disease, such as squash, zucchini, pumpkins, cucumbers, and melons. The yarrow plant, along with several other crops, is vulnerable to powdery mildew.
I make it a practice to keep crops that have the potential to be affected by the same diseases apart from one another. This allows me to better manage the problem in the event that it manifests itself on one of the plants. If you don’t take action soon enough, powdery mildew may easily spread to other crops and plants if you don’t stop its spread.
Some gardeners believe that yarrow should not be grown with coneflowers, bee balm, or butterfly weeds. On the other hand, about the same number of gardeners will tell you that yarrow makes an excellent companion plant for these blooms. Before planting, I keep in mind that yarrow can prevent sunlight from its companion plants. Also, I ensure that my yarrow does not become too widespread.
Growing yarrow close to other plants requires careful consideration due to the plant’s potential to become invasive and the height it may reach.
Be certain that it is not obstructing the sunlight from reaching other flowers that need full sun, such as butterfly weeds and coneflowers.
Also, think about how you will manage its expansion in the future. If you want to use the “mow it over” approach in the autumn, then you need to make sure that you have planted it in an area where you will be able to use this method. And if you don’t want to constantly prune it and divide the plants, it could be easier to cultivate it on its own rather than planting it next to other kinds of plants or flowers.
