Oregano and yarrow can be wonderful garden companions because they both need less water to thrive. But the character of both of these plants is one of invasion. Therefore, it is not advised to put them side by side on the ground.

Every novice yarrow grower wonders whether this plant pairs well with other plants in the garden. This is a valid question, in fact, as yarrow has a bad image for spreading quickly—almost to the point of being invasive.

Actually, yarrow can make a good companion plant. Combining this plant with other healthy plants might provide you with several advantages.

For example, aphid-eating bugs, migratory bees, and butterflies are attracted to this plant, which is one of the main reasons it makes a suitable companion plant.

Additionally, yarrow’s fragrance deters dangerous insects.

Additionally, because it grows to a height of at least 3 feet, the yarrow plant can provide shade for low-growing plants. So, under the partial shade provided by yarrows, plants that can tolerate shade can grow and prosper. 

Finally, the yarrow plant adds nutrients to the soil, another advantage of using it in your garden. Potassium, magnesium, copper, calcium, and phosphorus are nutrients that this plant restores in the soil.

The yarrow can, however, become invasive if the plant’s expansion is not properly controlled. The University of California Integrated Pest Management Program attests to this fact. In addition, pollen and seeds of the plant are transported by wind, making it challenging to control its spread.

The Not-So-Friendly Yarrow Companion Plants

Undoubtedly, the yarrow is an excellent plant to combine with a variety of other garden crops. Nevertheless, several plants shouldn’t be grown close to this host plant. We can say that the unfriendly companion plants we will mention in this section will not make your yarrow happy.

Keep in mind that the yarrow spreads across a vast region and becomes tall. So, it is not a good idea to grow flowering plants that love the sun close to the yarrow, as doing so would create shade and devoid the plants from getting the proper sunlight. Having stated that, yarrow plants should not be grown with the following sun-loving blooming plants.

  • Aster
  • Sedum
  • Bee balm
  • Butterfly weed
  • Purple coneflower
  • Lamb’s ear

The following plants should not be grown together with yarrow: zucchini, pumpkin, cucumber, and squash. The fact that these plants and yarrow draw powdery mildew is one of the main arguments against accepting them. As a result, there is a good likelihood that these pests may attack your garden if they are combined.

The Takeaway

So, this was all about yarrow companion plants.

After examining all the information, we would like to make the following recommendation: anytime growing yarrow close to any plant, keep in mind the height and potential invasiveness. To protect the growth of the nearby plants, you should attempt to control its spread.
