September 3, 2011Q.Shrubs That Tolerate Shade and Black Walnut Tree
We want to plant shrubs and other plants along the foundation of our house. The front of the house faces south and has shade all day due to an oak tree, a giant cottonwood and a black walnut tree that is 3' from the corner of the house. The west side of the house is mostly shade and the walnut is at the southwest corner of the house. We tore up all the landscaping 10 years ago and don't remember what was planted there. We live in St. Paul, MN.

Certified ExpertA.I believe you can plant hydrangea, forsythia and hibiscus near black walnut. Many trees, though they may reach over 5 ft., are compatible as well: arborvitae, flowering dogwood and Japanese maple are a few. This article may offer additional suggestions too: https://www.gardeningknowhow.com/edible/nut-trees/black-walnut/black-walnut-compatible-plants.htm

Certified ExpertA.All but a few plants can survive black walnut. Even when it is shredded for mulch, the wood will be allelopathic as it decomposes and kill many plants.

Certified ExpertA.Black walnuts are poisonous to most plants, so it is possible that the soil near the tree and surrounding area has some toxicity which may be affecting your hydrangeas. You may need to consider moving your hydrangeas further away if possible or grow them in raised beds or containers.

Certified ExpertA.It is not a potato. It actually looks like a black walnut sucker. Did you have a black walnut growing near there that you cut down?
