Alpine Current Shrubs #393276

Asked April 12, 2017, 10:47 AM EDT

I planted 6 alpine current shrubs about 6-10 years ago. They are on our property line. They are living and green but they have only reached about 2 feet in height max. I have some of the same shrubs on the other side of our property and they are growing tall each year and I prune them back. I am trying to figure out what is wrong with them and if I should just pull them out. The neighbor have two large black walnut trees in their yard. Could this be the problem? And what kind of shrubs can I plant there in place of them? We would like to have the shrubs for privacy between the two properties.

Expert Response

Most berries are sensitive to the juglone produced by Black Walnut. Current isn't on the list but if they are getting as much sun and water as the plants on the other side of your lot then Black Walnut toxicity is likely.
There are many choices of shrub that tolerate juglone.
Thanks for mentioning the black walnut, it was a very helpful observation.
