I have miniature lilac bushes (Bloomerang, Jodee, and Tinkerbell). I have a problem with them dying either in the summer months or not surviving the winter (or rabbits eat them off). A person from my garden club remarked that the reason they were dying is because I have black walnut trees close by. If that is the reason, if I would cut down the walnut trees, would that solve the problem? Is the problem with the walnut trees in the foliage or in the roots, or is there another problem?

The black walnut may indeed be causing the ill health of these bushes.

Here is a link that describes the interaction between the Juglone and other plants:

As you can see, simply removing the tree may not solve the problem.

Thanks for contacting AaE. Please do so again if you have further questions.

Thank you so much! You answered my question. Now, I will have to plant a different species of shrub. You were very helpful.
