Certain types of walnut trees can wreak havoc in your garden. Black walnuts especially can cause all types of growth problems. Learn to fix these problems yourself and keep your trees by reading the tips below. When you're done, watch our video explanation for more information on the subject.
Why Walnut Trees Are Problematic Near Gardens
Walnut trees make a chemical, called juglone, which is excreted from all parts.
Even though Black Walnut is recognized by gardeners as being the most problematic, the English walnut also produces this chemical to a lesser degree. This chemical is a protective response to assure survival of the tree by inhibiting the growth of nearby plants. It mimics the effects of not watering plants, and can cause plants near the trees to die, or be noticeably smaller and more frail than surrounding plants.

Most of the items you may need to fix walnut tree problems can be found at a local garden center, shopping area, or in your back yard. Just remember that you won't likely be able to garden or plant directly under a walnut tree - especially a Black Walnut tree.

- Sensitive plants located beneath the cover of a walnut tree are most susceptible to contact with juglone. This is why they should be removed from the tree canopy, and preferably in raised beds.
- Juglone isn't poisonous to humans, but can contribute to allergies during the spring.
- Walnut trees also require special care and irrigation, which should not be overlooked when considering the type of gardens you want to plant near them.
