Trees and tomato wilt


Can the presence of certain species of trees affect the health of tomato plants? - Mike -

    Tomatoes or other susceptible plants like potato, blackberry, apple, and asparagus should not be grown near black walnut or other trees which produce juglone like some hickory trees. The removal of walnut trees may not have an immediate effect since the toxin can persist in the inner bark of roots for several years. Do not plant tomatoes for at least two years after the removal of walnuts. I hope this has helped. Ruth
