Allelopathy - 1. Allelopathy is the production of substances by one plant that adversely affect other plants nearby. Roots of black walnut produce substances-juglonines-that inhibit growth of tomatoes and other plants near the tree roots. Ivy (Hedera sp.) may cause a decline of boxwood (Buxus spp.). The substances may leach from leaves, or from the roots [2]. Be alert for allelopathic problems.
2. Root exudates from some plants can kill many soil organisms. Chemical exudates from leaves and roots may kill or stall growth of other plants.
