Roads, sidewalks and foundations can all suffer structural issues from tree roots. [7] Several methods of control have been attempted, from barriers to encouraging growth in desirable directs. Selection of plants with root systems that will not conflict with nearby structures is the most effective method of damage control.
Trunk injection or endotherapy also known as vegetative endotherapy, [1] [2] [3] is a method of target-precise application of pesticides, [4] [5] [6] plant resistance activators, [7] or fertilizers [8] into the xylem vascular tissue of a tree with the purpose of protecting the tree from pests, or to inject nutrients to correct for nutrient deficiencies.
Root barriers are also used to separate plant roots from each other. In particular, walnut trees secrete the chemical juglone which is toxic to other plants but the use of root barriers can prevent the yield reduction that would normally occur when walnut trees are alley cropped with maize as often occurs in the American Midwest.

Here are some common invasive plants and how to identify and manage them. ... an edible plant that releases a chemical from its roots that can damage the fungi in the soil that plants and trees ...
Once the plants grow to full height, their enormous leaves shade out all the space below them, preventing any other plant from growing nearby. It also has a shallow root system that facilitates soil erosion. [3] The tree can grow to a height of 15 metres (49 ft) and has very large leaves, each up to 1 metre (3.3 ft) in length.
Knowledge of how to use these hormones to induce rhizome growth could help farmers and biologists to produce plants grown from rhizomes, and more easily cultivate and grow better plants. Some plants have rhizomes that grow above ground or that lie at the soil surface, including some Iris species as well as ferns, whose spreading stems are rhizomes.
Falik et al. subjected the root of an externally-induced plant to mannitol in order to inflict osmotic stress and drought-like conditions. Five unstressed plants neighbored both sides of this stressed plant. On one side, the unstressed plants shared their root system with their neighbors to allow for root communication.
