Do black walnut trees prevent other plants from growing?
Black walnuts have a chemical called juglone which can affect the growth of other trees. “It’s a natural inhibitor of growth,” said Dr. Michael J. O’Connor, a professor of entomology at the University of Illinois at Urbana-Champaign, who was not involved in the study.
“If you have a tree that’s already dead, it’s not going to be able to compete with the dead tree for nutrients, so it will die.
What kills a black walnut tree?
Glyphosate or another all-purpose herbicides can be sprayed into the cuts in the trunk. Up to 2 inches above the soil surface, spray the herbicide directly on the trunk for plants less than 6 inches in diameter. For larger trees, use a sprayer with a high-pressure nozzle, such as a garden hose, to spray from the top of the tree down to the ground.
The spray nozzle should be positioned so that the spray is directed at the root zone, which is the area where the plant is growing. If you are spraying a tree that is more than 2 feet tall, you will need to place the nozzle at a height of at least 3 feet above ground level. You may also want to add a small amount of water to your nozzle to keep it from drying out too quickly.
