The grass under my english walnut tree is not doing well. What can i do to help the grass grow?
Rate This FAQ
Walnut trees, black walnut & English walnut and other closely related trees, have a chemical compound called juglone, which inhibits growth of other plants. This gives walnut a competitive edge, so other plants have a more difficult time growing because of juglone.
We do not recommend people to collect leaves, nuts, or twigs from walnut trees and put into compost exactly for this reason. Grass, groundcovers, many plants will not survive under walnut trees. Best advice it to cover the roots of trees with 2-4 inches of organic mulch such as bark nuggets that will prevent weeds, moderate moisture and temperature of soil as far out as the drip line of the tree.

- I have a relatively young peach tree which just split down the middle today, I'm assuming due to the weight of the peaches. I have cut off some of the branches and removed some peaches to help lighten the load. I called a nursery and they said in addition to doing that I should bring the branches back together and secure them together in attempt to save the remaining peaches. Then this fall I need to completely remove the partially broken branches. My questions for you are: Is this tree salvageable if I cut off 2/3 of its branches and will the peaches I've taken off ripen under any conditions?

- We have 2 honeylocust trees in our yard. I would guess "Imperial honeylocust". They seem to be about 15 years old or so. They are spaced about 20 feet apart. This spring one has leafed out and the other is still not budding or leafing out. Over the winter, the one that is not budding turned bright red on the trunk, which we have never seen before. The tree is getting a very few buds and leaves on some main branches (like suckers) but no buds or leaves on the outer limbs. Is there anything we can do to save this tree?
