If i cut my walnut yrees down how long will the jugline remain in the ground and affect my gardens? What do i need to do besides cut down the trees? Do i need to replace the soil in my gardens?
Anoka County Minnesota
Roots in the soil, breakdown may take up to two months after the living walnut tree has been removed.
What about my other 2 questions?
You need to do nothing juglone will dissipate in about two months. You can replace the soil, however, you will need to replace about a foot of soil in a fifty foot radius of the tree. You might try to remove all the tree roots, however, many tiny hair roots will still require about two months for juglone to degrade.
