Can you top a walnut tree?
It is best to remove the little stub branches before they grow over ½ inch (1.5 cm.) in diameter. The tree can seal off pruning wounds much more easily when they are smaller. Additionally, walnut tree pruning involves making sure that all side branches remain subservient or lower than the height of the central leader.
Why does a walnut tree stop producing walnuts?
Like many trees that produce nuts and fruits, walnut trees are prone to a reproductive pattern known as alternate bearing. This is characterized by alternating years of heavy crop yield followed by light or absent nut production.
Can you keep a walnut tree small?

Can I mow over walnuts?

What can I do with walnuts from my yard?

Are there male and female walnut trees?

Can you neutralize juglone?
A. The toxin, called juglone, cannot be easily neutralized — and it can persist in the soil for years, so even a chain saw won’t help. Juglone is present in all parts of the tree, but is especially strong in the roots, which extend far beyond the canopy.
How do you pick walnuts out of your yard?

Why do walnuts fall early?
Sometimes nut-bearing trees, such as hickory, walnut, and pecan, drop their fruit before full maturity. At times, it can be a natural shedding of a portion of the nut crop. Other causes can be more problematic, including adverse weather conditions, poor tree health, inadequate pollination, insects, and disease.
Do you need 2 walnut trees to produce nuts?
Walnut Tree Pollination All walnut varieties are self-fertile, meaning that the pollen can travel from the male parts to the female parts of the same tree and under this procedure the tree can produce nuts. Thus, a single tree can theoretically produce nuts without needing other walnut trees around.
Do all black walnut trees produce walnuts?
Every black walnut tree grows wood in the form of limbs, trunk and roots. And as the tree matures, every walnut tree will produce at least a small nut crop.
What does a lot of walnuts mean?
