April 1, 2019A.You can compost these parts of the tree, though you will need to wait the appropriate time before using this composted material.

August 20, 2019Q.picking walnuts early
I have lots of walnuts on my tree for the second year but last year squirrels stripped the tree virtually overnight. Having just seen them again in my tree is there any point in me picking the walnuts still green and definitely not ripe yet. Will they ripen off the tree?

Certified ExpertA.I couldn't find any refernce that said nuts could be picked early. Since harvesting involves shaking the nuts loose from the tree, unripe nuts probably won't drop.

37355Q.Why Would Walnuts Be Moldy On The Inside When Cracked?
We bought property with 2 mature grafted walnut trees. We didn't have any fruit last year because of a late spring freeze. This year, we had plenty of nuts, but when cracking them open, 80% of them were moldy on the inside. No sign of breach in the shells. What would cause this? Is there any way to keep it from happening next year?

Certified ExpertA.It sounds like a very common Walnut blight, Xanthomonas juglandis

February 25, 2020Q.Can I prune or ‘reduce’ a walnut tree?
I planted the walnut tree several years ago at the bottom of my garden not realising how tall and wide it would grow. It produces quite a lot of nuts. I don't want to chop it down, just reduce its reach as its leaves drop over the fence and it blocks light to the garden when in leaf. Help!? Thanks, Helen

Certified ExpertA.The short answer is yes, you can lightly or moderately reduce the height and spread of a walnut tree without harm if done properly with horticulturally correct pruning methods. But major crown reduction, topping, with stub cuts will do more harm than good.
The more complete answer is that you should seriously consider how much crown reduction is needed and how this will be done. There are consequences with severely altering the natural form and beauty of a tree.
Consider hiring a professional, a certified arborist, who can assess and offer recommendations for "moderate crown reduction pruning" (25% maximum is the rule of thumb for Best Management Practices, and even that is a lot.) Or consider entire tree removal if the reduction indicated and possible annual maintenance pruning is not going to be satisfactory.https://www.gardeningknowhow.com/edible/nut-trees/walnut/how-to-prune-walnut-trees.htm

Certified ExpertA.Not to humans, but it can affect dogs and horses, as well as other plants. Although, you would already notice the effects of the tree long before the sap started leaking. It can be hard to grow many plants around them.
