My neighbour hood is 100 years old and over the last 15 years all the Norway maples have died and only the black walnuts remain thankfully giving shade and a beautiful green coverage. They can be dangerous when they drop. The English walnut tree takes years before maturity, while the black walnut tree grows very fast. We have a squirrel infestation now and they destroy everything. You'll typically see 2 or 3 green rounds growing near where the leaf-bearing twigs shoot off from thinner branches. Submitted by Steve on August 21, 2020 - 10:35am. Be aware that if you live in a rural area, that Black Walnut is highly toxic to horses. I have over 100 young black walnut trees and my friend has at least one old butternut tree. Before I just mowed them each year but now that I use a Battery powered SunJoe mower, I rake the nuts 1st (less power than a gas mower). In earlier times there were giant black walnut trees, 30' in circumference and more than 200' tall. Just like the name implies, they produce walnuts, making them very valuable plants. To harvest, collect the nuts as soon as possible to avoid mold and remove the husks immediately. I had one break a windshield on our car while driving a couple of years ago. I let the squirrels have them. It was an effective way to maintain roads in mud seasons. Black walnut trees are, however, toxic to some species of plants if growing within a certain range of the tree. Butternut nuts have sharper spines on the shells, that’s how I tell the difference. Just cut down the ones you don't want to grow before they get too big. The juglans regia tree (English Walnut Tree) is smooth and soft with fewer ridges while the bark of the juglans nigra (Black Walnut Tree) is hard and grooved. If the husk is completely rotted, we wouldn’t recommend keeping that nut, as the nut will have been left exposed to fungi and pests that could have penetrated the shell. This substance is also found in the tree’s leaves and fruit husks. Submitted by Linda Hamilton on September 28, 2020 - 11:15am. Squirrels have built tribes surrounding it. Thud! When the nuts drop, the go 'splack!' Submitted by Cindy on August 21, 2020 - 3:11pm. I have 3 very old trees in my yard and was thinking of getting rid of some. I plan to buy more taps and tap more trees next spring. Besides collecting the walnuts, we also tap our black walnut trees to make syrup. Those were good memories! We all knew this was stain and not dirt, so no one cared. As an antioxidant, vitamin E protects lipids from oxidation. Both kinds of walnuts are similar in taste and appearance. Submitted by The Editors on September 1, 2020 - 1:56pm. They are messy, dangerous and delicious! The black walnut meets 3 percent of the daily value for vitamin E in an ounce, while the English walnut only meets 1 percent. I have a very large one towering over my garden and my neighbours garden from 2 doors over in the beaches area of Toronto. Black walnuts require a deep, fertile soil with a near-neutral or slightly acidic pH. I have 3 large Black walnuts near where my driveway meets the street (neighbors have others, also near the street). We do love / hate them! Good to know that the tree cover will remain for potentially another 100 years. His Dr. said he had never seen anything like it! They do not yield as much as maple trees, but since I have no maples but plenty of walnuts, I'll happily make due with what I have. I’m amazed at the 250 year potential age. That's why most walnuts that you find at the store still in their shell are common walnuts. BEWARE THE HULLS!!! Yes we went to school with stained hands but so did other kids. They commonly grow to 50 feet or taller and about as wide, but specimens of more than 100 feet have been recorded. My tree is right by my driveway which makes a pretty big mess. The sweet, earthy nutmeat inside is well worth the effort. It is one of the most valuable and fully utilized natural forest trees … Juglone does serve a purpose, though. These trees are sometimes confused due to a similar shape to their compound leaves, and propensity to grow in sunny, disturbed habitats around human habitation, but they are easily distinguished if you know what to look for. In a small Northeast Central Indiana town we have a Black Locust, a Black Walnut & an Ash in a row between two houses. I have a black walnut tree in my backyard. Its super beautiful and provides a nice shady cover for the hot Mid-Atlantic summers. I'd rather be eaten alive by fire ants than to ever buy another house with them anywhere near it. They are toxic to horses! We have a lot of them here in central Pennsylvania and all the comments, pro and con, are true! They also knew it was because we were doing our part to help the family. A hot pepper plant is also doing well, as are two elderberry bushes I just got this year.
