Avoid Planting a Garden Near a Black Walnut Tree
As trees start losing their leaves, it’s important to be aware of certain species that can cause damage to your lawn. There’s one popular tree, specifically, to watch out for. In today’s blog, Nixa Lawn Service provides information about the Missouri Black Walnut, aka the “killer tree.”
About Black Walnuts
Black Walnut has been labeled as Missouri’s official state tree nut. The trees are tall and large, with straight trunks and wide canopies. Black Walnut wood is often used for furniture, while the nuts are used for baking purposes. The wood from this species is truly splendid, and thus it is often in demand.
For many Missourians, black walnuts are abundant and beneficial. After all, they provide shade, tasty nuts, and wind protection. The moderate weather and soil types of the Ozarks are suitable for this native crop. But despite the positives, these trees are fickle and present some hazards.
What Makes Black Walnut Trees So Bad?
In fact, it’s not really the trees themselves that are bad, but rather a harmful compound they produce. Black Walnuts produce a compound called juglone in their leaves, fruit, bark and roots, which is released into nearby soil. This compound may then cause serious damage to many plants, such as tomato and pepper crops. In fact, it can even kill them. Among all species of the walnut family, Black Walnut has the highest concentration of juglone.
If you have Black Walnut trees on your property, note that the juglone from falling nuts and leaves may impact other vegetation planted nearby. Consider an alternate spot for your vegetable garden.
Tips and Things to Look Out For
The symptoms of juglone include plant leaves turning yellow, wilting, and eventually dying. If your plant still wilts after you’ve ensured that sufficient soil moisture is present, look for nearby Black Walnut Trees. Anything within a 50-foot radius, called the drip line, is considered the toxic zone. This harmful area may extend outwards as the tree grows older.
It is important to know that Walnut Tree materials can be composted. The juglone compound is broken down when it’s exposed to water, bacteria and air. You can cause the juglone to break down sufficiently by composting for at least six months.
You may want to entirely remove Black Walnut trees from your area. However, be aware that decaying roots still release juglone. Even years after a tree is removed, the toxicity can continue.
