What Are Walnut Trees?

Walnut trees are deciduous trees that grow in a variety of climates around the world. They are known for their high-quality wood, as well as the nutritious nuts they produce.

It is best to avoid planting more sensitive vegetables like potatoes, eggplants, and strawberries.

In addition to choosing the right vegetables, it is also important to take steps to minimize the spread of juglone. This may include removing any fallen leaves or nuts from the area, as well as creating a barrier between the tree and the garden using mulch or other materials. Raised garden beds can also be a good option, as they allow for better control over the soil and can help to prevent the spread of juglone.
