Can I Plant Tomatoes Near English Walnut Trees?

English walnut trees are known for their large, delicious nuts and stately appearance in the landscape. However, they also have a reputation for being difficult to plant around due to their allelopathic properties. Allelopathy is the process by which plants release chemicals that can inhibit the growth of other nearby plants. This leaves many gardeners wondering whether they can plant tomatoes near English walnut trees.
