5 Plants Not To Pair With Peaches & Why

Although many different plants are ideal for growing under or near your peach trees, there are several you’ll want to avoid for best results.

1. Tomatoes

Tomatoes are very sensitive to nematodes. Besides, they can spread blight, which will eventually make your peach tree decay.
