What to plant after tomatoes
After tomatoes, plant anything outside the nightshade family: beans and peas, cabbage family crops such as kale or broccoli, onions and garlic, or roots such as carrots and beets.
Do not follow tomatoes with potatoes, peppers, eggplant or tomatillos. Check a bed below.

Why legumes are a common next step
Many rotation plans follow a heavy-feeding crop like tomatoes with peas or beans, then a leafy crop. That order is a habit, not a rule: what matters most is keeping nightshades out of the bed for a few years.
A worked example
Your fence bed grew tomatoes in 2026. For 2027 it can take bush beans in spring or summer, or garlic planted this fall. Nightshades can return to the fence bed in 2029.

Yes. Cucumbers are in the squash family, a different family from tomatoes.
