Practice Crop Rotation

Avoid planting the same crop family in the same garden bed for at least three to four consecutive years. Move tomatoes, peppers, and potatoes (all Solanaceae) to a different location each season, and do the same for cucurbits, brassicas, and legumes. This simple planning step is one of the most effective defenses against recurring plant diseases.

Why It Works

Many fungal, bacterial, and nematode pathogens overwinter in soil and plant debris. When the same host crops return to the same spot year after year, pathogen populations build up to damaging levels. Rotation starves those pathogens by removing their preferred host.

Tips

• Keep a simple garden map each year so you can track what grew where
• Group crops by botanical family when planning rotations
• Follow heavy feeders (tomatoes) with soil-builders (legumes) to improve overall bed health
• If space is limited, even a two-year rotation is better than none
