When deciding what to plant after potatoes, there are several factors to consider, including crop rotation, timing, and nutrient depletion. Crop rotation is a key strategy for reducing pest and disease problems, as well as nutrient depletion. The following are some options for what to plant after potatoes:

Plants to Grow After Potatoes:

• Peas or green beans: These legumes or beans will add nitrogen to the soil, which will improve the nutrient level for the next vegetables to grow in that area.
• Shallow-rooted fruit and vegetables: Such as strawberries and spinach, are perfect potato companions.
• Cover crops: Buckwheat, alfalfa, or annual ryegrass can improve the structure and fertility of the soil.

Plants to Avoid Planting After Potatoes:

• Other root crops: Such as carrots or beets, as they will compete for space underground.
• Other members of the nightshade (Solanaceae) family: Such as tomatoes, peppers, and eggplants, as they are all susceptible to the same diseases and pests.

It is also important to keep in mind the timing of planting and harvesting, as well as the nutrient needs of the plants being grown. Following a crop rotation plan can help ensure a healthy and productive garden.
