Can Potatoes Be Planted After Tomatoes?

Potatoes and tomatoes are both members of the same plant family, Solanaceae, which may make people wonder whether potatoes can be planted after tomatoes have been harvested. The answer is yes, but there are a few things to keep in mind when planting potatoes after tomatoes.

Soil Rotation

One of the most important things to consider when considering planting potatoes after tomatoes is soil rotation. Potatoes are highly susceptible to soil-borne diseases such as scab, and planting them in soil that previously hosted other members of the Solanaceae family can increase the risk of these diseases affecting the potato crop. This is why it is important to rotate crops and avoid planting potatoes in soil that has recently hosted tomatoes or other members of the Solanaceae family.

Soil Preparation

Before planting potatoes after tomatoes, it is important to properly prepare the soil. Potatoes require well-draining soil that is rich in organic matter. To prepare the soil, remove any remaining tomato plants and debris from the soil. Then, add compost or other organic matter to improve soil fertility and structure. It is also a good idea to conduct a soil test to determine the nutrient levels in the soil and determine if any amendments are needed.

Planting Potatoes

After preparing the soil, it is time to plant the potatoes. Potatoes can be planted in rows or in hills. If planting in rows, space the rows about 30 inches apart and plant the seed potatoes about 12 inches apart within the rows. If planting in hills, space the hills about 3 feet apart and plant three to four seed potatoes in each hill. The seed potatoes should be planted about 4 inches deep.

Caring for Potatoes

Once the potatoes have been planted, it is important to provide them with the care they need to grow and produce a healthy crop. This includes watering the plants regularly, providing them with adequate sunlight, and fertilizing the soil as needed. It is also important to monitor the plants for signs of disease or pest infestation and take appropriate action if necessary.

Harvesting Potatoes

Potatoes can be harvested when the leaves of the plants begin to turn yellow and die back. Carefully dig up the potatoes using a garden fork, being careful not to damage the tubers. After harvesting, allow the potatoes to dry in the sun for a few days before storing them in a cool, dry place.

Conclusion

While it is possible to plant potatoes after tomatoes, it is important to take precautions to ensure that the potato crop is not affected by soil-borne diseases. Proper soil preparation, planting techniques, and care can help ensure a successful potato crop after tomatoes have been harvested.
