When it comes to planting potatoes, it’s important to consider the companions that should be avoided. While regular potatoes are versatile and can be paired with many different plants, there are a few that may not be the best companions due to the risk of similar diseases. Let’s explore some plants that you should not plant near potatoes:
1. Tomatoes: As surprising as it may sound, tomatoes and potatoes are part of the same plant family, Solanaceae. This family includes other nightshade plants like peppers and eggplants. Planting tomatoes near potatoes increases the risk of diseases such as blight, which can affect both plants. To prevent cross-contamination, it’s better to separate them.
2. Eggplants: Similar to tomatoes, eggplants belong to the Solanaceae family and are susceptible to similar diseases. Planting them near potatoes can increase the risk of fungal infections and pest infestations that affect both crops. To ensure the health of your plants, it’s best to keep them separate.
3. Peppers: Peppers, including bell peppers, chili peppers, and sweet peppers, also belong to the Solanaceae family. They are prone to similar diseases as potatoes, such as late blight and early blight. To minimize the risk of spreading diseases, it’s advisable to plant peppers away from potatoes.
4. Other Solanaceae family members: Aside from tomatoes, eggplants, and peppers, there are other plants in the Solanaceae family that should be kept away from potatoes. This includes plants like tomatillos and ground cherries. These plants can share diseases and pests with potatoes, leading to reduced yields and compromised plant health.
5. Cucumbers: While cucumbers do not belong to the same family as potatoes, they are best kept separate due to their different growth habits. Cucumbers are vigorous climbers, and when planted near potatoes, they may shade and compete for resources, affecting the overall growth and yield of both crops. To ensure optimal growth, it’s better to give each plant its own space.
6. Squash and pumpkins: While potatoes and squash/pumpkins may not necessarily harm each other, they have different growth habits and space requirements. Planting them together can result in overcrowding and reduced airflow, which can promote the development of diseases such as powdery mildew. To give both plants ample space to thrive, it’s best to separate them.
Remember, these guidelines are not set in stone, and there may be exceptions depending on your specific garden conditions and practices. However, keeping these plants separate from potatoes can help minimize the risk of diseases, pests, and competition for resources, ensuring healthier and more productive plants overall.
