Plants to Avoid Planting with Sweet Potatoes
When planning a garden, it is important to consider which plants should not be planted together. Some plants can inhibit the growth of others or attract pests that can damage neighboring plants. Here are two plants that should not be planted with sweet potatoes:
Potatoes and sweet potatoes are both root vegetables, but they should not be planted together. They are susceptible to the same pests and diseases, and planting them together can increase the likelihood of an infestation. In addition, sweet potatoes can release a chemical that inhibits the growth of potatoes, which can lead to stunted or malformed tubers.
Tomatoes and sweet potatoes should also not be planted together. Like potatoes, tomatoes are also susceptible to the same pests and diseases as sweet potatoes. In addition, planting them together can lead to competition for nutrients, which can result in smaller yields for both crops.
It is best to plant sweet potatoes with plants that complement their growth, such as beans, marigolds, nasturtiums, alyssum, yarrow, and spinach. These plants can help to repel pests and attract beneficial insects, which can improve the health and yield of sweet potatoes.
Benefits of Companion Planting with Sweet Potatoes
Companion planting is a gardening technique where different plants are grown together to enhance their growth and health. When it comes to sweet potatoes, companion planting can offer numerous benefits. Here are some benefits of companion planting with sweet potatoes:
1. Nitrogen Fixation
Sweet potatoes require a lot of nitrogen to grow, which can deplete the soil of this essential nutrient. However, planting nitrogen-fixing legumes like peas alongside sweet potatoes can help replenish the soil with nitrogen. This is because legumes have a symbiotic relationship with bacteria that convert atmospheric nitrogen into a form that plants can use.
2. Pest Control
Companion planting can also help control pests and diseases that affect sweet potatoes. For example, planting aromatic herbs like thyme, oregano, and dill near sweet potatoes can repel pests like sweet potato weevils. Similarly, planting marigolds can deter nematodes that attack sweet potato roots.
3. Improved Soil Health
Companion planting can improve soil health by increasing biodiversity and promoting the growth of beneficial microorganisms. For example, planting cover crops like clover or vetch alongside sweet potatoes can help suppress weeds and improve soil structure.
4. Increased Yield
Companion planting can also increase the yield of sweet potatoes by attracting beneficial insects like bees and butterflies. These insects can help pollinate the sweet potato flowers, leading to more fruit development and a higher yield.
Overall, companion planting can offer numerous benefits when growing sweet potatoes. By choosing the right companion plants and planting them strategically, gardeners can help improve the growth, health, and yield of their sweet potato plants.
