What Not To Plant With Leeks

When it comes to planting leeks, it’s important to consider what not to plant alongside them. One such group of plants to avoid is alliums. Alliums include onions, garlic, and chives, and they can have a negative impact on the growth and development of leeks.

Alliums and leeks belong to the same family, the Alliaceae family, and they can compete for nutrients and space in the garden. This competition can result in stunted growth and reduced yields for both plants. Additionally, alliums are known to attract pests such as onion flies, which can further damage the leeks.

Leeks prefer a slightly acidic soil pH, while alliums thrive in a more alkaline soil. Planting them together can create an imbalance in the soil pH, making it less than ideal for both plants. It’s best to keep these two groups of plants separate to ensure optimal growth and productivity.

In addition to alliums, there are a few other plants that should not be planted with leeks. One such plant is potatoes. Potatoes and leeks have similar nutrient requirements, and planting them together can lead to competition for these nutrients. This can result in reduced yields for both crops.

Another plant to avoid planting with leeks is beans. Beans are nitrogen-fixing plants, meaning they have the ability to convert atmospheric nitrogen into a form that plants can use. While this may sound beneficial, it can actually lead to an excess of nitrogen in the soil, which can negatively impact the growth of leeks.

Furthermore, it’s best to avoid planting leeks near brassicas, such as cabbage and broccoli. Brassicas are heavy feeders and can deplete the soil of nutrients that leeks need to thrive. Additionally, brassicas are susceptible to similar pests and diseases as leeks, which can increase the risk of infestations and infections.

By keeping these plants separate, you can ensure optimal growth and productivity for your leeks.
