What Should Not Be Planted Near Kohlrabi?

When planning your garden layout, it’s essential to consider the relationships between different plants. Certain plants thrive together, while others can hinder each other’s growth. In the case of kohlrabi, there are specific plants that should not be planted near it to ensure its optimal health and yield.

One key factor to consider is the susceptibility of kohlrabi to pests such as aphids, flea beetles, cabbage worms, and loopers. These insects are attracted to kohlrabi plants and can cause damage to them. By avoiding planting certain plants near kohlrabi, you can help minimize the presence of these pests in your garden.

Members of the cabbage family, including cabbage, broccoli, cauliflower, and Brussels sprouts, should not be planted near kohlrabi. These plants are closely related to kohlrabi and are susceptible to similar pests. By planting them together, you may inadvertently create a more attractive environment for pests, leading to potential infestations.

Additionally, planting other root vegetables in close proximity to kohlrabi is not recommended. Root vegetables like carrots and radishes can compete with kohlrabi for nutrients in the soil, potentially stunting its growth and overall development. To ensure that your kohlrabi plants have access to the nutrients they need, it’s best to keep them separate from root vegetables.

Legumes such as beans and peas should also be avoided near kohlrabi. These plants have different nutrient requirements and growth habits compared to kohlrabi, which can lead to competition for resources and limited space for each plant to thrive. By planting them separately, you can give both kohlrabi and legumes the best chance to grow successfully.

Herbs like dill and mustards should be kept away from kohlrabi as well. While some herbs can have beneficial effects on certain plants, dill and mustards have allelopathic properties that can inhibit the growth of nearby plants, including kohlrabi. To prevent any negative interactions, it’s best to plant herbs like dill and mustards in a separate area of the garden.

In addition to specific plant types, it’s essential to consider the spacing between kohlrabi and other plants. Overcrowding can lead to increased competition for sunlight, water, and nutrients, which can negatively impact the overall health of your kohlrabi plants. Providing adequate space between kohlrabi and neighboring plants is crucial for their successful growth.

Furthermore, considering the growth habits of neighboring plants is important when deciding what to plant near kohlrabi. Plants that have sprawling or invasive roots can overshadow and outcompete kohlrabi, limiting its access to essential resources. Choosing companion plants with similar growth habits can help create a harmonious environment for all your garden crops.

It’s also worth noting that certain plants can have allelopathic effects on kohlrabi, releasing chemicals that inhibit its growth and development. Avoid planting crops like sunflowers and walnuts near kohlrabi, as these plants are known to have allelopathic properties that can negatively impact the growth of neighboring plants.

When planning your garden layout, consider the overall compatibility of different plant species and their potential impact on the health and growth of your kohlrabi plants. By avoiding planting certain plants near kohlrabi and paying attention to spacing and growth habits, you can create a thriving garden ecosystem that supports the optimal growth of all your crops.

Ultimately, understanding the relationships between different plants and making informed decisions about your garden layout can help you cultivate a diverse and healthy garden with flourishing kohlrabi plants.
