what not to plant with lemongrass

3 min read 22-12-2024

Lemongrass, with its vibrant citrus scent and culinary uses, is a popular herb to grow. However, understanding companion planting—the art of strategically placing plants together—is crucial for a thriving lemongrass patch. This guide explores what *not* to plant with lemongrass to avoid hindering its growth and yield.

Why Companion Planting Matters for Lemongrass

Companion planting can significantly impact a plant's health and productivity. Certain plants can complement each other, offering mutual benefits like pest control or improved nutrient uptake. Conversely, some plant pairings are detrimental, competing for resources or creating unfavorable conditions. Lemongrass, like many herbs, has specific companions to avoid.

Plants to Avoid Planting With Lemongrass

While lemongrass is generally robust, certain plants can negatively affect its growth. Here's a list of plants to avoid planting near your lemongrass:

1. Aggressive Growers

Avoid planting lemongrass near aggressive growers like mint or bamboo. These plants spread rapidly, overwhelming lemongrass and competing for vital nutrients, sunlight, and water. Their vigorous root systems can easily encroach on the lemongrass's space, stunting its growth.

2. Heavy Feeders

Plants that are heavy feeders, requiring a lot of nutrients from the soil, can deplete the resources lemongrass needs to thrive. Examples include members of the brassica family (cabbage, broccoli, cauliflower) and sunflowers. These plants will out-compete lemongrass for essential nutrients, leading to weaker growth and reduced yield.

3. Similar Nutrient Needs

Planting lemongrass alongside plants with similar nutrient requirements can lead to competition. This reduces the availability of essential elements for optimal growth for both plants. Careful consideration of nutrient needs is crucial for successful companion planting.

4. Pest and Disease Prone Plants

Certain plants attract pests or diseases that can also affect lemongrass. If you're already dealing with issues, it's best not to add more vulnerability. It's safer to keep lemongrass away from plants with known pest or disease problems. This minimizes the risk of infestation spreading to your lemongrass.

5. Plants That Don't Respond Well to Citrus

Although lemongrass is known for repelling some pests, some plants are simply sensitive to the strong aroma of citrus and might not thrive in proximity to lemongrass. Observe any signs of distress in nearby plants, and adjust accordingly. If other plants near your lemongrass show signs of wilting or other stress symptoms, consider relocating them.

Ideal Companions for Lemongrass

While avoiding certain plants is crucial, choosing beneficial companions can enhance lemongrass growth. Good companions include plants that attract beneficial insects or improve soil health, such as marigolds and basil.

Optimizing Your Lemongrass Patch

Careful planning and consideration of companion planting can significantly improve the health and yield of your lemongrass. By avoiding unfavorable pairings and choosing beneficial companions, you can create a thriving and productive herb garden.
