Benefits of Planting Calendula with Other Plants
Planting calendula alongside other flowers and herbs can have some wonderful benefits, including repelling pests and attracting beneficial insects to your garden. Let’s explore how this versatile herb can enhance the health of your entire garden ecosystem.
Improving Soil Health and Fertility
When you plant calendula with other crops, one of its most significant benefits is its ability to improve soil health and fertility. This is largely due to the deep taproots that calendula develops as it grows. Unlike many other plants that have shallow roots, calendula’s extensive root system allows it to tap into nutrients in the subsoil that would otherwise be unavailable to other crops.
As a result of this unique characteristic, calendula acts like an underground “nutrient pump,” bringing up essential minerals and micronutrients from deep within the soil. These nutrients are then released back into the surrounding soil as the plant grows, enriching the soil for nearby plants to benefit from. This can lead to a range of positive outcomes, including healthier soil microbial activity, improved water retention, and increased fertility.
By incorporating calendula into your companion planting scheme, you can reduce your reliance on fertilizers and create a more balanced ecosystem in your garden. Simply plant calendula among your other crops, and watch as it helps to create a richer, more productive growing environment over time.
Enhancing Pest Resistance through Biodiversity
When you grow diverse companion plants alongside calendula, you create a balanced ecosystem that discourages pests and diseases. This is because each plant has its unique characteristics, such as attracting beneficial insects, repelling pests, or improving soil health.
For instance, planting marigolds near calendula can repel nematodes, microscopic worms that feed on the plant’s roots. Similarly, basil repels aphids and whiteflies, which are common pests of calendula. Borage, with its tall spikes of blue flowers, attracts beneficial pollinators like bees and butterflies, while its taproot helps break up compacted soil.
Growing a mix of annuals and perennials also promotes biodiversity in your garden. Annuals like nasturtiums and calendula bloom quickly, attracting pests that might otherwise target the more delicate perennials like lavender or rosemary. By creating this balanced ecosystem, you can reduce the need for pesticides and maintain healthier plants.
As a bonus, many of these companion plants are edible or have medicinal properties, adding an extra layer of value to your garden.
