Are marigolds good companions to runner beans?
Marigolds are popular in New Zealand gardens for their vibrant blooms and pest-repelling qualities. But do they make good companions to runner beans? In this guide, we explore the benefits and potential drawbacks of planting marigolds alongside runner beans specifically in New Zealand. This article will provide you with everything you need to know about companion planting marigolds and runner beans in your Kiwi garden.
The Benefits of Companion Planting
Companion planting involves growing different plants together to enhance growth, deter pests, and improve yields. Marigolds are often recommended as companion plants due to their ability to repel harmful insects and improve soil health. But how do they benefit runner beans specifically in New Zealand?
Marigolds and Pest Control
Firstly, marigolds are excellent at repelling pests. Their strong scent deters aphids, nematodes, and other insects that can harm your runner beans. By planting marigolds near your runner beans, you create a natural barrier against these pests. This reduces the need for chemical pesticides, making your garden more eco-friendly.
Soil Health Improvement
Marigolds also contribute to soil health. They produce compounds that can suppress harmful nematodes in the soil. These nematodes can damage the roots of runner beans, leading to stunted growth and reduced yields. By planting marigolds, you help create a healthier environment for your runner beans to thrive in New Zealand’s unique climate and soil conditions.
Enhanced Pollination
Another benefit of planting marigolds with runner beans is enhanced pollination. Marigolds attract beneficial insects like bees and butterflies, which play a crucial role in pollinating runner beans. Better pollination leads to more flowers and, ultimately, a higher yield of beans. This is particularly valuable in New Zealand, where promoting pollinator activity is essential for garden productivity.
Potential Drawbacks
While marigolds offer many benefits, it’s essential to consider potential drawbacks. Marigolds can sometimes attract slugs and snails, which may harm your runner beans. To mitigate this, use slug traps or barriers to protect your plants. Additionally, ensure proper spacing between marigolds and runner beans to avoid competition for nutrients and sunlight.
Planting Tips for Success
To maximize the benefits of companion planting in New Zealand, follow these tips:
- Choose the Right Varieties: Select marigold varieties known for their pest-repelling properties, such as French marigolds (Tagetes patula).
- Proper Spacing: Plant marigolds at the ends of your bean rows or intersperse them with runner beans to ensure adequate spacing and sunlight.
- Watering and Maintenance: Maintain consistent watering and mulching to keep the soil healthy and moist. Deadhead marigolds regularly to encourage continuous blooming.
Conclusion
In conclusion, marigolds make excellent companions to runner beans, offering numerous benefits such as pest control, improved soil health, and enhanced pollination. By following the planting tips provided, you can create a thriving and productive garden in New Zealand. Happy gardening!
