Understanding the Importance of Companion Plants

Companion planting is rooted in the concept of permaculture, where plants are grown in a way that mimics natural ecosystems. When different plants are placed together strategically, they can create a harmonious environment that supports the growth and health of each other. This practice also reduces the need for chemical pesticides and fertilizers.

For tomatoes specifically, companion plants can help deter pests, improve pollination, enhance flavors, and provide shade or support. By choosing the right companions, you can create a more diverse and balanced garden ecosystem, ensuring a higher yield of healthy tomatoes.

The strong scent of chives masks the scent of your tomato plants, making them less attractive to pests. Plant chives around your tomato plants to provide natural protection.
