Companion Plant Chart:

Companion planting is a time-tested method where certain plants help each other thrive — boosting growth, repelling pests and improving flavour. In this easy-to-use chart, you'll find the best and worst plant pairings for all your garden favorites. Whether you're planning a small kitchen garden or a full backyard plot, understanding companion planting can help make a difference.
For pest control I use herbs and flowers.

General Tips:

• Nutrient Balance: Some plants, like beans, fix nitrogen in the soil, which can benefit neighboring plants.
• Pest Control: Plants like marigolds, calendula, nasturtiums, thyme, chives, dill and garlic, act as natural pest repellents.
• Space Management: Companion plants should complement each other in terms of space, with some providing shade and structure.
