Companion planting is the practice of growing certain plants together to benefit one or both in some way and one of the fundamentals of permaculture. It’s based on the idea that certain plants help others grow better, deter pests, drastically improve biodiversity, improve flavor or make better use of space. It's a natural way to support a healthy gardens ecosystem.
Plus biodiversity is key to any successful garden. "Grow food, not lawns"..
Monoculture isn't just boring, but also bad for many ecosystems as it goes against nature, which even to a child is inherently problematic..
Here are a few of my recommendations:
Tomatoes and basil: Basil is thought to enhance tomato flavor and may help repel pests like aphids and whiteflies.
Carrots and onions: Onions can help deter carrot flies, while carrots don’t interfere with onion growth.
Corn, beans, and squash (The Three Sisters): A traditional Native American trio-corn provides a structure for beans to climb, beans fix nitrogen in the soil, and squash shades the ground to suppress weeds.
Marigolds and many vegetables: Marigolds repel nematodes and other pests, making them great general companions.
However, not all combinations are good. For instance:
Onions and beans don’t do well together, as onions can stunt bean growth.
Tomatoes and corn can attract the same pests and compete heavily for nutrients..
Although yields of some crops may be slightly reduced, the resulting benefits to your gardens health, more than make up for it..
