Companion planting | Colour Dots Companion planting

Gardening can be filled with all sorts of complications. It is always subject to the whims of weather, insects, or fungal infections. Companion planting can help avoid some of these issues. Ensuring your yield from your backyard garden is optimal, consider some of these ideas.
Here are some ideas which can mitigate some of the vagaries of food gardening.
The best way to find some success is to plant smaller crops in bigger varieties. Avoid planting the same crop season after season in the same place.
There are plants that thrive when planted close to each other and some that just do not.

How Companion Planting Works

Nutrients

Plants take up nutrients from the soil and also return minerals to the growing medium. These differ from plant to plant. It is important to look for a balance. This is why crop rotation is essential for good results.
Legumes such as beans and peas return more nutrients than they take. These plants have a symbiotic relationship with nitrogen-fixing microbes. These microbes absorb the sugars produced by the roots in order to capture nitrogen and convert it into a form that is available for plants.

Scents

Only a few insects are true enemies of gardeners. Some plants attract insects and some repel them. Plants that have strong scents such as mint, basil, marigolds and garlic can keep pests at bay.

Shelter.

Gardeners always welcome beneficial insects and it is an idea to provide for these friends. Basil borage thyme and other herbs attract beneficial insects Ladybugs like to snack on aphids. They are often found on roses where aphids can be a problem.

Spiders prey on many of a gardener’s enemies. Plants that have a lot of pollen will provide shelter and food for helpful insects.

Traps

Pests can often be lured away from your crops when you plant a sacrificial plant nearby. Nasturtiums often can work to attract nasties away from your food crops.

Planning

You can plant tall sun-loving plants alongside shade-tolerant species. For example, maize can shelter low-growing plants like squash. You can also allow climbers such as beans to grow up the maize plant as it grows taller.
