Companion Planting

What is Companion Planting?

Companion planting is important in vegetable gardening. It involves growing different plant species together in a mutually beneficial manner. This practice is important for several reasons:

Pest control: Certain plants act as natural insect repellents or deter critters. For example, marigolds release a scent that can deter insects, thus protecting nearby plants. Garlic is another good example.  Its smell is not appealing to many pests. By planting garlic as a barrier, you can protect other plants from attack.

Soil health: Certain plants can improve soil health by adding nutrients or fixing nitrogen in the soil, benefiting other plants nearby. For example, beans and peas help make nitrogen more available.

Space optimization: By planting taller plants near shorter ones, you can optimize space and create a more efficient garden layout.  Tall plants like sunflowers and corn can support lower-growing, vining crops, such as cucumbers, pole beans, and peas. This mutual support benefits both plant types. Plus, large plants provide shade for smaller ones that need sun protection. For instance, corn can shade lettuce.

Beneficial insects

Some plants attract beneficial insects, like bees for pollination and tiny pest-eating wasps.

Aesthetic appeal: Companion planting can create visually appealing gardens with a variety of colors and textures.

In summary, companion planting allows you to grow more, healthier vegetables by optimizing space and resources. When compatible plants are grown near each other, they mutually benefit from each other's attributes, leading to a more bountiful harvest. So, consider these plant friendships when planning your vegetable garden.
