Mimic nature in your garden, and give your vegetables the best possible tools to grow through companion planting. Companion planting is an outstanding way to improve your garden’s health and fruitfulness. When you plant compatible plants near each other, they can mutually benefit from each other’s attributes. Planting different types of plants close to each other can boost growth, repel pests, and even improve the flavor of your harvest.

Benefits of Companion Planting (1)

In addition to the benefits to your plants, companion planting uses your garden space more efficiently, allowing you to harvest more varieties in a given space. The diversity that companion planting provides is also wonderful for pollinators, wildlife, and overall soil health. Discerning what works well together well and how certain plants can bolster others can greatly improve the productivity in your garden. Check out the benefits of companion planting and how it can make a difference in your garden.

Saves Space

We all want to get the most out of the garden space that we have. Save valuable garden space by planting a vining plant under a taller one, utilizing space that would otherwise remain empty. You can also plant quick-growing crops in between rows of slower growing crops for more efficient gardening.

Adds Shelter and Shade to Other Plants

Planting tall, sturdy plants with climbers can provide natural supports within your garden, eliminating the need for building separate structures and staking. Vertically friendly plants like corn and sunflowers can support lower-growing, climbing crops such as beans, cucumbers, and peas. Tall crops can also provide protective shade for plants that don’t require as much intense sun.

Useful to Attract Favorable Insects

There are a lot of insects that are extremely beneficial to gardens, and a wide variety of plants can increase the chances that they visit often. Butterflies, bees, and birds are essential pollinators for your garden’s healthiest growth. Also, these happy insects are the best kind of pest control for your treasured plants. A diversification of plants and flowers with extended and varying blooming periods are sure to keep beneficial insects continuously visiting your garden.

Helps the Soil

Planting different plant types together can help keep your soil moist and prevent erosion then. Open soil patches would be a waste of valuable garden space. Plants like cucumber and squash do a wonderful job shading the soil. Shading soil can be useful in times of drought. Some vegetable plants improve the soil quality of other plants. For example, beans help to restore nitrogen into the soil as they grow.

A perfect example of this is the Nasturtium. The nasturtium plant is adored by the highly destructive pest, the aphid. Through smart companion planting, you can purposefully use the nasturtium plant as a host and sacrifice them to help protect nearby plants that are bothered by aphids.

Adds Continuous Beauty to the Garden

Vegetables aren’t the only plants that can benefit from companion planting. The benefits of companion planting can also be purely aesthetic. When you mix annuals and perennials or plants with varying bloom times, it is possible also to have your garden in a state of continuous bloom.

  2. The idea of using one plant next to another to keep bugs away makes me very happy. Specifically, what can I plant to keep squash borers and stink bugs out of my garden? Any suggestions?

    Reply

    • Hi LBB, for both squash borers and stink bugs, you can try using marigold, bee balm, mint, catnip, radishes, tansy, and nasturtium. However, be sure to keep an eye on your plants and pick off any pests as soon as you spot them.
