How to Grow Squash and Beans Together (Companion Planting)

Companion planting is a gardening technique that can be used to improve the health and yield of plants. By growing two or more plants together, you can take advantage of each other’s benefits.

For example, squash and beans can be grown together because the beans will fix nitrogen in the soil, which will benefit the squash.

What Is Companion Planting?

The basic idea of companion planting is to choose plants that will benefit each other. This can be done in several ways:

  1. One plant may provide nutrients that another plant needs. For example, beans fix nitrogen in the soil, which other plants can use.
  2. One plant may attract beneficial insects, which can help to protect another plant from pests. For example, marigolds release a chemical that repels some garden pests.
  3. One plant may provide shade or support for another plant. For example, tall plants like corn can provide shade for shorter plants like lettuce.

As you can see, there are many potential benefits to companion planting. However, in order to choose the right plants to grow together, it is important to consider what each plant needs and how they can help each other.

Squash is a cucurbit family member, including cucumbers, watermelons, and pumpkins. There are many different varieties of squash, including zucchini, summer squash, and winter squash.

Beans are a type of legume, which is a plant that produces its seeds in pods. Common types of beans include lima beans, black beans, and kidney beans.

The Benefits of Companion Planting Squash and Beans

As mentioned earlier, one benefit of growing squash and beans together is that the beans will fix nitrogen in the soil. This is important because squash is a heavy feeder and needs a lot of nitrogen to grow well.

In addition, the beans will also provide support for the squash plants. The vines of some squash varieties can get quite long, and the beans can help to keep them off the ground.

Finally, companion planting squash and beans can also help to deter pests. The beans’ strong smell will help keep pests away from the squash plants.

How to Grow Squash and Beans Together

Now that you know some of the benefits of growing squash and beans together, let’s talk about how to do it.

When growing squash and beans together, it is important to plant them at the right time. The best time to plant squash is in late spring or early summer after all danger of frost has passed. The best time to plant beans is about a week after the squash.

When choosing a location for your garden, choose an area with plenty of sunlight. For example, squash and beans need at least six hours of sunlight daily.

Prepare the soil by adding organic matter, such as compost or manure. This will help to improve drainage and provide nutrients for the plants.

You will also need to choose the right varieties of squash and beans. For the squash, look for bush varieties like ‘Early Prolific Straightneck’ or ‘Pattypan’. For the beans, look for pole varieties like ‘Blue Lake’ or ‘Kentucky Wonder’.

When planting, make sure to space the plants correctly. For example, squash plants should be spaced about 2-3 feet apart, and bean plants should be spaced about 1 foot apart.

Once the plants are in the ground, water them well and fertilize them according to their needs. Be sure to check for pests and diseases, and treat them accordingly.

Another example is the “three sisters” planting. This is a Native American tradition where corn, beans, and squash are planted together. The corn supports the beans, and the beans provide nitrogen for the soil to help the corn grow well. The squash helps to keep away pests from both the corn and beans.

Harvesting Tips for Both Squash and Beans

Squash and beans are both ready to harvest when their fruits are mature. For squash, the skin is hard, and the fruit is firm. For beans, this means that the pods are plump and have turned from green to yellow or brown.

Cut the fruit from the plant with a sharp knife to harvest squash. To harvest beans, snap the pods from the plant.

Both squash and beans can be stored in a cool, dark place for later use.

When harvesting squash and beans together, it is important to remember that they should not be stored together. This is because beans release ethylene gas, which can cause the squash to spoil more quickly.
