Reduce or eradicate the need for chemical pest control completely with companion planting!
Companion Planting is an intermixing of aromatic flowers and herbs for the mutual benefit of the plant. For instance…planting Marigolds with your tomatoes will deter a number of insects & caterpillars. In addition to reducing (or replacing!) harsh pesticides by planting beneficial plants together, companion planting has been shown to create a higher crop yield.


Some plants release nutrients into the soil, which prevents the need for fertilizers the following season (For example- Legumes release nitrogen into the soil). This method of gardening is a great way to begin organic gardening!

In addition to being a benefit in growth rates and avoiding the use of chemical pesticides, companion planting also has a tendency to improve the flavor and nutrient content of the fruits and vegetables.

For example, planting sunflowers between cucumber plants not only provide the plant with beneficial shade and natural vining material, the sunflowers also absorb the chemical in cucumbers that can create a bitter flavor, resulting in considerably sweeter cucumbers.

You may have heard of “The 3 Sisters”, planting a combination of corn, pole beans and squash.

As the corn grows tall, it provides a natural trellis for the beans. Corn roots tend to grow fairly shallow, while the roots of beans tend to be much deeper, giving the corn added security and strength. The beans produce and deposit nitrogen into the soil naturally, which the corn and squash both require.

Squash naturally provide a mulch to both the beans and corn which helps them to retain moisture (and reduce the need for additional watering). In addition, the leaves of the squash are quite prickly which create a natural deterrent to many animals that might otherwise make a meal of the plants. These types of natural symbiotic relationships are the key to natural, organic gardening.

Here is a chart that shows some common items, what to plant near them (aka Good Companions) and how they help.
