Every person who plants a garden wants their crops to flourish! No one wants to spend time, money, and effort on a garden and watch it wither and wilt within the first few weeks. Companion plants can be a HUGE help to your garden crops. Not only can companion plants aid in your crop growth and quality, they can also deter pests while welcoming helpful insects! Companion plants allow you to maximize your gardens’ potential and crop yield.

In this post, we will look at common, easy beginner crops and companion plants that are beneficial, as well as plants to avoid!

Below, you will find a helpful table that outlines ideal companion plants and “enemy” plants- this will be very helpful when planning the layout of your garden! You want to be sure that you are not planting enemy plants together as it will affect the growth and quality of your crops.

Since this is only a brief look at some common garden crops, you will not find a list of every possible plant combination. If you are planting something that is not on the table below, you can easily find recommended companion plants online.

Also, note that some companion plants can be herbs or flowers! Herbs are fantastic plants to grow since most do not require a lot of maintenance, they grow quickly and abundantly, and you can use them to spice up many recipes!  Also, using flowers as companion plants can really add some color and beauty to your vegetable garden.  Thinking of growing some tomatoes? Grow some basil and oregano, too! The oregano is beneficial to cucumbers and squash and the basil helps to repel flies and mosquitoes and together they make an excellent addition to homemade tomato sauce :) Want to make some refreshing mojitos this summer? Grow some mint and enjoy the crisp, tasty goodness that accompanies fresh ground mint leaves!  Just be sure to plant it next to tomatoes or squash to take advantage of its beneficial properties.

There are SO MANY possibilities to make your garden work for YOU so you can enjoy the harvest!
