Crop Rotation Strategies
If you fail to incorporate effective crop rotation strategies in the vegetable garden, you can experience recurring pests and disease problems that will become greater year after year. It is crucial to establish the right crop rotation strategies to eliminate these problems. Our goal is to not plant the same family of crops in the same spot in consecutive years.
Crops in the Same Family
Travis shows a comprehensive list of vegetables and their respective families. The first family of crops is Solanaceae, commonly known as the nightshades. This family includes popular vegetable crops like tomatoes, eggplants, peppers, and potatoes. Most folks don't realize that potatoes are closely related to the other crops in the nightshade family. As a result, you wouldn't want to plant tomatoes, peppers or eggplant in the same spot as potatoes in a given year. If you are not careful to rotate these crops, you will almost certainly experience some blight issues that will intensify over time.

The next family is Cucurbitaceae, also known as the Cucurbits. This family includes crops like summer squash, winter squash, pumpkins, cucumbers, watermelons, cantaloupes, and gourds. All of the crops in the Cucurbit family can have issues with powdery mildew and downy mildew, so rotating these crops ensures those disease problems will not increase year after year. Cucurbits also tend to have high insect pressure with pests like squash bugs, squash vine borers and pickle worms.

The next family is the Brassicas, which is one of the most popular families of crops grown in the vegetable garden. The brassica family includes mustards, cauliflower, cabbage, broccoli, kohlrabi, bok choy, rutabagas, turnips, and radishes. Brassicas can have recurring pest issues if not rotated properly, especially with worms that will chew and eat the plant leaves.
