Vegetables Not to be Planted Together


Gardening is a wonderful activity that allows you to grow your own fresh produce. However, not all vegetables are meant to be planted together. Certain combinations can hinder growth, attract pests, or even spread diseases. To ensure a successful and healthy garden, it is important to know which vegetables should not be planted together.


1. Why should I avoid planting certain vegetables together?

Planting certain vegetables together can lead to competition for resources such as water, sunlight, and nutrients. It can also attract pests that prefer specific vegetables, resulting in a higher risk of infestation. Furthermore, some plants release substances that can inhibit the growth of nearby vegetables.

2. Which vegetables should not be planted together?

Here are some examples of vegetables that should not be planted together:

3. Tomatoes and Cabbage

Tomatoes and cabbage both require a lot of space and nutrients. When planted together, they can compete for these resources, leading to stunted growth. Additionally, tomatoes can attract pests that may also damage cabbage plants.

4. Carrots and Onions

Carrots and onions have different root structures and growth patterns. When planted together, they can interfere with each other’s growth. Onions can also deter pests that may attack carrots, making them a beneficial companion plant when grown separately.

5. Beans and Onions

Beans and onions should not be planted together as beans are heavy feeders and require high amounts of nitrogen. Onions, on the other hand, do not tolerate high levels of nitrogen and may suffer from stunted growth or disease when grown in close proximity to beans.

6. Potatoes and Tomatoes

Both potatoes and tomatoes belong to the nightshade family and are susceptible to similar diseases, such as late blight. Planting them together increases the risk of spreading diseases and can lead to significant crop loss.

7. Cucumbers and Sage

Sage is known to inhibit the growth of cucumbers. When planted together, cucumbers may develop an unpleasant flavor and have reduced yields. It is best to keep these two plants separate.

8. Lettuce and Cabbage

Lettuce and cabbage are both leafy greens that require similar growing conditions. However, when planted together, they can attract the same pests, such as aphids and cabbage worms. To prevent infestations, it is recommended to separate these two vegetables.

9. Peppers and Fennel

Peppers and fennel should not be planted together as fennel can negatively affect the growth and flavor of peppers. Fennel produces chemicals that can inhibit the growth of nearby plants, including peppers.


Knowing which vegetables should not be planted together is essential for a successful and thriving garden. By avoiding these combinations, you can prevent competition for resources, reduce the risk of pests and diseases, and maximize the growth and productivity of your vegetables.
