List of Incompatible Plants and Reasons Why 

List of Incompatible Plants and Reasons Why


Gardeners do all they can to keep their plants happy and healthy, but sometimes, no matter what you do, certain plants just don’t go together. Plants that don’t like each other may be responding to different environmental needs, could be in direct competition with one another for major resources or one may attract insects that severely harm the other. Determining plant incompatibility can be a guess and check situation since soil types also have an influence on what plants should not be planted together.


There are a few basic rules of thumb when it comes to plants to avoid near one another. First, check that your garden plants are all about the same size and have the same light requirements. Planting very tall plants like tomato next to bush beans, for example, is a very bad idea since the tomatoes will very likely shade out the beans.


Plants that need a lot of water will cause those water haters nearby a great deal of discomfort; the same goes for fertilizer. It is always a good idea to plant things with similar nutritional and water needs together, unless they’re fiercely competitive. Even then, you can often compensate by spacing them extra wide and providing enough fertilizer and water for both types of plants.


Popular vegetables and what they can’t grow with

Asparagus – Asparagus does not like garlic and fennel in the neighborhood. Fennel is a bad companion to a lot of veggies, but the problem between garlic and asparagus could stem from competition for the same nutrients by these sulfur-rich veggies or some other reason.


Beans – Being a legume, bean plants have the capacity to enrich the soil by nitrogen fixing, so they are often planted in between other veggies, especially spinach, cucumber, corn, and potato. However, beans shouldn’t be planted near veggies of the cabbage and onion families. These include cauliflower, broccoli, kale, cress, mustard, garlic, chives and leeks. 


Broccoli – Surprisingly, this green delight does not like basil. Also, avoid planting beans, peas, tomatoes, and strawberry plants near broccoli.


Carrots – Carrots thrive beside legumes like beans and peas and nightshade family vegetables. But celery and dill are two herbs carrots are not happy about.

Cauliflower, Cabbage, Kale – All three of them have animosity towards basil. Tomatoes are incompatible with them, so are beans. Also, avoid planting either of them in your strawberry patch, and vice versa.


Corn – Both corn and tomatoes are heavy feeders, which could be a reason for incompatibility. If the soil is rich enough, they may not suffer as many ill effects when planted close to each other.


Cucumbers – Cucumbers are a highly rewarding vegetable suitable for even novice gardeners. Potato is the exception here. Cucumbers seem to hate the company of aromatic herbs such as basil, sage, marjoram and rosemary for some reason.


Lettuce – These delicate leafy greens may seem like a cabbage relative but they actually belong to the daisy family. Lettuces are known for being intolerant of Allium family members, including onions and garlic.
