Plants You Should Never Grow Next To Each Other

Just like humans, some plants are also just incompatible together. After all, all the plants within a garden are like a community. Some need their space, some don’t mind being clumped up with their neighbors. By creating a peaceful community, you will ensure that everyone is happy, and they’ll grow big, storing and give a bountiful harvest. Also keep an eye out for any unwanted guests, such as pests, that may bring havoc into your picturesque garden community. So, let’s take a look at which plants don’t get along and that you should never grow next to each other.

Make sure you water the garden regularly

Corn and Tomatoes

While these two make a great match in certain dishes, when it comes to growing next to one another, they make a terrible combo. Unlike other incompatible plants, corn, and tomatoes don’t do any harm to another directly. Rather the problem here is that they both are prone to pests such as fungal blights and worms. If one of them gets these pests, the other will as well. Making an infestation in minutes. Plant tomatoes next to basil, while corn goes well with pumpkins and beans.

Zucchini and Potatoes

Both potatoes and zucchinis are loved for their fast-growing rate. However, when planted together, this is what causes their downfall. Potatoes especially are very aggressive feeders. They have no shame in stealing precious nutrients from the soil without sharing any. This leaves the poor zucchini to struggle to get barely anything to eat. So, while you’ll have plenty of potatoes, you won’t be enjoying any zucchini if you plant these two together. Grow your zucchinis next to corn or melons. While potatoes should go next to basil or horseradish.

Garlic and Peas

These two do more harm to one another than good. While garlic does great with many plants as pest control, with peas that isn’t the case. The strong sulfur compounds found in garlic will stop the delicate peas from growing into their full form. So, make sure these to stay away from each other. Rather, try to plant your peas next to cucumbers or beans. Whereas the garlic goes great with eggplants and tomatoes.

Summer Squash and Pumpkins

Pumpkins are aggressive growers. Both plants have long vines and will battle each other for any available space. Pumpkins especially can easily choke out any summer squash to take it’s space and water. Not only that, but pumpkins can cross-pollinate with other types of squash, and it will affect your harvest. So, make sure to plant these plants away from one another. Try growing your pumpkins next to corn or melons, whereas your summer squash next to herbs or beans.

Rosemary and Cucumbers

Cucumbers are somewhat of a blank canvas. By this we mean that they are made primarily up of water, which doesn’t really have a strong taste. So, planting them next to strong, aromatic herbs such rosemary, sage, and basil will make them take on the taste. While this isn’t the worst thing in the world, we prefer our cucumbers with a neutral flavor.
