#Cabbage

Cabbages are from the brassica family, which includes broccoli, brussels sprouts, kale, and cauliflower. Plants from this family should be kept far away from tomatoes. Tomatoes and brassicas are sworn enemies. This is because they will inhibit your tomato’s growth and since they tend to be heavy feeders, they will steal all the nutrients they need. Tomatoes simply lose the competition to cabbages and the others from their family. So, make sure to keep them far apart.

#Corn

Corn is a problematic neighbor for tomatoes. This is because this yummy plant tends to attract one of the most destructive pests around – the corn earworm. It is a type of moth and its larvae like to feed on every part of the corn. However, this pest doesn’t only like corn, it also enjoys feasting on tomatoes. They burrow into the fruit and once they are in, they are very difficult to get out. So, to save yourself from the troubles of corn earworm keep these plants far away from one another.

#Dill

Tomatoes and dill have a love-hate relationship. On one hand, dill helps keep pests like aphids away, while tomatoes help stop strong winds from managing young dill plants. However, once that dill plant has grown big and strong it will backstab the tomato plant and start stealing nutrients thus stunning your tomato plant’s growth. Due to this reason, it is not recommended to keep these plants near one another. You can plant tomatoes near young dill, but only for one season, other than that steer clear from mature plants.

#Fennel

Fennel is a wonderful addition to a variety of dishes, that’s why it is great to have in the garden. However, this crop does not play well with others and this is especially true for tomatoes. This is because fennel roots leak out a special kind of secretion that stops any plants around them from growing. In general, it’s best to keep fennel away from all other crops.

#Potatoes

Potatoes are a wonderful root vegetable. However, just like tomatoes, they are a part of the nightshade family, which means they both need the same kind of nutrients to grow. So, when they are planted next to each other, they will viciously compete for nutrients and stunt each other’s growth. Not only that, but these plants are also susceptible to the same types of diseases, which mean that if one of them caught a disease, it will spread through the soil and take down both plants. That’s why tomatoes and potatoes should not be kept in close proximity.

#Eggplant

The situation with eggplants is much like the one with potatoes. Eggplants are also a part of the nightshade family, so they are natural competitors with tomatoes. Plus, eggplants are susceptible to a fungal disease called blight that is a fast spreader and very hard to eradicate. It spreads through the garden through spores blown by the wind. And if you have planted other plants from the nightshade family near eggplants, which are also susceptible to such diseases, they will be taken down from the blight.

#Strawberries

Tomatoes and strawberries may grow in the same season, but they shouldn’t be grown next to each other. It’s best to keep these two plants far away from one another. This is because both plants are prone to carrying a dangerous fungal disease that can be fatal. And since they are both prone to it, if one plant catches it, it takes the other plant down with it as well. That’s why it is best to avoid planting these two close together.
