Worst Companion Plants

If you follow companion planting rules, you will know that some plants cannot grow together. One of the primary reasons behind this is that the growth of one plant can inhibit the development of the other. In this discussion, some of the most common plants that you should never be growing with your eggplants are:

1. Pumpkins

The first plant that you should not be growing close to your eggplant is none other than pumpkins. It is because many germs are attracted to pumpkins. You will notice that the pumpkins grow on plant structures, which is usually to ensure that germs do not destroy them.

If you plant the eggplant and the pumpkin together, there is a high chance that the insects will end up damaging the quality of the eggplant. As we have already mentioned, the latter is a very soft vegetable, and thus it would take little time for the insects to destroy it. Try to keep at least a few inches of a gap to promote the healthy growth of both plants.

2. Melons

The following variant of plant that you should most certainly not be growing next to your eggplants is none other than the melons. You must have noticed that both melons and pumpkins are enormous. Hence if you plant both of these together, one may crowd out the next. What happens next is that there needs to be more space for optimum growth, and they turn out to grow small.

Also, if you are growing melons and pumpkins on the same plant support, you will see a high chance of it snapping. It is because the weight of melons and pumpkins can be pretty heavy, making it impossible to carry them the same.

3. Corn

If we go by the rules of companion planting, the following variant of plant that you should not be placed next to your eggplant is none other than corn. It would be wrong to say that corn is exceptionally harmful to eggplants; however, corn plants have a particular characteristic that is difficult on the eggplant. The nature of corn is such that they take all the significant resources from the soil.

Consequently, you will notice that the eggplant will not be able to absorb any of the nutrients, and slowly it will start dying out. Even if the eggplant doesn’t die out, there is a high possibility that it will not be healthy, and this is because of the absence of nutrients. Try to make sure that you plant these quite a few feet away.

4. Fennel

Some plants do not go well with other companions, and fennel is one of them. One of the significant disturbances a fennel plant will cause is that it will take up all the essential nutrients and leave your eggplant malnourished. Not only that, you will notice that such is the nature of a fennel plant that will attract a particular variant known as geraniums.

This geranium damages the plant, sometimes even eating up the entire plant. Eggplants are very susceptible to such damage, primarily because of the nature of the plant. Always make sure that you keep fennel away from your eggplant if you want a healthy plant.

5. Kohlrabi

You will notice that many other plants tend to benefit from its growth, such as the nature of the Kohlrabi plant. However, we can vouch that eggplant differs from one of them. One of the primary reasons behind this is that Kohlrabi attracts a particular insect known for infesting fruits and vegetables.

You are good to go if you can take care of the infection. But in most cases, it becomes difficult to notice, and hence it ends up causing much damage. It would be a safer decision not to plant Kohlrabi and eggplant together.


Can you plant eggplant close together?

It is always better to plant the eggplants at least at a distance of 6 inches apart. One of the primary reasons behind this is that you will break the branches while harvesting the eggplants if they are more extensive. Even if the eggplants are small and compact, giving this much distance in between is very important.

How long do eggplant plants live?

If you can maintain your eggplants with optimum watering and the right kind of fertilization, then there are no doubts that they can last very long. In warm climates, you will notice that eggplants can live up to 4 to 5 years by producing healthy vegetables each season.

How deep do eggplants go?

As per the standard variant, eggplants tend to go deep for a distance of about 2 feet. Try to make sure that you can water it in a way so that the roots are not deprived.

Do eggplants need deep pots?

We suggest planting the eggplant directly into the soil if you can afford to do so and have the space. On the contrary, if you do not have such a white space, you can go for a pot with a depth of about 12 to 14 inches. It will help the eggplants to thrive over the years. If you notice the plant growing more than anticipated, you can replant it in a 20-inch pot. There are high chances of better growth of eggplants.

Can eggplant survive 40 degrees?

The ideal temperature to grow eggplant is not more than 30° C. If the temperature rises to 40 degrees, there are chances that it can cause a delay in the production of the fruits.


Companion plants are beneficial for your eggplant to grow. It promotes healthy growth and keeps insects away. Mostly, people prefer to plant herbs as companion plants because of their insect repelling properties. But it is best to choose companion plants that can mutually benefit each other and grow without any discomfort.
