Melons are good vine plants. They spread out along the ground and cover a great amount of area. This prevents weed growth. In addition, melon is effective in keeping the soil perfectly moist for the proper development of corns.

Cucumber and winter squash gives the same result. These plants help the soil to preserve the necessary moisture.

Why Plant The Companion Plants With Corn? (Top Benefits)

If you are planning on planting different types of corn together, hold your horses. Before getting into the matter, take a quick look at all the benefits of having companion plants with corn below,

1. Puts Off Pests

There are certain plants, such as garlic, that works like natural pest deterrent. Usually, the smell of these plants keeps all the insects and harmful pests away.

2. Attracting Helpful Insects

Some attractive plants, such as borage, invite useful insects. Borage invites pollinating bees. This helps in flourishing the overall growth of corn in your garden.

Some plants invite pest-eating wasps as well. They won’t do any harm to your plant but eat up all the insects slowly devouring your crops.

3. Improve Soil Quality

Usually, the plants suck in nutrients from the soil, leaving the ground dry and unsuitable for other plants. But many plants are known for improving soil quality. For example, the lime tree adds magnesium and calcium to the soil. Both these nutrient elements are essential for the proper growth of corns.

4. Minimizes The Growth Of Weed

Weeds are harmful to your crops. But handling them regularly is also a pain in the neck. You can easily get rid of this situation just by planting more and more companion trees around your corn plants. Extra plants will take up all the nutrients of the soil and leave nothing for the weed.

5. It Saves Tons Of Space

Having multiple plants in a single piece of land saves a ton of space. Instead of allotting different plots for different plants, harvest everything in a single field. This will not only increase your production but leave a lot of areas free for harvesting other crops.

These benefits are undoubtedly good news for you. As you can see, having a companion plant won’t only help your plant grow with efficiency but offer you the opportunity to save cash and space as well.

What Happens if You Choose the Wrong Companion Plant?

Companion trees are indeed your trees’ companions. But to utilize their benefits properly, you have to make sure you are using the right plant in the right way. What if you don’t? Here’s what happens if you wrongly use companion plants for your cornfield,

1. Not Enough Space For The Plants To Breathe

Your corn needs enough space to take nutrients from the soil and consume the sunlight. If any other plants interfere with your crop’s personal space, the crop won’t grow as effectively.

Make sure to maintain enough space between the crops to avoid harmful consequences.

2. Problems With Watering

Some crops require a low amount of water while others demand a lot. A huge problem occurs when both these types of crops are planted side by side. If you water too much, the plant with low water-holding capacity will die. On the other hand, if you water too little, the plant with higher demand for fluid will get weaker soon.

This problem has a simple solution. Just keep the soil moist all the time.

3. Unnecessary shading

Some crops, usually tall ones, provide shades. While shade is beneficial for some plants, the matter is not the same in the case of corn. Corn needs direct sunlight and doesn’t grow well in shady areas.

This is why make sure not to plant tall crops near your corn. It will help your crops grow faster and with abundant nutrients.

As you can see, the downsides of planting companion plants are not that complex. If you know how to handle the situation, you can easily avoid the complications of the wrong companion plants.
