Corn Plant Care & Growing Guide

1. Light Requirement

You need to keep this plant away from direct sunlight, as it can do a lot of damage within a fairly short amount of time. If you keep your plant inside in front of a western-facing window, it should have curtains or blinds to filter the light.

The fact is that these plants don’t do very well when they are bombarded with bright sunlight throughout the day. While these plants can survive in low light environments, their coloration usually becomes duller.

It is best to provide your corn plant with a moderate amount of light each day. If you are going to keep it outside, make sure that it is in a nice shady area.

2. Water

When it comes to watering your corn plant, it is important that you thoroughly soak the soil. You don’t want to water it again until the soil has become fairly dry, but not bone dry. This can be a little tricky at first, but it won’t take long for you to get the hang of it.

Watering these plants too much or too often can quickly lead to root rot, which can cause irreversible damage. If the soil still feeling fairly moist, you’ll want to wait a bit longer before watering it again. This is a crucial part of maintaining these plants, so you’ll need to keep it in mind.

3. Climate

These plants can be grown in plant hardiness zones 10 through 11. They thrive in moderate climates that are not too hot or cold.

5. Temperature

Corn plants tend to do best in a temperature range of 60 to 75 degrees Fahrenheit. You definitely don’t want to expose this plant to temperatures below 55 degrees Fahrenheit, as the cold can cause serious damage.

Temperatures higher than 75 degrees Fahrenheit can burn the leaves, which also isn’t good. If the weather starts getting very hot, you can turn the leaves so they are facing away from the sun. This should help with minimizing damage to the leaves.

6. Repotting

When you are ready to repot this plant, you’ll first need to take out all of the soil and gently remove the plant from its container into a bigger one. You need to be careful not to harm the roots at all while you are doing this.

The next step in this process is to fill up the container around the plant with the appropriate soil. You don’t want to pack it in too tightly, as it needs to be able to drain the water efficiently. Tightly packed soil can encourage root rot with your plant, which is the last thing you want.

7. Speed of Growth

Corn plant grows at a moderately fast speed, but much less so when it is kept in a low light environment. You can significantly speed up the growth of this plant by simply providing it with a healthy amount of natural sunlight throughout each day.

8. Height and Spread

These plants can grow up to 180 inches tall with a maximum spread of 48 inches. You will therefore have to carefully choose a spot where it will have room to grow out.

9. Flowers

The flowers that this corn plant produces are very potent with a sweet fragrance that you’ll likely find very pleasing. They are usually pure white and form in clusters. It is pretty uncommon for this plant to produce flowers though.

10. Trimming

If you notice any damage to your corn plant’s leaves due to excess cold or sun exposure, you should trim them. It is, however, important for you to let the plant full recover before going ahead and doing this.
