Question 1

How many hours of sunlight does Corn plant need per day?

Accepted Answer

Corn plant needs a lot of indirect, filtered, or dappled light when grown indoors, so they should be kept in a sunny location all day. Of course, the number of daylight hours that occur naturally can vary depending on the season, but a good rule of thumb is a minimum of 6 hours, including up to 3-6 hours of direct sunlight per day. Even many hours of indirect sun will not hurt Corn plant; it is only direct sun that you need to be careful about.

Question 2

What type of sunlight does Corn plant need?

Accepted Answer

Corn plant in the wild get a lot of sunlight throughout the whole day. The sunlight is dappled and mostly indirect since it is filtered through the leafy canopy of tall trees growing above. When grown indoors, Corn plant should be provided with bright indirect light in a sunny windowsill or via grow lights.

Question 3

Does Corn plant need to avoid sun exposure?

Accepted Answer

Corn plant does not need to avoid sun exposure completely, but the type of sunlight should be appropriate. They should not be exposed to more than 6 hours of direct sun each day. Direct sun means that the sunlight is hitting the plant directly. Indirect light could be reflected off other objects near the plant, or could be direct sun that is filtered by something such as a sheer curtain. So Corn plant should be protected from excessive direct sun.

Question 4

What happens to Corn plant if it gets too much sunlight?

Accepted Answer

Too much direct sunlight will scorch the plant’s leaves, especially the upper leaves which are hit with the majority of the sun’s rays. Scorched spots on the leaves look brown and dry. Entire leaves may also wilt and turn brown. Being grown in full sun can cause the soil to dry out too quickly. In extreme cases, too much sun could kill the plant.

Question 5

What happens to Corn plant if it receives insufficient sunlight?

Accepted Answer

Without enough sunlight, Corn plant become etiolated (tall and stretched out) and lose color in their leaves. Over time, the plant is not able to generate enough energy through photosynthesis to support its continued survival, and will die if it is kept in a dark location.

Question 6

Does Corn plant need special attention to sunlight during different growth stages?

Accepted Answer

Corn plant should get bright indirect light regardless of their growth stage. If anything, consistency in lighting conditions will get you the best results. Once you’ve found a location where your plants are happy, it is best not to move them. However, you should monitor the location and move plants if sunlight gets too intense during summer or becomes too dark in winter.

The amount of light can affect other elements of plant care as well, particularly temperature and watering frequency. More sunlight and heat will cause water to evaporate from the soil faster, meaning you would need to water more often. Less sunlight also usually means less watering, and usually cooler temperatures. This can lead to disease or pests.

Finally, be careful when moving Corn plant from a shady location to a sunny one, such as moving plants to spend the summer outside. Corn plant can easily get sunburned if they are moved suddenly from a location with little-to-no direct sun to a spot that gets a lot of bright light. Make this kind of move gradually, starting with just 1 to 2 hours in the new location per day and gradually increasing the time. This method allows the plant to adjust to the increased light levels without getting scorched.

Question 7

How much light does Corn plant need for photosynthesis?

Accepted Answer

Even the smallest amount of sunlight triggers the process of photosynthesis in plants. However, the amount of energy produced through that process needs to be enough to support the plant’s current survival and continued growth. Without plenty of sunlight, the plant will essentially starve because it doesn’t have what it needs to create energy.
