why won't my peppers turn red

There might be four reasons this might be happening. The first reason might be that your plant is not fully ripe yet. Or maybe your pepper might not be of the red variety. The temperature might even be too high or low. Moreover, there might also be a pest problem. 

Well, these were just the reasons why it didn’t turn red. Want to know what to do to make that happen? Good! Cause we have got a detailed segment on this below, so dive in!

Reasons Your Pepper Isn’t Turning Red

There might be a few different things that might tick off the maturing process. If this is your first time planting, it’s alright. We got you! Follow ahead to know all the details. 

Reason 1: It Might Not Be Fully Ripe Yet 

If this is your first time planting bell peppers, this is a common mistake. You might’ve followed the instructions and planted your plant.

The time period on your packaging might be around 6 weeks. But that’s not actually correct. What I mean is that after the six-week period, your pepper will become mature. But just enough so that you can eat it. 

How Long Will It Take To Turn Red?

Well, bell peppers take a long time to grow and fully ripen. After that, the green pepper will take another 2-3 weeks to change color. It will turn yellow from green and then red. 

Therefore, you need to have patience. If your pepper is large, it’ll take longer than 3 weeks to ripen. Thus, wait for another one week or so to see results. 

But if you want them to change color quickly, opt for a smaller size next time. Usually, those between 2-5 inches in diameter and 2-6 inches in length are the best!

Reason 2: Your Pepper Might Be Of Green Variety

This might be another reason your pepper is not turning green. Even after you’ve waited for more than two weeks after the given period. 

Your pepper might be one of the kinds that might never turn green. But there isn’t a problem with your plant. It is just one of its varieties and it stays green after it has ripened. There are some that turn into colors such as yellow, orange, dark brown, etc. 

What To Do With Different Variety of Peppers?

Well, you can enjoy using the green bell peppers for now. When you’re replanting, opt for ones that are sure to turn red. Make sure to ask your seller to give you the red variety. Or check the packaging for this.

You can buy seeds of bell boy, lipstick, gypsy, or the lady bell. These varieties will definitely turn red once they are ripe. 

Here are some great varieties of red pepper you can choose from:

Using these seeds, your garden is going to be full of red peppers. And that’s definite!

Reason 3: The Temperature Might Not Be Right

These plants are quite picky about the condition they grow in. Therefore, your temperature needs to be warm for the plant to mature perfectly. 

The humidity also helps the plant to change color quicker. If the temperature is too cold, the plant might face difficulty in changing color.

What Temperature is Optimum for This Plant?

These plants grow the best when the temperature is high. A set temperature of 70-80 degrees Fahrenheit during the day is optimum. 

A temperature that falls below 55 degrees Fahrenheit might be damaging to the plant. The plant might even drop flowers, forming yellow leaves. It might not get a chance to develop.

Moreover, if the temperature is higher than 90 degrees the plants will be affected. 

Therefore, you need to plant your pepper 12-16 weeks before the expected frost. If you’re growing the plants indoors, maintain a constant temperature with your heating system. 

In this way, the temperature will be perfect. It’ll slowly ripen into beautiful red peppers! 

Reason 4: You Might Have A Pest Infestation 

The pepper matures from green to yellow and then red. But if your pepper looks yellowed at parts and discolored, there might be an aphid problem.

These are pests that suck juices from leaves. This is why your plant looks discolored. Moreover, these aphids might even kill your plant. 

How to Get Rid Of Pests?

You can use insecticidal oil or soap to prevent these aphids. Just rub either on both sides of the leaves and hose it down. 

Moreover, welcome some bugs that feed on aphids to your garden. These bugs might be lady beetles, parasite wasps, soldier beetles, lacewing larvae. 

These are basically the reasons why your plant might not be turning red. Therefore, take good care of your plant by implementing these guides.
