When to Harden Off Pepper Plants?

Determining the right time to start hardening off your pepper plants depends on when the seedlings are scheduled to be moved outside. You also need to consider the outdoor temperature.

The time needed to harden off pepper plants.

Seedlings are ready to be moved outside after 7 to 8 weeks of planting and usually when they reach 6 to 8 inches tall. Regularly placing the plants in a warm place for 2 to 4 weeks before moving them to outdoor garden will give them enough time to get used to the outside conditions. Therefore, hardening off pepper plants can start after 5 to 6 weeks of planting seeds.

How to Harden Off Pepper Plants Seedlings?

The process of how to harden off pepper plants can be affected by many things, such as the temperatures, wind, and the climate in your area. However, these are easy steps to harden off pepper plants that you can follow, considering that your environmental conditions are normal.

#1 Start indoors

Begin the hardening-off process by indirect sunlight exposure to avoid the seedlings being overwhelmed by the high temperature caused by scorching sun.

You can put the plants near a window to get an indirect late afternoon or early morning sun exposure for about 2 hours a day during the first three days. Placing seedlings indoors can also protect young plants from the strong wind and animals that like to eat young foliage.

#2 Increase sun exposure gradually

After three days of indirect sunlight, the plants will get used to the warmth. You can increase the time to 3 or 4 hours of indirect sun daily.

Expose pepper seedlings to sun gradually to harden them off.

You can also start putting plants outside to get 10 to 20 minutes of direct sunlight and increase the time gradually. Do this step for about two weeks. Don’t leave the plant in the sun too long. The young leaves may get sunscald if the sun is too bright!

Apart from training your plant to get used to the sun, you may also need to train your plant to get used to the wind outside. This can be done by exposing your pepper plant to a gentle indoor breeze.

#3 Check the temperature regularly.

If plants grow well after two weeks of regular sun exposure, it’s time to put the plant outside overnight. The temperature outside at night can be unstable, unlike indoors.

To easily monitor the temperature regularly, you can use a mini thermometer with a sensor connected to the plant. That way, you can ensure that the temperature around the plants is above 55°F and below 95°F.

If it’s not possible to get above 55°F at night outside, you are better off placing your young pepper plants indoors.

#4 Move pepper plants outdoors

When the hardening-off process is almost over, and the outside area where the plant will be placed is safe, your pepper plant is now ready to be transplanted into the ground or transferred into a larger container outside.

Remember to put the plant in a well-protected area outside to avoid any unwanted disturbance!

Can I Transplant Mature Pepper Plants?

The purpose of hardening off pepper plants is to adjust the plants to the outside conditions. Transplanting pepper plants when they are young or mature is not a problem as long as they grow well outside.

Even when the plants harden off fast, it’s okay to keep them in a container until they mature and then transplant them. What must be considered is to keep the position of the plants in the same place during the hardening-off process to ensure the plant is accustomed to the climate outside.

Replanting pepper plants.

Hardening off pepper plants will prevent the plants from having shock when moving to a new place or dying from sudden changes in conditions. It’s always better to prevent than to deal with any bad situation that may happen to your pepper plants.
