8 Secrets To Grow Sweet Red Peppers – And Get Them To Turn Red Too!
1/Let The Soil Warm
Sweet red peppers, much like their green counterparts, thrive in warm soil that is optimal for growth. If you introduce your pepper transplants to the ground before the soil has had a chance to warm up during the early part of the season, you risk a plethora of issues arising for the plant.
One of the initial issues of planting in cool soil is the potential for the growth of both the roots and the plant to be stunted. This stunted growth can result in weaker plants, as well as decreased flowering and yields in the future. Moreover, planting in soil that is too cool can lead to root rot, which can ultimately result in the death of the plant.
To ensure the success of your sweet red pepper plants, it is crucial to wait for the soil to reach a minimum temperature of 60 degrees before planting. Additionally, using mulch to conserve both moisture and heat in the soil during the early summer can be beneficial. The mulch can also regulate the soil temperature, preventing it from becoming too warm later in the summer and ultimately aiding in the crop’s success.

2/Fill Your Planting Hole With Power

Besides warm soil, sweet red peppers require a fertile and nutrient-rich growing medium to thrive. To achieve this, it’s recommended to amend your planting holes by combining compost and garden soil in a 50/50 ratio during planting. This method not only loosens the soil but also ensures a consistent supply of nutrients for your young plants.
But why stop there? Boost the health and growth of your plants by adding three to four crushed eggshells and a quarter cup of worm castings into the planting hole. The eggshells are an excellent source of calcium, which can help prevent blossom end rot. Additionally, the worm castings serve as a slow-release, easy-to-absorb nutrient source that your pepper roots can readily absorb.
Using both of these additional ingredients enhances the chances of growing a bountiful harvest of juicy sweet red peppers.
3/Allow Space For Your Plants – How To Grow Sweet Red Peppers
Do you want your peppers to ripen faster than ever before? Then, make sure to provide them with ample space! The more sunlight, air, and circulation your pepper plants receive, the faster and more evenly they will ripen.
Sunlight and oxygen are both crucial for powering your plants and ripening their fruit. Additionally, air circulation throughout the plant helps with fruit ripening while also preventing the growth of disease, mold, and mildew.
To promote the growth of large and sweet red pepper plants, it’s recommended to leave at least twenty-four inches between plants. This spacing allows sufficient light and air to reach all parts of the plant. The more crowded the plants are, the longer it will take for the peppers to ripen and turn red.
Moreover, it’s beneficial to prune your pepper plants as they grow. Removing bottom branches helps to increase airflow while eliminating a few middle stems allows more air and light to pass through the plant’s center. By following these tips, you can ensure that your pepper plants will ripen quickly and evenly.
4/Provide Support When You Plant
When planting your pepper crop, it’s crucial to provide support for your plants with stakes or cages. As the peppers mature and grow, they become quite heavy, which puts a lot of stress on the branches. Without proper support, the branches can easily break off, ruining the crop.
Supporting your pepper plants is a must, especially for large and heavy sweet red peppers. Without proper support, the branches can crack or break, resulting in fewer ripe red peppers at harvest time.
It’s best to provide support for your plants at the time of planting. This not only protects them from spring storms but also prevents damage to the roots, which can occur if stakes or cages are driven in later.
Lastly, always remember to mark your red pepper plants to avoid harvesting them too early. It’s easy to forget which peppers are green and which are ripe and ready for picking, so labeling your plants can prevent this common mistake.

5/ Fertilize, But Don’t Over-Fertilize
While red peppers require nutrients to grow and produce, too much of a good thing can actually hinder the ripening process. If a plant receives too many nutrients, it may focus on producing new foliage and blooms instead of ripening the peppers.
To fertilize young sweet red pepper plants, use organic fertilizers or compost tea a few times early in the growing season. However, once the fruit appears, it’s time to reduce the amount of fertilizer.
All-purpose organic fertilizers work well for sweet red pepper plants and other vegetable plants. A good rule of thumb is to apply fertilizer every four weeks, for a total of 2 or 3 applications after planting. After that, it’s best to stop fertilizing and let the pepper plant focus on producing ripe, juicy peppers.
6/Water Well
Insufficient moisture in the soil can cause delays in the ripening process of pepper plants and result in less vigorous fruit. The main reason why many red pepper plants fail to reach their full potential is often due to inadequate watering.
To ensure proper growth and ripening, sweet red pepper plants require approximately 1 to 1-1/2 inches of water or rainfall per week. If there is a prolonged period of dry weather, it is essential to water the plants regularly to maintain their growth and ripening schedule.
7/Be Patient – How To Grow Sweet Red Peppers

Red peppers require more time and patience to turn from green to red than green peppers. Thunderbolt Sweet Red Pepper is a variety that grows to a large size and has a delicious sweet red flavor. Keep in mind that the maturity dates on seed packets refer to producing peppers, not necessarily the time it takes for them to turn red.
After the first green peppers appear on a red pepper plant, it can take an additional three to four weeks for them to fully ripen. This is especially true early in the growing season. However, once the first peppers begin to turn, newer peppers will ripen more quickly.
8/Grow Tried & True Sweet Red Pepper Varieties
In conclusion, it is crucial to choose reliable and high-quality sweet red pepper varieties when planning your garden. While the classic sweet red bell pepper is a common choice, there are other sweet red pepper options that can thrive in a home garden setting. For instance, heirloom varieties such as the Marconi Red Pepper and the Thunderbolt Red Italian Roaster are excellent choices.
These varieties can produce large and flavorful peppers throughout the growing season, even up until the first frost.
