The Ultimate Guide to Growing Bell Peppers from Seed.

Fruit Gardening
Written By Jennifer Bruce

Bell pepper plants are a type of flowering plant that belongs to the nightshade family. They are native to Central and South America, but they are now grown in many parts of the world. Bell peppers are a popular vegetable that can be eaten raw or cooked, and they come in a variety of colors including green, red, yellow, and orange. This vegetable care guide will walk you through all the tips and tricks for growing bell pepper plants from seed to harvest.

Bell pepper plants require plenty of sunlight to grow and produce fruit. They should be planted in an area that receives at least 6-8 hours of direct sunlight per day. In areas with hot summer temperatures, it is a good idea to provide some shade for the plants during the hottest part of the day to prevent the fruit from sun scald.

  • These are the most common type of bell peppers and have a mild, slightly sweet flavor.

  • These are ripe green bell peppers that have been allowed to fully mature on the plant. They have a sweet and slightly fruity flavor.

  • These are similar to green bell peppers in flavor, but they have a slightly sweeter taste.

  • These have a sweet, tropical flavor and are often used in salads and other raw dishes.

Bell pepper plants do not require high humidity levels to grow and produce fruit. In fact, they can be sensitive to high humidity levels, which can lead to fungal diseases such as powdery mildew. It is generally recommended to keep the humidity level around the plants at 50-60% to promote healthy growth. In areas with naturally high humidity levels, it may be necessary to provide additional ventilation to help reduce the risk of fungal diseases.

Bell pepper plants prefer warm temperatures and will not tolerate frost. They should be planted outdoors after all danger of frost has passed and the soil has warmed to at least 60°F (15°C). During the growing season, bell pepper plants prefer daytime temperatures in the 70-80°F (21-27°C) range and nighttime temperatures that do not drop below 60°F (15°C). Higher temperatures can cause the plants to become stressed and may result in reduced fruit production.

Bell pepper plants have moderate watering requirements and should be kept consistently moist, but not waterlogged. Water the plants deeply about once a week, or more frequently in hot or dry weather. Be sure to check the soil moisture level before watering by sticking your finger about an inch into the soil. If the soil feels dry at this depth, it is time to water. Avoid overwatering, which can lead to root rot and other problems.

Mix of compost, sand, 6.0-7.0 pH. Bell pepper plants grow best in well-draining soil with a neutral to slightly acidic pH level of 6.0-6.8. A good soil mixture for bell peppers consists of a combination of compost or well-rotted manure, peat moss, and a balanced fertilize, such as a 10-10-10 formula. In addition to providing the plants with the nutrients they need, a well-draining soil mixture will help prevent the roots from becoming waterlogged, which can lead to problems such as root rot.

Starting bell peppers from seed, can be a daunting task for beginners. Here are 7 easy steps to successfully grow bell peppers from seed. 

  1. Start the seeds indoors about 6-8 weeks before the last frost date in your area. Fill a seed tray or pots with a well-draining seed starting mix and moisten the soil.

  2. Sow the seeds about 1/4 inch deep in the soil and cover them with a thin layer of soil or seed starting mix.

  3. Place the tray or pots in a warm location (at least 70°F/21°C) and keep the soil moist.

  4. Once the seedlings have emerged and have their first true leaves, thin them out to leave only the strongest seedling in each pot or cell.

  5. When all danger of frost has passed and the soil has warmed to at least 60°F (15°C), transplant the seedlings into the garden or into larger pots.

  6. Plant the seedlings in an area that receives at least 6-8 hours of direct sunlight per day and has well-draining soil. Space the plants 18-24 inches apart in rows that are 2-3 feet apart.

  7. Water the plants deeply about once a week, or more frequently in hot or dry weather. Mulch the plants to help retain moisture in the soil. Fertilize the plants every 2-4 weeks with a balanced fertilizer, such as a 10-10-10 formula.

Note: If you are planting the seeds directly in the garden, follow steps 4-7 above, sowing the seeds 1/4 inch deep in the soil and thinning the seedlings as needed.

Companion Planting

Bell pepper plants can benefit from being grown alongside certain companion plants. Some good companion plants for bell peppers include basil, parsley, marigold, and nasturtium. These plants can help deter pests and improve the health and flavor of the bell peppers. It is generally best to avoid planting bell peppers alongside plants that are prone to attracting the same pests or diseases, such as tomatoes or eggplants.

To harvest bell pepper plants, follow these steps:

  • Look for peppers that are fully ripe and have reached their desired size and color. Bell peppers can be harvested when they are green or when they are ripe and fully colored.

  • Gently twist or cut the pepper from the plant using a pair of scissors or a sharp knife. Avoid pulling on the pepper, as this can damage the plant.

  • If the plant is producing more peppers than you can use at once, you can leave some on the plant to continue ripening. Be sure to check the peppers regularly and harvest them as soon as they are fully ripe to prevent them from overripening and rotting on the plant.

  • After harvesting the peppers, wash them thoroughly and store them in the refrigerator until you are ready to use them. Bell peppers can be stored in the refrigerator for up to a week or so, depending on their freshness when they were harvested.

  • If you would like to preserve the peppers for later use, you can freeze or preserve them by pickling, canning, or drying.

To prevent pests and diseases from affecting your bell pepper plants, be sure to follow proper gardening techniques such as rotating your crops, providing adequate spacing between plants, and avoiding overcrowding. You can also use natural pest control methods such as releasing beneficial insects or using organic pest repellents. If you do notice pests or diseases on your plants, it is important to take action promptly to prevent the problem from spreading. This may involve removing infected plants, applying a pest control product, or using other control methods as appropriate.

Once the plants have finished producing fruit and their growing season is over, they will die off and need to be replaced with new plants the following year.
