Growing Peppers

 

  • Ideal Soil pH: 6.0 - 6.8

  • Ideal Climate: 60 - 85 degrees Fahrenheit

  • Daily sunlight for mature plants: 6 - 8 hours direct sunlight

  • Watering mature plants: Let top 1/2 inch of soil dry out between watering

Step 1: Choosing a Location to Plant Peppers

​

Peppers are warm-season plants and require a frost-free growing season with consistently warm temperatures. Choose a location that is sheltered from cold winds and has good air circulation to prevent diseases. Pepper plants can vary in size depending on the variety, so make sure you have enough space to accommodate them. Plant peppers at least 18 to 24 inches apart to allow for adequate air circulation and room for growth. Select a spot that receives at least 6 to 8 hours of direct sunlight per day. Peppers thrive in full sun, so choose a location with ample sunlight exposure throughout the growing season.

​

Step 2: Choosing Pepper Seeds

​

Peppers come in a variety of shapes, sizes, colors, and flavors. Determine whether you want sweet peppers, hot peppers, or a combination of both. Some popular sweet pepper varieties include bell peppers, banana peppers, and pimento peppers, while common hot pepper varieties include jalapeños, habaneros, and cayenne peppers. When growing peppers, consider the heat level that suits your taste preferences. Pepper varieties vary widely in their heat levels, ranging from mild to extremely hot. Check the Scoville Heat Units (SHU) rating for each variety to gauge its heat level. Also pay attention to the days to maturity listed for each variety. Some peppers mature quickly, while others take longer to reach harvestable size. Choose varieties that fit within your growing season and climate.

Where to Get Seeds

Lettuce seeds are easy to find at almost any home improvement or garden store. As always, there are almost an unlimited amount of varieties online and it is always best to opt for organic if you can.

Step 3: Preparing Soil for Growing Peppers

​

Use a garden fork or tiller to loosen the soil to a depth of about 8 to 12 inches. This improves soil aeration, drainage, and root penetration. Add organic matter such as compost, well-rotted manure, or aged leaf mold to improve soil structure, fertility, and moisture retention. Aim to incorporate a 2- to 4-inch layer of organic matter into the soil. Apply a layer of organic mulch, such as straw, shredded leaves, or wood chips, around the base of the plants. Mulch helps suppress weeds, retain soil moisture, and regulate soil temperature.

​

Step 4: Planting Pepper Seeds

​

Start pepper seeds indoors 6 to 8 weeks before the last expected frost date in your area. Peppers require a long growing season, so starting seeds indoors gives them a head start and allows them to mature before transplanting them outdoors. Use clean seed trays, cell packs, or small pots with drainage holes to plant the seeds. Make sure the containers are at least 2 to 3 inches deep to accommodate the seedlings' roots. Fill the containers with a sterile seed starting mix or a mixture of peat moss, perlite, and vermiculite. Avoid using garden soil, as it may contain pathogens that can harm young seedlings. Plant 2 to 3 pepper seeds per container, spacing them evenly and planting them at a depth of about ¼ to ½ inch. Gently press the seeds into the soil and cover them lightly with additional seed starting mix. Water the containers thoroughly after planting to ensure the soil is evenly moist. Use a spray bottle or a gentle stream of water to avoid disturbing the seeds. Place the containers in a warm location with temperatures between 70°F to 80°F (21°C to 27°C). You can use a seedling heat mat to provide bottom heat, which can help speed up germination. Cover the containers with plastic wrap or a humidity dome to retain moisture until the seeds germinate. Once the seeds germinate and seedlings emerge, remove the plastic wrap or humidity dome and place the containers in a location with bright, indirect light. Supplemental grow lights can be used if natural light is insufficient. If more than one seedling germinates per container, thin them out by removing the weakest seedlings, leaving only the strongest one to grow. When the pepper seedlings have developed 2 to 4 sets of true leaves and the weather has warmed up, they are ready to be transplanted outdoors. Harden off the seedlings by gradually exposing them to outdoor conditions before transplanting them into the garden. Start off hardening by exposing seedlings to 1 hour on morning sunlight, add an hour of sunlight exposure everyday for a week.

​

Step 5: Watering Pepper Plants

​

Water pepper plants deeply but infrequently. Aim to water the plants when the top inch of soil feels dry to the touch. Avoid overwatering, as peppers are susceptible to root rot if the soil remains consistently soggy.

​

Its best to water in the morning hours when the moisture is able to penetrate the soil before it evaporates. It is also good practice to focus the watering around the base of the plant and avoid watering the foliage to reduce the chance of diseases developing.

Step 6: Fertilizing Pepper Plants

​

Select a fertilizer that is specifically formulated for vegetables or tomatoes, as these formulations typically contain the right balance of nutrients for pepper plants. Look for a fertilizer with a balanced N-P-K (nitrogen-phosphorus-potassium) ratio, such as 10-10-10 or 5-10-10. Before transplanting pepper seedlings into the garden, mix a slow-release fertilizer into the soil according to the package instructions. This will provide a steady supply of nutrients as the plants grow. While nitrogen is essential for healthy foliage growth, too much nitrogen can result in lush foliage at the expense of fruit production. Avoid high-nitrogen fertilizers, especially later in the growing season when peppers are setting fruit.

​

Step 7: Harvesting Peppers

​

Peppers can be harvested at various stages of maturity, depending on your preference and the variety you're growing. Most peppers can be harvested when they are green and immature, but they will continue to ripen and change color as they mature. Monitor the color of the peppers. They will change from green to their mature color as they ripen. For example, bell peppers typically turn yellow, orange, red, or purple when fully ripe, while hot peppers may turn red, orange, yellow, or even chocolate brown, depending on the variety. Gently squeeze the peppers to assess their texture. Ripe peppers should feel firm and have a glossy appearance. Avoid peppers that feel soft or have wrinkles, as they may be overripe or starting to spoil. When harvesting peppers, use sharp pruning shears or scissors to cut the peppers from the plant. Make a clean cut about 1 inch above the top of the pepper to avoid damaging the plant.

 

Time to Harvest:

​In general peppers take 60 to 90 days from transplanting to reach maturity and be ready for harvest.
