How to Grow Peppers
When to Plant Peppers
The ideal time to plant peppers is after the last frost date and when the soil has warmed up to around 70°F (21°C) or higher. In most regions, this is typically during late spring to early summer.
Starting pepper seeds indoors about 8-10 weeks before the expected transplant date can give your plants a head start. However, be careful not to move them outdoors too early, as peppers are sensitive to cold temperatures. Wait until the weather has stabilized, and both daytime and nighttime temperatures are consistently warm before transferring your pepper seedlings to the garden.
By timing your planting carefully, you’ll set the stage for a successful pepper growing season and enjoy a bountiful harvest.
How to Plant Peppers
Start by selecting a sunny location in your garden with well-draining soil. Enhance the soil by mixing in organic compost to boost fertility and improve drainage. Once your pepper seedlings have developed their first true leaves, transplant them into the garden. Space them 18-24 inches apart in rows that are 30-36 inches apart. In raised beds, you can space them a bit closer if needed.
Ensure the young pepper plants receive adequate water and are protected from any lingering cold snaps. Use mulch to help retain soil moisture and suppress weeds. If you’re in a region with a short growing season, consider using black plastic mulch to raise soil temperatures and promote faster growth.

Pepper Care and Maintenance
Proper care and maintenance are important for robust pepper growth and a plentiful harvest. Ensure consistent watering throughout the growing season to keep the soil evenly moist. Avoid overwatering, as peppers are prone to root rot.
Apply a layer of organic mulch around the plants to retain soil moisture, regulate temperature, and suppress weeds. Provide support if needed to keep the pepper plants upright and prevent them from toppling over under the weight of the fruit.
Monitor for common pests such as aphids, spider mites, and beetles. Use natural remedies like neem oil or introduce beneficial insects to manage infestations effectively.
Feed your peppers with a balanced fertilizer or add compost to the soil every few weeks to provide essential nutrients. Pruning lower leaves and suckers can enhance air circulation and light penetration, promoting better fruit development.
Harvesting and Storing Peppers
Harvesting peppers at their peak flavor and quality is the rewarding result of your gardening efforts.
To harvest peppers, wait until they have reached their mature size and color, which typically occurs 2-3 months after transplanting. Gently cut the peppers from the plant using pruning shears or a sharp knife, leaving a short stem attached. The peppers should be firm and vibrant in color.
Avoid letting peppers become overly mature, as they can develop a bitter taste and tougher skin. For the best taste and texture, use peppers promptly after harvesting. If you cannot use them immediately, store them in a cool, dry place or in the crisper drawer of the refrigerator for up to one to two weeks. Peppers are sensitive to cold temperatures, so avoid storing them near items like tomatoes, which emit ethylene gas and can cause premature spoilage.
