Planting
Grow peppers in a space with full sun and well-draining, moist (but not wet) soil. Plant peppers in a spot where they will get at least 6 hours of direct sunshine every day. A balance between sandy and loamy soil will ensure the soil drains well and warms quickly. Mix large amounts of organic matter (such as compost) into the soil, especially when working with heavy clay.
Avoid planting peppers in places where you’ve recently grown other nightshade family members—such as tomatoes, potatoes, or eggplants—as this can expose peppers to disease.
When to Plant Peppers
- To start peppers indoors in pots, sow seeds 8 to 10 weeks before your last spring frost date.
- Plant pepper starts or transplants outdoors about 2 to 3 weeks after the threat of frost has passed and the soil has reached 65°F (18°C).
How to Start Peppers Indoors
- To start indoors: Start pepper seeds 1/4-inch deep, three to a pot filled with potting mix. For faster germination, maintain soil at 70°F (21°C) or above. To achieve these sorts of temperatures, you’ll probably need a heated propagator or heat mat and some grow lights.
- Ideal conditions should see seedlings appear within about 2 weeks, but some varieties take as long as 5 weeks, so don’t give up on them too soon! Thin out the weakest seedling; let the remaining two pepper plants in each pot grow as one. The leaves of two plants help to protect the peppers.
- If seedlings become leggy or too tall before it’s time to plant outside, replant them in a bigger pot up to their lowest leaves, just like tomatoes, to help support them. Keep seedlings warm with plenty of light until you’re ready to plant. If the plants have around five to eight leaves and you can see roots at the drainage holes, it’s time to move them up a pot size.
- Be sure to harden off the seedlings about 10 days before transplanting outdoors, as peppers are very sensitive to cool temperatures. Before planting peppers outdoors, acclimatize plants to outdoor conditions by placing them in a sheltered spot outside for gradually increasing periods over 2 weeks. Take care to avoid frosts. Plant out only after your last expected frost date has passed.
How to Plant Peppers Outdoors
- If you’re buying pepper starts, choose ones with straight, sturdy stems, 4 to 6 leaves, and no blooms or fruit. To harden off pepper plants, set plants outdoors a week or more after the frost-free date or when the average daily temperature reaches 65°F (18°C).
- Before transplanting in the garden, mix aged manure and/or compost into the soil about 8 to 10 inches deep and rake it several times to break up the large clods.
- Put transplants into the ground once the soil temperature has reached 65°F (18°C). Speed up the warming of the soil by covering it with black plastic or a dark mulch about a week before you intend to plant.
- It is best to transplant peppers in the evening or on a cloudy day. This will keep the plants from drying too much and wilting.
- Make the transplant holes 3 to 4 inches deep and 12 to 18 inches apart in the row. Space the rows 2 to 3 feet apart. Before planting, fill the holes with water and let it soak in. Into each planting hole, put two or three wooden matchsticks (for sulfur) and 1 teaspoon of low-nitrogen, high-phosphorus fertilizer (too much nitrogen will reduce the fruit set).
- When pulling the transplant out of its tray or pot, be gentle and leave as much soil as possible around the roots. Set the transplants about 1 inch deeper than they were in their original container. Fill the hole with soil and pack it loosely around the plant. Leave a slightly sunken area around each plant to hold water.
- Water the plants after planting.
- Using liquid fertilizer material (manure tea, compost tea, or starter fertilizer) is usually beneficial at this time.
- Stake now to avoid disturbing the roots later. If necessary, support plants with cages or stakes to prevent bending. Try commercially available cone-shaped wire tomato cages. They may not be ideal for tomatoes, but they are just the thing for peppers. Or, build your own garden supports.

Types
Look for varieties that ripen to their full color quickly; fully mature peppers are the most nutritious—and tastier, too!
- Green peppers that turn Red: ‘Lady Bell’, ‘Gypsy’, ‘Bell Boy’, ‘Lipstick’
- Orange: ‘Milena’, ‘Orange Sun’
- Yellow: ‘Golden California Wonder’
Harvesting
- Once the plants begin producing fruit, pick them promptly: the moment they have reached their full size and color. Regular picking encourages plants to produce more flowers and, of course, more fruit.
- That said, the longer bell peppers stay on the plant, the sweeter they become and the greater their vitamin C content.
- Snip the stems of fruits with a sharp pair of clean pruners, scissors, or a sharp knife.
How to Store Peppers
- Peppers can be refrigerated in plastic bags for up to 10 days after harvesting.
- Bell peppers can be frozen for later use. See how to freeze peppers.
- Peppers can also be dried. Preheat oven to 140°F. Wash, core, and seed. Cut into 1/2-inch strips. Steam for about 10 minutes, then spread on a baking sheet. Dry in oven for 4 to 6 hours; turn occasionally and switch tray positions. Cool, then store in bags or containers in a refrigerator.

Cooking Notes
Peppers are excellent with almost anything: sandwiches, scrambled eggs, pizza, salads, and dips.
We also enjoy cooking peppers, whether in a beef stir-fry, as smoky roasted peppers, or in meat- and rice-stuffed peppers.
Plus, peppers can be pickled! See how to make pickled peppers!
A friend gave a hot pepper plant, about 5" in height. It had a what looked like one or two peppers beginning to form. I put the pepper in my box garden (1/3 compost, 1/3 peat moss, 1/3 vermiculite). The plant looks great, but the two the beginning peppers are gone. What did I do wrong I live in the Caribbean, so it gets lots of sun, and I water it everyday. thanks for your help.
Pepper root are very sensitive you may have disturb the roots it self or may still be in shock which is typically 7 to 14 days i believe good luck oh and i envy that your in Caribbean. as i am in canada and expecting a foot of snow tonight
I was wondering what ratio fertilizer to put in the holes with the match sticks? Should it be nitrogen free?
It should have some nitrogen. A 5-10-10 fertilizer works well for bell peppers.
I plan to grow bell peppers commercially through an outdoor hydroponic drip irrigation system. i live in North San Diego County and our night time temperatures average in the 40's through April. Because peppers can be damaged in below 65, do i need to wait to move my plants outdoors until April/May?
Yes, peppers go dormant when temperatures reach 50 degrees.
I live in the San Francisco bay area and I have two pepper plants that are still looking beautiful with lots of peppers on them (red bell) that haven't turned yet. It is nearly mid November and things still look great. How late can I leave them and what is the lowest temp they can withstand?
Peppers can withstand light frost, however, they will start to go dormant when the temperatures get down to 50 F.
Dumb question, but each season do you start from seeds again or if I keep my plant indoors during the winter months and bring it back outside during the spring/summer months will it produce more fruit?
Thanks!
No dumb questions in gardening! Peppers grow anew each season; they generally take 35 to 45 days to mature from flowering to full color. People do try to keep growing peppers over the winter but in most climates they would need a lot of grow lamps and heat to keep going; usually, the declining amount of sunlight slows them down.
