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!

This would be my first year growing bell peppers in my garden. I bought a ready to transplant starter in a 4in. container at my local Home Depot. I waited about a month until I finally transplanted my pepper to a 12in. pot. It gave me many blooms however they are all nowgrowing very close and are being smothered by one that is 4x bigger than the rest. I did add fertilizer to encourage it to grow taller but so far nothing. Is this normal? Will it affect the quality of the peppers?
I’m not sure that I understand the setup—are there several pepper plants in one container, one plant being far more advanced than the others? Or, are they all now planted out in a garden? As the above article suggests, two seedlings grown together seems to work well, but otherwise it is best to space plants 18 to 24 inches apart; you might want to thin them out a little, by snipping at the base (don’t pull plants up, to avoid disturbing roots of plants you’d like to keep). Fertilize when transplanting, and then after first fruit set. Be careful not to give too much nitrogen, which encourages leaf growth over flowering, until the peppers are developing. If you have lots of flowers but no fruit, you might try hand pollinating to help things along,
last growing season, I had some bell peppers in the beginning of the season start off great but then get to a certain size and suddenly a large brown "spot" started growing on them. I thought maybe they were getting too much water, so I changed the water pattern but it was still happening. The spots were more of a rot look than a blemish. I didn't eat them because they were ugly-which scared me! What happened to my bellpeppers?
It’s hard to know what it might be, as there are several things that can cause large brown spots on fruit. However, I’m wondering if it might have been anthracnose; for more information about this disease, see: http://www.almanac.com/pest/anthracnose and this article from the Ohio Cooperative Extension:
http://www.oardc.ohio-state.edu/sallymiller/Extension%20Outreach/information%20transfer/Factsheets/Vegetable/Anthracnosepepper.pdf
which shows you a picture of it on bell pepper fruit.
Some other possibilities might include:

Hope this helps!
I am growing seedlings from the actual Capsicum, and have them near a window in the kitchen, they are in a seedling tray, there are about 26, and are 6cm tall, my question is:- Should I put them into a large pot or let them grow a lot bigger?

Good morning,
I submitted a question to you on 26 February 2017, but have just realised that you are in England, and I am in Sydney, Australia, our climates are very different!! My apologies, I will try one of our sites.
Regards,
Loretta
I recently started pepper plants from seeds using peat moss pellets and a windowsill "greenhouse"/tray. Most of the seeds have sprouted and I am leaving them on the windowsill for the day and under a desk lamp at night. My question are: is the desk lamp sufficient for supplying light and to a lesser extent heat? Do I need to transplant the peppers from the peat pellets to a pot before hardening off and planting in my elevated bed, or can I keep them in the pellets until transferring to the bed? (P.S. I put casters on the garden bed so that I can roll it into the garage at night in order to avoid frost and major temperature drops. I assume this will allow me to transplant sooner assuming the soil temp remains above 65--I live in the deep south, MS). Thanks for any help you can give.
You can keep your pepper seedlings in the peat pellets, to help minimize transplant shock (they are especially good for that, since you can plant them pellet and roots together in the ground). If you do not plan to transplant them out directly in the garden for several weeks, you might consider at some midway point between now and then, transplanting the seedling (including its peat pellet) into a larger pot. Otherwise, wait and plant outside directly, after hardening off. As to the lighting, seedlings usually need about 12 to 16 hours of light. Make sure that your desk light is not on constantly overnight—use a timer. It would be better to use a grow light that offers the spectrum needed by plants, or a fluorescent shop light. The windowsill and desk lamp (if using a regular light bulb) may lead to thin, elongated stems. If there is no other option, though, adjust the lamp so that it is close to the seedlings, but not too close to cause any heat damage. Keep rotating your plants every day, even twice a day, so that the stems do not grow in one direction (toward the source of light). Good luck!
A hard freeze is coming, should I pull my bell pepper plants as I do tomatoes, or pick them individually?
It’s up to you. Some gardeners pull the whole plant and hang it upside down in a basement or garage, while others just harvest the ripening peppers. The fruit can be placed in a paper bag with an apple to help hasten ripening, if you prefer. If you have lots of peppers that are not up to full size yet, you might try pulling the whole plant in case the plant can still give the fruit a tiny bit more nutrients before the plant dries. But if your peppers are mostly of a mature size, then just harvesting the peppers themselves should work fine.
