Growing Bell Peppers

Planting, Growing, and Harvesting Bell Peppers

Rate this Article:

Peppers are a tender, warm-season crop. Here’s how to grow peppers in your garden!

Peppers resist most garden pests and offer something for everyone: spicy, sweet, or hot; and a variety of colors, shapes, and sizes. For this page, we will focus on sweet bell peppers.

Planting

Start seeds indoors 8-10 weeks before last spring frost date.
The temperature must be at least 70° F for seed germination, so keep them in a warm area for the best and fastest results.
Start pepper seeds three to a pot, and thin out the weakest seedling. Let the remaining two pepper plants spend their entire lives together as one plant. The leaves of two plants help protect peppers against sunscald and the yield is often twice as good as two segregated plants.
Begin to harden off plants about 10 days before transplanting.
A week before transplanting, introduce fertilizer or aged compost into your garden soil.
After the danger of frost has passed, transplant seedlings outdoors, 18 to 24 inches apart (but keep paired plants close to touching.)
Soil should be at least 65° F, as peppers will not survive transplanting at temps any colder. Northern gardeners can warm up the soil by covering it with black plastic.
Put two or three match sticks in the hole with each plant, along with about a teaspoon of fertilizer. These give the plants a bit of sulfur, which they like.

Care

Soil should be well drained, but be sure to maintain adequate moisture either with mulch or plastic covering.
Water one to two inches per week, but remember that peppers are extremely heat sensitive. If you live in a warm or desert climate, watering everyday may be necessary.
Fertilize after the first fruit set.
Weed carefully around plants.
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.
For larger fruit, spray the plants with a solution of one tablespoon of Epsom salts in a gallon of water, once when it begins to bloom, and once ten days later.

Pests/Diseases

Aphids
Flea Beetles
Cucumber Mosaic Virus
Blossom-End Rot appears as a soft, sunken area which turns darker in color.
Pollination can be reduced in temperatures below 60° F and above 90° F.
Too much nitrogen will reduce fruit from setting.

Harvest/Storage

Harvest as soon as peppers reach desired size.
The longer bell peppers stay on the plant, the more sweet they become and the greater their Vitamin C content.
Use a sharp knife or scissors to cut peppers clean off the plant for the least damage.
Peppers can be refrigerated in plastic bags for up to 10 days after harvesting.
Bell peppers can be dried, and we would recommend a conventional oven for the task. Wash, core, and seed the peppers. Cut into one-half-inch strips. Steam for about ten minutes, then spread on a baking sheet. Dry in the oven at 140° F (or the lowest possible temperature) until brittle, stirring occasionally and switching tray positions. When the peppers are cool, put them in bags or storage containers.

Recommended Varieties

Look for varieties that ripen to their full color quickly; fully mature peppers are the most nutritious—and tastier, too!

Green to Red: ‘Lady Bell,’ ‘Gypsy,’ ‘Bell Boy,’ ‘Lipstick’
Yellow: ‘Golden California Wonder’

Wit & Wisdom

The popular green and red bell peppers that we see in supermarkets are actually the same thing; the red peppers have just been allowed to mature on the plant longer, changing color and also gaining a higher content of Vitamin C.

1st timer w/Bell Peppers

So i grew out some bell peppers which I transplanted in to 1 gallon pots.
Situation is this: I live in an apt, & I only had a couple gallons so I transplanted the best 16 plants into 4 pots of a gallon thinking I could transplant when they got bigger BUT the started to bloom flowers now.
I never thought they would get so tall & have such big leaves (sorry 1st timer on this). So the thing is they started blooming flowers but the flowers are drying up after 2 days or so.
They are getting at least 4hrs of direct sunlight, they are watered & well drained, also I helped with pollination process since they are kept inside, so I have no idea whats going on. could it that they are crowded? , Could you shed some light?

early blossoms

Early flowering in peppers sometimes happens. Some gardeners leave the flowers alone, but others prefer to pinch the early blossoms so that the plant can focus on developing a good root system before focusing on fruit production. Blossoms may drop if the plant is stressed, such as too hot (above 85F or 90F day) or cold (below 60F night), or not enough or too little water. Peppers are particularly sensitive to temperature, and like daytime temps of around 70 to 80F. Transplanting may also stress the plant for a little while, but they should recover. Petals of a successfully pollinated flower will drop after a few days–look just near the area of the petals to see if a little fruit is forming. Hope this helps!

Aliminum foil

Is using strips of aliminul foil as a ground cover under pepper plants really beneficial to the plant? Does it really help in any way?

Leaves on pepper plant shrivel and die

What to do?

pepper problems

There are so many reasons why a pepper plant’s leaves shrivel up. Is it getting enough water? The topsoil should be moist a few inches deep (use your finger to reach down). Are you overwatering? Soil should never be soggy. Is it too hot? Peppers like heat but if it’s consistently super hot, you may need to give them shade cloth at the peak of the day. Finally, there are pests and diseases. Aphids and thrips are especially bothersome. You need to spray soapy water in the morning or Neem oil or speak to your local garden center about another solution.

Pepper Degree Days

Hello, I have a small farm in the Fresno area. I have been looking for information on growing growing degree days for Bell Peppers and how they coincide with phenological growth stages. Does anybody know the answer to this?

Peppers with thin walls

I grew Peppers last summer and they did very well. They produced pretty well but they don't have as thick of a wall as the ones I get at the store. I live in Wyoming - high elevation (over 5,ooo ft). Is there anything I can do to get thicker walled peppers?

How to Grow Thick-Walled Peppers

Hi Megan,

The two most important factors that can affect growing peppers with thick walls are the days to maturity and the amount of water given. If peppers are not given adequate time to reach full maturity, they will have thin walls: this is especially noticeable in hot regions. Try not to be impatient when waiting to harvest your peppers and it will pay off. As for water, the growth of peppers can be drastically influenced by an inconsistent watering schedule. Peppers like well-draining moist (not wet) soil, so be sure to water pepper plants evenly and consistently, and to water more or less only when temperatures or humidity change drastically, as they will affect the amount of water evaporating into the air. Good luck with your crop of peppers this coming growing season!

BLOSSOMS FALLING OFF

I have a lovely Purple King pepper plant that I brought inside to keep growing... trimmed back, it is producing flowers, but a few have fallen off without forming any peppers--- they were growing in a large container, so I did not transplant-- the indoor garden is heated, and also growing lights are in use...watering well, and not drowning the roots... what am I doing wrong, please?

blossom drop

Peppers can drop their flowers for a few reasons, including temperatures that are too cool or hot, inadequate pollination, or some other cultural stress, such as too little or too much water, humidity too high or low (which can affect the pollen), soil too rich or nutrient-poor. Sudden changes in temperature, such as what might happen when moving them indoors, can also stress the plants. Some insect pests and diseases can also cause flowers to fall off. Best guess, since your plants seem otherwise healthy, would be that your plants are either just adjusting to their new environment and should eventually recover, or the flowers aren’t receiving enough pollen (peppers are self-pollinating, but wind or insects help the transfer of pollen). Since your plants are indoors, away from wind and insects, you might try gently shaking the plant a tiny bit, to mimic wind, to encourage pollen to fall onto the flower stigmas. Or, you can gently gather pollen onto a cotton swab or small paint brush (just brush the pollen-coated anthers of the flower) and then transfer the pollen to the flower stigma, in the center of each flower. Hope this helps!

New peppers in Sept.

I planted a red bell plant late May.._I live in Northern Indiana , and we´ve had a strange Summer this year.._3 weeks ago we had an outburst of humid weather in the 90s for just over a week, and now i have floers i thought were nearly dead and reblooming ._.The strangest thing is the pepper plant,it produced 5 peppers all Summer,2 of which didnt make it.._half of the plant died mid Aug. ,so i cut it away hoping for the best. 2 weeks ago the plant started growing new leaves and I counted 24 new peppers growing on half of a plant!._.Everyone I know says their garden is shriveled up.._is there an explanation for this?

Peppers in Fall

If the weather’s been especially hot (which peppers prefer), the peppers may have thought that it was Summer Part II and thus, time to produce more peppers! It’s unlikely that they’ll make it to full maturity at this point in the season, but you could try to give them a couple extra weeks by employing row covers.

I live in central Indiana and

I live in central Indiana and had a similar experience this summer. I potted two bell pepper plants. One produced 5 peppers all summer, the other only 3. That is until the humid heat wave. Both plants began to rapidly bloom, and I currently have 20+ peppers on each plant.

Turning green to red

How long does this usually take? I have a green pepper that shows no sign of turning red after at least two weak.

huge error

Make hat two weeks, sorry. I'm in the Boston area if that matters

bell pepper ripening

How long it takes a bell pepper to ripen to red depends on the variety, temperature, and other conditions. In general, it may take 2 to 4 weeks or more, once the pepper reaches mature size.

Epson salt

Is it possible to use too much Epson salt? I did not use any at the beginning stages of my peppers and tomatoes. They are now a bearing fruit. I have got Epson salt now and have started adding it to the soil water and the leaves. I read that I should only do this every 10 days or so, but I am doing it more often because I never did it before. So, I am wondering if too much at this point would hurt the plants or what?

Epsom salt

Instead of using match heads under peppers, use a pinch of epsom salt (Magnesium sulphate). Match heads provide sulphur as does epsom salt. You can make a solution of E.S. and water for foliar feeding as well.

green peppers

I have a lot of green pepper plants,when I harvest the peppers,can I freeze them in bags??

freezing peppers

You can certainly freeze peppers, but it’s recommended that you do a little prep work beforehand. Wash the peppers and dry them, cut off stems, split each pepper in half, and remove the seeds. Then cut into slices, if desired. Spread the pieces on a tray, so that each piece does not touch any other, then place in the freezer for about an hour or so until frozen. Then remove the tray and place the frozen pieces in a dated and labeled zipper freezer bag, squeezing out as much air as possible, and place in the freezer.

Weed or plant

How can I tell if what I have is my bell peppers or a weed

Red bell peppers

I have a plant with peppers set on. They are in full afternoon sun and on a drip system. One side of the pepper is withered and the other side is still plump. Too much sun, water?

pepper problem

Insects and diseases might cause such symptoms, but it may actually be sunscald. Bell peppers are susceptible to sunscald, which occurs during high temperatures, especially during humid conditions, and direct exposure of the fruit to sunlight during its development. It can appear as faded, papery, blistered, or gray-white sunken areas on the fruit on the side that has been exposed to the sun; the areas will later dry and possibly develop black mold. It is best to have the fruit develop under the leaves; you can provide shade cloth or use row covers to help protect them. Staking plants as they grow also helps fruit to remain under the leaf canopy. Good watering and fertilization at the appropriate times help to develop a good canopy. Hope this helps!

Yellow and Red Pepper

I am growing these peppers in pots on my balcony. I bought then already about 12-15 inches high and planted them in a small pot....too small. They are growing really well however, I am wondering if I should move them to larger pots. There is one plant in each plant and I had little green peppers already on one but am wondering is it ok to transplant without killing now?

Transplanting bell peppers

It’s OK to keep “potting up” peppers are they grow. They’re quite adaptable. That said, we usually stop transplanting peppers once they have flowers and fruit as the fruit and blooms may die with transplanting. A 3 gallon pot (14-inch diameter) would be suitable for a couple pepper plants.

Planting Peppers - Spacing question

I am planting sweet peppers for the first time. I planted them 12 inches apart. now I read they need 18-24 inches space. they are growing nice and tall but are not growing any fruits yet. can I still remove some plants without damaging other roots? what should I do?

Pepper Spacing

Hi Bella,

The 18 to 24 inches of space is a recommendation. 12 inches between each plant should be plenty, so don’t remove any plants. As long as the area where your pepper plants are growing is in full sun, you should be fine. Thanks for writing!

Any tips on how to deal with the desert sun?

growing peppers in the desert

Peppers are heat-seeking vegetables which are well suited for desert climates. That said, some pepper varieties do better than others. Jalapeños do the best, especially when grown in full Sun. Ancho and sweet banana peppers do very well, but produce even more yield when grown under shade cloth. In desert regions at around 4,000 feet of elevation, sweet bell peppers often fail to develop a thick fleshy wall, especially upon ripening, and their quality can be poorer than store-bought bells.
