How Many Bell Peppers to Expect Per Plant

Bell peppers are large fruit that typically measure 3×4 inches. Compared to other types of peppers that can yield 100 peppers per plant, bell peppers will yield a smaller number per plant but the yield in weight will be similar.

The main factor in how many bell peppers to expect from one plant is the size of the bell pepper plant. A bell pepper plant can vary big time in size depending on how much time the plant has had for vegetative growth before fruiting. Expect anywhere from 2-30 bell peppers from a single plant.

bell peppers per plant in a greenhouse
Bell pepper plants in greenhouses have a longer growing season than bell pepper plants started outside. They are pruned and trained up twines and regularly grown with two main stems that will reach over 10 feet tall. These bell pepper plants are producing around 12 bell peppers per plant.

The main cause of poor bell pepper yields is a lack of growing time. A bell pepper plant started outside with only 3-4 months to grow and produce fruit is likely to only grow to about 1.5’x1.5′ and produce only a couple bell peppers.

Grow Bigger Bell Pepper Plants for More Bell Peppers – 2 Different Ways to Overwinter Them

The best way to avoid having a small bell pepper plant is to start seeds indoors and give the plants an extra 4-12 weeks for vegetative growth. By doing this the bell pepper plant should be able to reach at 2.5’x 2.5′ and produce 5-10 good sized bell peppers in a season.

After transplanting the bell pepper plants outside watch the plant carefully for flowering. If the plant produces any flowers within 4 weeks after transplanting outside pick the flowers off so that the plant stays in a vegetative growth state. After four weeks if it starts to flower let it be.

Bell peppers are scientifically classified as Capsicum annuum, but contrary to that classification they are perennial plants that can live for 2-5+ years.

This bell pepper plant was overwintered in a large south facing window by a friend. The bell pepper plant started producing bell peppers before it was moved outside towards the end of May.

To get a plant that produces the most amount of bell peppers possible you’ll need to overwinter the plant. There are two ways to do this, with supplemental lighting and without. The one way the bell pepper plant will continue to grow through the winter and the other it will go dormant and wait until the spring to begin growing again.

Without supplemental lighting or a warm area with large southern windows you’ll want to leave the plant outdoors while temperatures drop and take it in just before the first frost to help it enter a dormant stage naturally.

Before bringing it inside heavily prune the plant to 1/2 or 1/3 of its size. The plant will enter a dormant stage and become bare and naked of leaves like a tree in the winter time.

Once spring comes around break the bell pepper plant out of its dormant state by giving it more light and higher temperatures. If successfully overwintered the plant will pick up where it left off and produce more bell peppers with a longer and earlier fruiting period.

To get the absolute most bell peppers per plant you should overwinter the bell pepper plant with supplemental lighting. This should produce a 6×6 foot behemoth plant after a year of growing that will produce 20 or more bell peppers in a season.

This grower and youtuber uses supplemental lighting in his indoor garden. Skip to 13:00 minutes in to see peppers on the plants.

A little bit of supplemental lighting should keep the plant growing minimally and you don’t need to prune it back much. A more serious indoor light can keep the bell pepper plant flowering and producing peppers all winter.

If you really wanted to push the limits on production per plant and have a pot big enough to do so I think you could take it quite a bit further.

In greenhouses bell pepper plants are grown in a “V” system where they are topped once and have two main stems. The two stems are run up lengths of twine and regularly grow over 10 feet tall. Here’s a super in depth article on greenhouse bell pepper production.

How Long Do Bell Peppers Take to Grow?

Grown from a transplant most bell peppers will have green bell peppers that are full size and ready to pick after 60 days and will reach full ripeness and their final color within 90 days. Bell pepper plants grown from seed will take 120-150 days to harvest.

Seed companies usually list days to maturity for bell peppers as transplants that have been started indoors for 8-10 weeks. The 60 days from transplant or 120 days from seed is how long until the plant takes to produce full size immature bell peppers. The 90 or 150 days is how long until the bell peppers on the plant change color and reach full maturity.

Almost all bell pepper varieties start out with immature green bell peppers that grows in size until they reach around 3×4 inches. After the bell pepper reaches its full size it will take 3-4 weeks for it to turn color and become fully ripe. After flowering starts expect around 8 weeks for fully mature and ripened bell peppers to appear.

Bell Peppers Per Plant vs. Total Yield vs. Plant Spacing – Commercial Production

In commercial production farmers are most concerned about the total yield of bell peppers by weight. Studies are done on almost all types of produce to determine the optimum plant spacing for best total yields.

In general, plants spaced further apart will have more fruit per plant and bigger fruits than fields planted with higher plant densities. But the field will have a smaller yield by total weight than a field planted with higher plant densities.

Sweet peppers, including bell peppers, are the same. A study published in the African Journal of Agricultural Research planted Nsukka yellow peppers with 8 different plant spacings the tightest 6×24 inches and the most spacious being 30×24 inches.

The most spaced plants grew 110 peppers per plant while the highest plant density yielded 38 peppers per plant. However, the total yield by weight was the opposite. The most spaced plants yielding just over 1 kg per plot of land planted and the highest plant density yielding 3.5 kg per plot of land planted.

Do Bell Pepper Plants Keep Producing?

Bell peppers are perennials that will keep producing. Commercially, I found no evidence of bell pepper plant production year round. The cost of supplemental lighting and pests would be the biggest deterrent for this. They might be doing this in areas closer to the equator with good sunlight year round.

In the video towards the top of the article the grower is definitely having success growing his bell pepper plant indoor with great vegetative growth and a decent amount of pepper production.

He states in the video that he usually likes to keep the plants in vegetative growth while indoors. He would do this by giving them different light schedules or by pruning off flowers. I’ve watched a few of his videos and didn’t hear him say exactly how he does it. He’s a little bit of a mad scientist.

The video below is a great video where the grower states that he does get peppers from the same plant multiple times but that he needs to trim the plant to create new growth that stimulates new fruit production.

So he trims the plant back aggressively and then harvests about every 3 months. He also grafts different pepper varieties onto one plant.

Increase Bell Pepper Yields

Start Bell Pepper Plants Indoors – This is common practice with bell peppers and a must to increase yields. In areas with a short growing season outside of only 4 months or so the 8-12 week start indoors can lead to 2-3x yields at the end of the growing season.

Make sure to pick flowers off of the bell pepper plants in the first 4 weeks of transplanting it outside to keep it in a vegetative growth state during the early outdoor season.

To start bell peppers or anything else indoors I recommend using compostable starter pots that can be transplanted directly into the ground to avoid any shock during transplant.

Cardboard egg cartons can be used to start plants by putting a few toothpick sized holes in each of the egg spots and the top of the carton underneath it. Cut the egg carton into individual pieces when transplanting and sometimes you have to pull that apart a little if it hasn’t disintegrated enough.

Hand Pollination – By hand pollinating you’re doing what you can to give each and every flower the best shot at becoming a fruit. Bell peppers have what’s called “perfect” flowers, meaning a single flower has both male and female parts. Plants with “perfect” flowers are self-pollinating.

Still, there are causes for low pollination. If your peppers are in an area where they are sheltered from the wind the lack of branch movement can cause low pollination. To hand pollinate, take a paint brush and swirl it around the inside of the flower or try this thing that looks like an electronic toothbrush.

Big Enough Pot for Potted Plants – For potted bell peppers give them a pot with 12 inches of depth and at least 3 gallons of dirt per plant to grow in.

Prune Plants – If you know that you want to keep the plant for multiple years plan on topping the plant once or twice to give it 2 or 4 main stems and a real bush build. If you decide to keep the plant late in the season it’s not a big deal and pruning as a whole around the plant will direct growth back into the existing branches and make a bushy plant with thick branches anyways.

Prune the bottom of the plant completely 6-12″ from the soil to discourage disease. Later in the season when bell peppers are near their full size you’ll want to take off leaves that are blocking direct sunlight from the peppers to hasten ripening.

Avoid Extreme Temperatures – The right temperatures for bell pepper plants is 65-85 degrees. Regular temperatures above 90 degrees can cause flower drop and little/no fruit and temperatures below 60 can do the same.

If you have a heat wave coming be sure to water more frequently and shading the plants with a shade cloth or tarp during the hottest hours of the day is a good idea.

Provide Good Soil – To improve your soil organically add compost to it every year when you’re done gardening for the season. Call your local city government to get access to huge amounts of compost piled up from the city collecting leaves and grass clippings.

Adding compost to the soil makes it more loamy. Sandy soil drains to freely and doesn’t retain water or nutrients; clay soil gets compacted and doesn’t drain well. Loamy soil has the right texture to allow water, roots, and air to pass through it freely but still retain moisture and nutrients.

Beyond giving soil better texture compost also adds nutrients and beneficial bacterias to the soil. To check your soil PH and nutrient levels you can do a soil test.

To fertilize Jack’s Classic is a great standard all purpose fertilizer. Organic Plant Magic and Garden Tone are good all purpose organic fertilizers.
