Why Are Pepper Flowers Falling Off?

There are several causes for excessive flower drop on pepper plants. We’ll go through some common reasons for pepper plant flowers falling off here.

Note: Some flower drop is natural. Pepper plants produce more flowers than needed to be more attractive to pollinators. This ensures that at least some flowers are fertilized.

  • High temperatures. One of the most common causes of pepper flowers dropping is high temperature. Although peppers can tolerate very high temperatures (100°F+), they thrive in moderately warm climates (around 70-80°F).

    As a result, heat waves can cause plants to become stressed. The result is often flower drop, drooping leaves, and more water usage.
  • Over-watering. Another mistake pepper growers often make is over-watering. Too much water in the soil is one of the biggest threats to a healthy pepper plant. It can cause a variety of issues, one being flowers falling off.

    Peppers require even watering throughout their entire life cycle. Water retention is better with healthy soil. Keep your soil happy and alive with organic material (compost, fish fertilizer, manure, alfalfa pellets, etc.).

  • Poor pollination. In order for a pepper flower to become a pepper fruit, the flower needs to be fertilized. This means that a grain of pollen must be accepted into the flower’s pistil.

    Typically, bees and other insect pollinators will take care of this naturally. However, if you are growing indoors or in an isolated location outdoors, pollination rates can be low.

    Try shaking the plants during flowering to encourage the release of pollen. Indoors, running a small fan can help, along with brushing the flowers by hand each day.
  • Excess nitrogen. Nitrogen is an essential nutrient for all plant growth. However, too much of it can cause plants to abort fruiting to produce more leaves. Instead, peppers use more potassium and calcium to produce healthy buds and fruits.

    For this reason, we recommend reducing fertilizer or switching to a low-nitrogen blend during the blooming stage of growth.

    Try Fox Farm’s Tiger Bloom for better fruit setting at this stage.
  • Phosphorus or potassium deficiency. On the flip side, without enough phosphorus or potassium, peppers may struggle to produce pods. The recommended fertilizers above should help correct any potential deficiency.
  • Inconsistent humidity. Humidity levels can decrease the viability of pollen grains. The ideal humidity will vary by pepper type. For example, New Mexican varieties prefer more arid climates, while superhot C. chinense varieties like higher humidity. Do some research on your particular pepper variety to learn more about its origins and what climate suits it best.

If none of the above issues are causing your pepper flowers to fall off, consider what else may be stressing your plants. Is it extremely windy? Is it raining too much? Too little? Were the plants properly hardened off when they moved outside? Any of these stresses could be your culprit.

Pepper Plant Growth Stages

It may be helpful to have an overview of the pepper plant stages of growth. First, the seeds will sprout into seedlings. During this stage, they require strong light for 16-18 hours per day. Seedlings are eventually transplanted into larger pots before moving outdoors in full sun.

Once pepper plants reach a mature size, they should begin to produce flowers. The flowering/fruiting stage is the ‘final’ stage of growth for peppers.

Each variety can produce a limited number of fruits at any given time. For example, bell pepper plants may only have 4-6 pods on the plant at a time. Aji charapita peppers may have hundreds of fruits on a plant.

When To Pick Pepper Flowers

If your pepper plants are producing flowers when they are too young, we recommend plucking them. The best way to avoid premature flowering is to upsize the plant’s container at the right time.

Evenly water and keep the soil fertile until the plants are outdoors in their final location. Stop plucking flowers after the plants have been in their final spot outside for 2-4 weeks.

Keeping Peppers Happy

In general, keeping your pepper plants healthy should reduce all major issues. This includes flowers dropping, but also yellowing leaves, curling leaves, diseases and pests, and so much more.

Here are some of our major recommendations for keeping peppers happy.

  • Enrich the soil. If you have ground soil, add compost, manure or other organic material every year. This keeps the good bacteria within the soil healthy, leading to better water retention, nutrient uptake and general plant health for your peppers. For potted plants, organic fertilizer will work.
  • Water evenly. Never water too much, and allow for water to drain away from the pepper’s root system. Soaking wet pepper plants will effectively drown, causing many problems.
  • Pick ripe fruits. Whenever your pepper plants produce a ripe pod, pick it. This will encourage the plants to continue producing until the season ends.
  • Watch for pests. Pests, like aphids, can wreak havoc on pepper plants. Keep a sharp eye out for pests and try to prevent them altogether by growing plants that attract beneficial insects to your garden.
  • Bottom prune to avoid disease. Keep the lower branches pruned back to stop soil from splashing onto your plants during watering or rainfall. Soil can be home to infectious diseases that can harm your plants. Staking and bottom pruning are great methods to prevent this.

  1. The flowers in my chili plants have started to come out only now (mid September). And, I see that the leaves are becoming weak (pointing downwards). Should I bring them inside or keep them outside?

  2. What about when the fruit sites do get pollinated, turn yellow & and grow a pepper and then the plant drops them, or odder yet when The whole pepper turns yellow, any idea what could cause that? I had perfect looking pepper plants then like 50-60% of my fruit sites all turned yellow and most fell off, and it was pretty much over night. It had been hot-ish but really just like 83 was the hottest. It’s definitely not pollination, we have thousands of bees butterflies hummingbirds and more right here where my garden is. Pretty frustrating after all the work and $ on fertilizers and time. Lots of time. It’s happened to a lesser degree to some of the eggplant plants as well.

  3. Excellent article on paper flowers for the dropping of excess flowers learned a lot

  4. When my pepper plants started frutting, the new leaves stopped growing large. What am I doing wrong?

    1. It’s normal in full sun for the leaves to be smaller. The early leaves are always much larger. Less light usually means larger leaves (the leaves get bigger to capture more light energy).

  5. Here’s a question i haven’t been able to find an answer to. I have two scorpion pepper plants that are doing a great job surviving the Texas heat, but i haven’t had a single pepper. They drop (assuming because of extreme temps. Will a pepper plant regrow a flower at one of the flower crotches (nodes?) if one has been there and already dropped? Or will it only grow flowers at new nodes? I know if i cut back a pepper plant and over winter it, new growth will generate new flowers. These plants are getting pretty large so i guess im asking do i cut them back now and try to spur some new growth before our long season is over, or let them go and assume only new growth will produce new flowers?

    1. You know, I have never actually tested this, but in my experience, most peppers seem to be able to re-sprout flowers from nodes. Some even produce multiple flowers from one node simultaneously, so I’d expect to see another flush of flowers once it cools off

    2. @peppergeek, I live in MN and damn even the ones I started indoors… My scorpion plants are small AF, really healthy, maybe some of the healthiest. But not even a foot tall, one is a foot wide, but they are definitely not going to make peppers. I plan to dig up the best 2 maybe 3 and bring them inside to spend couple of months indoors hoping to actually get my first scorpion peppers

  6. I didn’t get any seeds. I purchased them from Lowe’s like I do every year. in 2020 and 2021 they were in a raised bed and did great. I’ve purchased 5 separate plants this year. All of them are doing the same thing. flowering like crazy but not one pepper. I can see where the flowers are pollinated…and a day or two after the flowers petals fall off..the entire bud drops off.

  7. I’m about to give up. I have lost every single one of my flowers over the past two weeks. I recently had 3 fertilized baby peppers simply fall off two days after the petals fell off. I have no idea what to do. Temperatures have been in the mid to upper 80’s during the day and in the mid to upper 60’s at night. I give them around 6 hours of sun a day and have them sitting on my back concrete patio in 5 gallon plastic pots. I’ve used quality potting mix and quality organic fertilizer. Overall with three plants, I’ve only produced one measly reaper pepper. any thoughts?

    1. Where did you get your seeds? We have actually grown reapers where the flowers were not producing pollen. The plants were deemed “infertile” and they basically gave us nothing. Check a newly-opened flower to see if any pollen is falling from the anthers. If they don’t produce any pollen, and eventually just fall off, it may be the same situation. Try a new seed source next time :/

  8. In 2021 and 2020 I had reaper, ghost, and habanero plants in a raised bed. I bet I had 50+ peppers per plant.

    This year I have 3 black plastic 5 gallon pots. I got the same type of plants from lowes and planted in the pots. The first 4-6 weeks they barely grew. I threw out the soil and got new and fertilized this time. Plants finally grew.

    Now I’ve got flower buds everywhere but ALL OF THEM are falling off after pollination. I’ve also noticed that my ghosts leaves will start to droop after 30 minutes in the sun.

    Could my issue be lack of watering?

  9. Hi there, Peppergeeks… thanks for all your great information!
    I planted a lot of peppers from seed and got quite a few bell peppers but…
    1. Why are my peppers not as big as the ones in the shops?
    2. Do bell pepper plants produce peppers year after year after year? Or is the first year great, the second year poor and then nothing after that?
    Thanks for all your advice,
    Regards, Jim

    1. Hey Jim, so size comes down to the genetics of the plant, and the conditions in which they are grown. More light means bigger yields and often larger fruits as well. As for productivity over the years, yes they have the capacity to produce many years in a row. However, we haven’t overwintered any bell pepper plants personally, we just start new plants from seed. So I’m not exactly sure how yield changes in successive years

  10. I grow plants hydroponically and I grew peppers a couple of times. I experienced a lot of flower drops most likely because of excess nitrogen. I did not want to change nutrients (I only had 1 kind) so I kept feeding the same thing and had flowers dropping for a long time then suddenly they stop dropping and began setting fruit.

    Is it possible for peppers to adapt to the excess nitrogen conditions and begin setting fruit? or was I somehow lucky?

    I remember seeing your video (Fertilizing Peppers – All About Plant Nutrients – Pepper Geek) where you said “unless you live in the tropics where you don’t have to worry about the approaching winter you definitely want to reduce nitrogen about halfway”, since its hydroponics and don’t worry about winter, does that mean if you feed high nitrogen nutrients it will just take longer time to set fruits after experiencing flower drop like me?

    Sorry for the loaded comment this has always been in my mind and cannot find anything online to my questions.

    1. Hi there, it is more likely that the root mass of your plants filled out the reservoir and forced fruiting mode. Excess nitrogen won’t cause a plant to produce 0 fruits, but is known to cause reduced yields. I would still reduce nitrogen around the fruiting stage and increase your phosphorus/potassium. With hydroponics, this is easy, as they make specially formulated nutrients for the fruiting/blooming stage.

  11. I don’t have any comments but, I have a problem with my lemon drop pepper.This morning I found that the leaves, flower and fruit falling off. The leaves are green, the flowers and fruit looks healthy. What can be the problem?

  12. We’re in the middle of some nasty storms and I noticed that the weather may have knocked some of the blossoms off my plants but there’s still a bud present. Where the flowers came off I can see a little tiny pepperling starting to come in on some of them. Will they still grow OK?

    1. Hm, good question – In our experience, no. However, the plants definitely need a more regular supply of water to get through a heat wave.

  13. Here in Phoenix the temperature is over 100 degrees. I had to put shade screen over my plants. will this hurt peppers from growing ? I also spread straw on the ground around my plants to hold the moisture when i water. Is this ok ??

  14. I have a few Shishito pepper plants out side in the ground. About half of the peppers are red even before they are ready to pick. what am I doing wrong? They are still good but some dry out quickly.
    Thanks, Leo

    1. When they turn red, they are ripe, shishitos will ripen some peppers earlier than other, so I’d recommend picking them when you’re ready to eat!

  15. Started my red chilis from a store bought pepper. Germinated a handful of seeds in Miracle-Gro potting mix/coconut coir media fortified with 3-4-8 tomato fertilizer in a lidded coffee canister. 10 days and all seeds sprouted. Moved them to 2 gallon buckets in a partially shaded area of my balcony. No hardening off as I live in S. Florida. Watered every day, just enough to keep media moist. Plants flourished and soon had them in full sun 6-8 hours a day. once they reached a height of @ 8″ the iguanas discovered them and devoured them leaving mostly stalks, stems, and half eaten leaves. Purchased 2 items that day: 1) Chicken wire and 2) a scoped air rifle. Plants are thriving, lush, and loaded with flowers now and iguanas have disappeared (I’m a good shot…lol). I switched to Miracle-Gro Performance Organics fertilizer (11-5-8) at half strength. My problem is flower drop. I’m thinking it’s the heat (83 +) and humidity (60% avg) that’s causing it. Would bringing them inside after sunning to a 74 degree/ 30% humidity location help the flowers set more easily?
