The site and season: Where and when to grow Carolina Reaper

As with most super hot peppers, you are better off starting your Carolina Reapers indoors. Move seedlings outdoors once there is no danger of frost damage and they have grown to a height of at least six inches. You will want to do this only after daytime temperatures average about 70 degrees Fahrenheit and the temperatures at night are no longer dipping below 50 °F. Like most peppers, Carolina Reapers do best in warm weather but have little tolerance for weather above 85 °F. Overly hot weather can cause them to lose blossoms and stop producing fruit.

Carolina Reapers prefer soil with a pH of approximately 6.5.

If you are growing your Carolina Reapers in a container, note that 3 gallons is the minimum container size but is not optimal. Ideally, you will want to place them in a 5-gallon container or they may not be as productive as they can be.

Feeding and watering Carolina Reaper plants: How often and how much

Fish emulsion or 5-10-5 fertilizer is fine for fertilizing your pepper plant. Start fertilizing only after your Carolina Reaper has started showing blossoms. You should also provide your pepper plant with magnesium in the form of Epsom salts. You will want to avoid fertilizing with high-nitrogen fertilizers; these will not be beneficial for fruit production.

Provide the pepper plant with about 2 inches of water weekly, but decrease that amount once there is fruit on the plant. Water stress can help to increase the heat of your peppers.

Carolina Reaper harvesting: When to pick

You can pick your Carolina Reapers while they are green, but you will get more heat and flavor from them if you wait for them to ripen. Reapers will turn bright red when they are ripe.

Note that these are very hot peppers, so it’s best to handle them carefully. Consider wearing disposable latex gloves when harvesting. Otherwise, you may experience one wicked case of chili burn from the oils of these peppers (even from just handling.) Learn how to treat chili burn prior, too.

Carolina Reaper plant care: What to watch out for

Mosaic is a common pepper disease spread by aphids and whitefly. Pepper mosaic results in narrow, thickened leaves. In plants that are severely affected, the only real remedy is to pull the plants up and dispose of them to prevent healthy plants being infected. To control an aphid problem, you should consider getting ladybugs as these are predators of the aphid. Learn more about combating aphids here.

Other control methods include spraying with water to remove them manually from the plant and the use of insecticidal soap.

Read our Carolina Reaper comparisons

Our Showdowns compare two chilies, head to head on heat, flavor, and uses. How are they similar? Different?

  • Versus ghost pepper: The Reaper and the ghost are two of the most well-know super-hot chilies on the planet. But there are a few notable differences, especially in heat.
  • Versus habanero: The habanero is certainly spicy, but nowhere near super-hot heights. How different is it from a Reaper? Take a look.

Can you give a little more direction on fertilizer, brand names that you have had success with , amounts added during bloom , and how to apply this to the plants. I’m a newbie …. Thanks

Keith Chuter

Very informative Thanks

I’ve grown Carolina Reapers since last year using 5-gallon containers, with great success. I can tell you, though, that these plants are very susceptible to cross-pollination with other varieties of pepper. So, if you live in an agricultural area where peppers are grown, or even if your next-door neighbor is growing a few different peppers outdoors, there’s a good chance that your Reapers will get cross-pollinated and produce odd hybrids that look nothing like the classic Carolina Reapers. In my case, one of my neighbors was growing a couple of varieties of mild hot peppers, and we inadvertently cross-pollinated a… Read more »

Here is my Reaper at 45 days from seed under lamp.

Christopher Ridler

I have a friend who was growing some reapers for me. Unfortunately, he didn’t harvest them and we had our first freeze a few nights ago. The peppers are pretty wrinkled and soft now, but the coloration is still really good.

Are they still good to make a hot sauce with?

Mike Sakara

Since when is water measured in inches?

Ben Muriro

i got Carolina seeds and planted them in Uganda a some months ago.
My yield although indeed very hot changed shape completely. The shape is our ordinary small long peppers we call “Kamurali” and not the shape I see online.
I have been told it is a result of Cross Pollination which I cant confirm yet.
The hotness confirms to me that it is indeed Carolina as our ordinary Kamulari is not that hot otherwise I would have thought that I was given fake seeds

Phil Szmania

I haVe a carolina reaper plant which I have moved indoors. The plant is still green and has small peppers on it. All the leaves are gone. Can I revive the plant and how do I help it stay alive.

Quang Nguyen Minh

I live in Vietnam. I planted this carolina reaper for 5 months. It has a lot of blossoms but just 2 or 3 fruits. Can anyonne help me to produce more fruit? It is full sun and the weather is about 80°F – 95°F. I fertilize it with the following ingredients: N: 12 % ; P2O5: 12% ; K2O: 17%; S + CaO + MgO: 9%; B + Cu + Zn + Fe + MN + Si ≥ 0,4%

Thanks

Hello
I live in the U.K and purchased some reaper seeds of the internet. Temperatures are lower here some the growth process was slow. But I’m starting to think I got ripped off and these aren’t reapers. They don’t resemble the angry looking reaper. But this is the first time I have ever grown any. What do you think they are ? Will they start getting all gnarly looking ? How much longer shall I leave them before picking as autumn is apron us and temperatures are dropping fast.
Thank you.

I live in the Midwest, and I purchased a plant in a pot. $4.00. I was like Ok? lets see where this goes. That was June 29th, the plant was about 10 inches tall. It is now about 14 inches tall, flowers and peppers every where. I have just watered them, and have not added any kind of fertilizer , I will be adding Epsom salt today. My question is, I will want to keep this plant alive, so there for be bringing it in during the winter. Would a grow light help the plant live healthier ? I keep… Read more »

morrey L counterman

my plant is doing really well. My question is that it says not to over water. My plant is about 4 feet tall with around 200 mostly green peppers. Should I keep it watered more than the two inches a week to allow for growth of this much fruit? I’m in oklahoma temps are around 95 right now.

Uhclem

I seem to remember reading that terroir applies to peppers as well as to grapes and hops. So, in order to get premium results, these (or any) peppers must be grown in the original climate and soil conditions. Any thoughts on this? Also, it could be possible to get hotter peppers with the right terroir.

F or C? Like what temperature measurements, are we talking about here.

Bob DeSmit

Hello I successfully grew the Carolina Reaper last year. It made it through the winter and now I have a Woody stem plant and no leaves. Does it grow again for a second year or third year or do I start a new plant please help thanks Bob

Damian

I bought 2 plants they got about 2-3 feet with lots of flowers. one made flowers then peppers(4 in all on one plant) then flowers again but looks like it is about to die now. The other just flowers and is still healthy looking. I live in southeast Texas. Temps have been over 95 degrees maybe even the 100s. I am calling this a success. Just picked the first peppers today.

Mike

I live in Hawaii, and as I’m sure you can guess, the climate is tropical and humid. Usually very sunny and around 85-90 during the day, and cool (65-75) and humid at night. I planted 4 each: Carolina Reaper, Trinidad Moruga Scorpion, Naga Viper, Kraken Scorpion. It’s been about 2 weeks, and although I think I may have over-watered, The Trinidads have sprouted, and the reapers and others don’t look to be too far behind. Any tips moving forward from someone with experience in a similar climate?

Carlos

So, I live in Michoacán, Am I going to have problems with the maturation of my plant?

Logan Mason

So my plant was inside over winter, and i put it back outside a few weeks ago, and they just started blooming flowers. My plants are about 1 foot and a half tall

Jacquie

I read that they do not do well indoors.

I find your “A to Zing” very informative. I bought seeds from EBAY about a month ago and when my order arrived, I started to germinate the seeds. I placed 4 per paper (origami) box, ended up six boxes, placed all six in big plastic (like shoebox) container so I may transport them in and out the deck in one carry. I use water spray bottle the wet the soil when I notice the paper box are dry. I hope I started the right way!. I live in Mississauga (Ontario, Canada) where winter can be a hassle clearing my driveway,… Read more »
