How To Grow Peppers - 10/20-10/26/2025

You love peppers, and I do too. The crunch of a sweet bell, the kick of a jalapeño, the citrus heat of a habanero—it’s all garden gold. In this guide, you’ll learn how to grow peppers of all kinds including bell and other sweet peppers as well as serrano, habanero, jalapeno, and other hot peppers.

We’ll keep it simple and practical for American backyard gardeners. You’ll see how and when to plant in spring and fall. You’ll also learn the key differences between sweet and hot peppers.

Quick truth first: peppers love warmth. They hate cold feet and cold nights. If you remember that, you’ll already be ahead.

When I first started, I planted too early and lost half my peppers to a chilly night. Now I wait for the right soil and air temps. My plants thank me with big harvests.

Sweet vs. hot peppers share the same basic needs. Both need full sun, warm soil, and steady water. The differences show up in timing, container size, and a bit in drought and heat tolerance.

Is it easier to grow sweet peppers or hot peppers from seed? For most beginners, sweet peppers and jalapeños are easier. Habaneros and super-hots are slower and fussier, so they need an earlier start and more heat to germinate.

Grow Peppers: How To Plant

Start seeds indoors 8–12 weeks before your last spring frost. Hot pepper seeds often germinate slower than sweet pepper seeds. A heat mat speeds everything up.

Use this temperature rule. Germination is best at 80–85°F. Growth is best with days around 75–85°F and nights 60–70°F.

Spring planting starts after the last frost and when nights stay above 55°F. Soil should be at least 65°F. Cold soil stalls peppers and makes them sulk.

In cool regions, warm the soil with black plastic or landscape fabric a week or two before planting. That simple trick often means faster growth and an earlier harvest.

Transplant peppers on a calm, warm day. Plant at the same depth as in the pot. Firm the soil and water well.

Spacing matters. Bells and other large sweets like 18–24 inches between plants. Jalapeño, serrano, and many hot peppers do well at 12–18 inches.

Mulch right away. A 2–3 inch layer of straw, shredded leaves, or compost keeps moisture steady and soil warm. It also cuts down weeds.

In spring, protect young plants from chilly nights with a light row cover. Remove it during hot days and when flowers open so pollinators can work.

Now let’s talk fall planting. In many parts of the U.S., you plant peppers in late summer for a fall harvest. You start seeds earlier, grow transplants, then set them out as the worst heat passes.

Count back from your first frost date. Most peppers need 60–90 days after transplant to ripen fruit, longer for habaneros. You want enough time to harvest before frost.

In Zones 8–9, transplant for fall in late July through August. In Zone 7, aim for late July. In Zone 6, you’ll need season extension and an early transplant in mid-July to have a shot.

In Zones 3–5, a fall outdoor pepper crop is tough. You can do it only with a greenhouse or a tunnel. Otherwise, focus on spring and summer.

Fall peppers love the cooler nights and bright days once summer heat eases. You’ll often get thicker-walled bells and great color. Just be ready with frost cloth when nights dip.

For fall, start seeds indoors about 10–12 weeks before your late-summer transplant date.

Give them strong light. Keep growing conditions steady and warm.

I like to stagger starts. I sow a batch for spring, then another batch 6–8 weeks later for a fall transplant. It spreads out the harvest.

Use fresh, sterile seed starting mix. Bury seeds about 1/4 inch deep. Keep mix evenly moist, not soggy.

Bottom heat is your friend for peppers. A seedling heat mat at 80–85°F speeds germination. Remove the mat after most seeds sprout.

Give seedlings 14–16 hours of light each day. Keep lights 2–3 inches above the leaves. A small fan builds stronger stems.

Harden off seedlings for 7–10 days before planting out. Start with shade, then give them more sun and wind each day. Keep them watered while they adjust.

Peppers like well-drained, fertile soil with a pH around 6.2–7.0. Mix in 2–3 inches of compost before planting. Avoid very fresh manure.

At planting, use a balanced, low-to-moderate nitrogen fertilizer. Too much nitrogen makes big leaves and few fruits. A 5-10-10 or similar ratio works well.

Side-dress with compost or a bloom fertilizer when the first flowers set. Add a second side-dress mid-season if plants look tired. Water after feeding.

Water deeply, about 1–1.5 inches per week. Aim for even moisture. Uneven watering leads to blossom end rot and split fruit.

Drip irrigation or a soaker hose is ideal. It keeps leaves dry and lowers disease risk. Mulch helps hold that moisture in.

Stake or cage peppers, especially bell types. A simple stake keeps heavy fruit off the ground. It also reduces stem breakage in wind.

Prune lightly for airflow. Remove leaves that touch the soil. Pinch very early blooms on tiny plants so they focus on roots first.

Watch the weather. Above 90–95°F, flowers may drop. Use a 30% shade cloth in heat waves to save blossoms.

When nights drop below 55°F, growth slows. In fall, be ready to cover plants. A simple frost cloth can buy you two or three more weeks.

Sweet peppers and hot peppers differ in a few key ways. Hot peppers often handle heat and drought a bit better. Sweet peppers need steadier water for thick, sweet walls.

Habanero and other super-hots take longer to mature. Plan 90–120 days after transplant for many of them. Bells and jalapeños are faster, often 65–85 days.

Container size differs too. Big bells like 5+ gallon pots. Many hot peppers do fine in 3–5 gallon pots, though bigger is always better.

Will cross-pollination make bell peppers hot? No, not this season. Crosses only affect the seeds you save, not the flavor of this year’s fruit.

Heat level in hot peppers rises with mature stage and variety. Stress can boost heat but may hurt yield. Aim for healthy plants first; flavor follows.

To grow sweet peppers with the best flavor, keep water steady and give them full sun. For the best heat when you grow hot peppers, let fruits fully mature to their final color.

Back to that seed question. If you’re new, start with sweet bells or jalapeños from seed. Try habanero from transplants your first year.

Pests to watch: aphids, whiteflies, spider mites, thrips, flea beetles, and cutworms. Use row covers early, hand-squish, or spray insecticidal soap or neem when needed.

Diseases to watch: bacterial leaf spot, phytophthora root rot, and mosaic viruses. Rotate crops yearly and avoid planting peppers after tomatoes, potatoes, or eggplant.

Blossom end rot shows as black, sunken spots on the bottom of fruit. It’s mostly from uneven moisture and fast growth. Keep water steady and mulch; calcium in soil must be available.

Sunscald looks like pale, leathery patches on fruit. Leave some leaf cover and use light shade in extreme heat. Pick ripe fruit promptly.

Harvest time depends on your taste. Bells taste sweeter when fully colored red, yellow, or orange. You can also harvest green if you like that flavor.

Jalapeños are great green with corking lines, and also tasty red when fully ripe. Serranos start green and turn red or orange. Habaneros often ripen orange or red.

Cut peppers with pruners and leave a short stem. Don’t yank—stems tear easily. Frequent picking keeps plants producing.

Store peppers in the fridge crisper for a week or two. They prefer slightly warmer storage around 50–55°F, but the fridge is fine short-term. Don’t wash until you use them.

Containers are great for patios and fall flexibility. Use high-quality potting mix, not garden soil. Water more often, because pots dry fast.

Fertilize containers lightly but regularly. A slow-release fertilizer plus a monthly liquid feed works well. Flush pots with clear water once in a while to prevent salt buildup.

In warm regions, you can even overwinter peppers in pots. Cut back lightly, move indoors to a bright, cool spot, and keep soil barely moist. Growth slows, then they bounce back in spring.

Here’s a quick seasonal map in plain words. North and mountains: focus on spring planting after frost; fall crops are tough outdoors. South and coastal: plant in spring and again in late summer for a strong fall harvest.

One more personal tip. My best fall jalapeños came from a late July transplant into warm, mulched soil, with a bit of shade cloth during heat waves. The plants exploded when September cooled.

By now, you know how to grow peppers of all kinds including bell and other sweet peppers as well as serrano, habanero, jalapeno, and other hot peppers. Start strong in spring, count back for fall, and adjust for your zone. Grow sweet peppers for crunch, grow hot peppers for kick, and enjoy every harvest from garden to grill and jar.

To harvest peppers and cook or preserve peppers, try these easy methods. Roast and freeze sweet peppers. Dry or smoke hot peppers, or make quick-pickled rings and homemade hot sauce.

Good morning. It is already time to go to work again. I am having some mushroom coffee but I need breakfast. I also need to mop my sticky kitchen floor. 

We had someone in to clean on Saturday and let me tell you that the floor is now stickier than before. I just don't get it. Also, nobody will dust no matter how much I emphasize it. I have dusted more this weekend after she left than I have in a month. And we are still finding things that were "put away". Everything has been moved but not much was dusted at all. I think I am done with trying to find someone to clean. No one will. I have had it.

Other than that, it was a good night and my tummy is much better this morning than it has been in a week.

I just made biscuits and eggs with salsa and mushrooms. Yum! 

It is now 10:30am. I finally finished mopping up muddy, soapy water on all of the bare floors in the house, changing the water every time I dipped the mop in. Stickiness is gone. 

I am now out in the business working on seed orders. It is Monday and pay day so it is extra busy and after paying a lot of money to have the house cleaned on Saturday, rinsing the floors is something I should not have had to do. My mind is just blown that no one will actually do what I want done--dust and vacuum. I guess I could make a fortune at a housecleaning business just actually cleaning instead of hiding things.

Yes, I was looking all around my kitchen this morning for baggies so I could put away the biscuits that were not eaten. I finally found them, taken out of one cabinet and put across the kitchen in a drawer. I never asked her to go in my cabinets or drawers. Why? Also, she arranged inside my refrigerator including my eggs that I was going to pack to sell. She put them in my personal egg holder. Again why? Dust and vacuum--that is all I wanted done. Never again.
