How long do peppers take to grow?

From seed to the first ripe pod, plan on about 20 to 25 weeks for most peppers and 23 to 30 weeks for habanero types. Your seedlings spend 8 to 10 weeks indoors, wait 2 to 3 weeks past the last frost2, then most varieties ripen 70 to 85 days after you plant them out1.

8–25daysfor seedlings to come up at 70–85°F2
70–85daystransplant to first harvest, most types1
90–120daystransplant to ripe, habanero types1

With a last frost on April 20, a jalapeño you sow in mid-February goes out in early May and gives its first pods from mid-July, while a habanero sown the same week can run into early September. Habanero types need three to five more weeks of warm weather than the rest, so they set your sowing date. Once a flower opens, the pod takes another 35 to 45 days to reach full color4.

Should you start from seed or buy transplants?

Buy plants if you want the easy start; sow seed if you want a particular pepper. Utah State says transplants mature about 4 weeks before seeded peppers and suits them to cooler areas, and it notes that garden centers often carry a limited selection, so for a specific variety you grow your own transplants from seed4.

Seed starting takes a heat mat, a light and about ten weeks of attention. The seed-starting hub counts the weeks back from your frost date and shows how warm the mix has to be. If you buy plants, Utah State looks for 6 to 9 mature leaves and a well-developed root system, and pulls off any flowers or fruit before planting, because transplants carrying them establish slowly and yield poorly4.

What does a pepper plant need?

Full sun, warm soil, steady water and room for its roots. Peppers grow best between 65 and 86°F2, stall in cold soil and drop flowers in long hot spells, so most of your work is timing the plant into its comfortable months.

Sources agree on the broad shape and differ a little on the numbers, so the table shows each one's figure.

The soil numbers differ by 5°F. Planting at 60°F is your floor; at 65°F the plants start growing right away instead of waiting1. Your zone number matters less than you might think, since it measures winter cold; the climate hub shows the temperatures that do decide your season.

How do you prepare the bed?

Test your soil first, then add only what the test asks for. Utah State works any fertilizer the soil test calls for into the top 6 inches, and caps compost at 1 inch of well-rotted material per 100 square feet4. Peppers do not tolerate waterlogged soil, so Penn State plants them in well-drained ground or a raised bed2.

Pick the sunniest bed you have, even if it is not your favorite spot. UC IPM keeps vegetables away from the shade of trees, fences and walls, away from lawn sprinklers and away from ground that had disease problems before5.

When and how do you plant peppers out?

Once the soil reads at least 60°F and nights stay above 50°F, about 2 to 3 weeks after your last frost23. The guide to when to plant peppers turns your frost date into the exact week.

  1. 1

    Plant in the early evening

    New Mexico State transplants in the early evening to cut transplant shock, and waters right after.6

  2. 2

    Space them out

    About 18 inches apart in the row, with rows 18 to 24 inches apart.4

  3. 3

    Strip any flowers

    Transplants carrying flowers or fruit establish slowly and yield poorly, so pick them off.4

  4. 4

    Put the cage in now

    Pepper stems turn brittle as the plant grows, so set cages or short trellises at planting.1

Spacing changes with your bed and your summer, and the pepper plant spacing guide sorts the published gaps from 12 to 24 inches1.

How do you feed and water peppers through summer?

Water deep and on a schedule, feed small and on time. Utah State gives 1 to 2 inches of water a week and side-dresses each plant with 1/4 tablespoon of 21-0-0 at 4 and 8 weeks after transplanting4. The care calendar lays every job out by growth stage, and the fertilizer guide covers which bag to buy.

Uneven watering is the costly mistake. Utah State says too much or too little causes flower drop and blossom-end rot4, so a drip line or a soaker hose, which Maryland rates excellent for peppers, is worth setting up1.

Can you grow peppers in pots?

Yes, in a pot of at least 5 gallons with a drainage hole. UMD Extension sets 5 gallons as the minimum1, and UW–Madison Extension adds a depth of 12 to 18 inches and daily watering once plants are big and fruiting7. The hub on growing peppers in pots works out how much mix to buy and which compact varieties to pick.

Why do pepper plants stop setting fruit?

Heat, dry soil and too much nitrogen are the three causes extension services name most. Check your plant against each one before you change anything.

  • Hot nights. Evenings above 75°F slow or stop pod production, UMD says; a spray of water cools plants in hot, dry spells.1
  • Dry or uneven soil. Dry spells cause blossom drop, small fruit and blossom-end rot.1
  • Too much nitrogen. Plants turn bushy and leafy and bear late.3
  • Heat above 100°F. UC IPM says it cuts pollination, fruit set and yield.5

Most stalls clear up when the weather turns. The pepper plant problems hub sorts the rest by what you see on the leaves, flowers and fruit.

When and how do you harvest?

Pick a pepper once it is full size and firm, green or fully colored. Utah State wants pods firm, plump and smooth-skinned, and Maryland cuts them off with snips instead of pulling, so the brittle branches do not break14. The harvest hub gives each pepper's days and ripe color, and whether waiting for red makes it hotter.

Keep picking once your first pods are ready. A plant left unharvested slows its flower and fruit production8, and fresh pods keep 1 to 2 weeks at 50 to 55°F4.

Which peppers should you grow first?

Start with what your season can ripen. Most sweet and hot types finish 70 to 85 days after planting out, while habanero types need 90 to 1201, so in your short summer a jalapeño or a cayenne is the safe first plant. The hot pepper plants hub compares the varieties by species, season and height.

A pepper is a tender perennial grown as an annual, UMD Extension says, so a favorite plant can carry on only if you bring it inside before the first frost1.

What does each stage of the season ask you to do?

Four stages, each with a short list. Find the one your plants are in, do the items, and skip the rest until later.

Before the plants go out

  • Test the soil, and add only what the test asks for.4
  • Wait for soil at 60°F or warmer at planting depth.2
  • Pinch flowers and fruit off the transplants.4

Planting day to first flowers

  • Water 1 to 2 inches a week, deep and not often.4
  • Hold organic mulch until the soil passes 75°F.4
  • Set cages or short trellises now, because the stems turn brittle.1

Bloom to harvest

  • Keep soil moisture even; uneven water drops flowers.6
  • In a hot, dry spell, wet the leaves and give late afternoon shade.8
  • Pick ripe pods so the plant keeps flowering.8

The weeks before your first frost

  • Start pinching new blossoms about 60 days before your first frost, so the plant spends its sugars on pods that can still ripen.9
  • Before a killing frost, pull the whole plant and hang it upside down somewhere warm so the last pods ripen.1
  • Gather mature green and slightly colored pods and keep them at 55°F.4

The fruit-set guide has the full count back from your frost date.

Which pepper problem are you looking at?

Match what you see to the guide that owns it. Each one starts with the cause that comes up most often and shows how to rule out the rest.

If you cannot place your plant in the table, the pests and diseases hub sorts problems by the part of the plant they hit.

How many plants and how much bed does your household need?

Start from Utah State's rule of 3 to 4 plants per person for fresh eating, plus 5 to 10 more if you plan to pickle, can, dry or freeze4. Then give each plant 18 inches in the row and 18 to 24 inches between rows, which is 2.25 to 3 square feet each4.

A 4-by-8 bed is 32 square feet, so it fits a 2 person household that eats peppers fresh, or one person who also preserves a batch. For pots, count one plant per pot and give each pot 5 gallons or more1.

Quick answers

Quick answers

Pip, the Scovidex chili mascot, ready with answers
Can I sow pepper seeds straight into the garden?

You can where the season is long. Utah State Extension gives seeding 4 to 6 seeds half an inch deep about 2 weeks before the last frost, then thinning to one plant, but notes that transplants mature about 4 weeks sooner and suits cooler areas better.4

How often should I water pepper plants?

Aim for 1 to 2 inches a week, given deeply and not often, Utah State Extension says. UMN Extension adds a thorough soak at least once a week when rain falls short of an inch, and more often in sandy soil. Uneven watering can cause flower drop and blossom-end rot.34

Should I pick off the first pepper flowers?

On seedlings still indoors, yes: UMN Extension says to pinch off flower buds until just before you set the plants out. Utah State adds that transplants carrying flowers or fruit establish slowly and yield poorly, so remove them at planting.34

Do I have to wait for peppers to turn red?

No. UMN Extension says many varieties taste good green as well as ripe, jalapeños included. Utah State puts the wait from flower to full color at 35 to 45 days, depending on temperature and variety.34

Are hot peppers harder to grow than sweet ones?

No harder, only slower in the case of habanero types. UMD Extension gives most sweet and hot peppers 70 to 85 days from transplant and habanero types 90 to 120, and says planting sweet types next to hot ones will not make the sweet peppers hot.1

How many pepper plants do I need?

Utah State Extension suggests 3 or 4 plants per person for fresh eating, plus 5 to 10 more if you want to preserve some. UMD Extension expects 2 to 8 pounds of peppers from a 10-foot row.14

Do pepper plants come back every year?

Not outdoors where it freezes. UMD Extension calls the pepper a very tender warm-season perennial grown as an annual, and frost injures its top growth, so a plant only lives on if you bring it in before the first frost.1
