Counted from planting out. Variety, plant age, weather, and care can change this estimate.

Pick when the pods reach the mature size for the variety. Use them green, or wait for their final color and fuller flavor.

A long, warm season. Frost injures the plant, cool weather slows it and very hot days or nights can make flowers drop.

First, gather a few things

  • A young chili pepper plant
  • A pot of at least 5 gallons, with drainage holes
  • Potting mix that drains well
  • A watering can or hose
  • A small cage or short trellis can protect tall, brittle stems carrying fruit.

Start or plant it

Follow the steps for the way you chose to start.

  1. Start here

    1. Wait for warm soil

    Transplant after frost danger, when soil is about 65F and nights stay above 50F.

Water

Check the soil first. Heat, rain, and pots can change how often this plant needs water.

  1. 1. Check before you water

    Push a finger about 1 inch into the soil. Water when it feels dry there.

  2. 2. Water the roots

    Water slowly at the base until the soil feels moist a few inches down. For a pot, water until a little runs out of the drainage holes.

    Keep moisture even. When rain is short, soak the root zone at least weekly and check containers more often.

If the plant looks unhappy

  • Too dry

    Flowers can fall, fruit may stay small and leaves can wilt during the hottest part of the day.

    If the soil is dry, water deeply and check it again tomorrow.

  • Too wet

    Soil that stays wet can slow roots and leave the plant weak.

    If the soil is wet, wait before watering again and check that excess water can drain away.

While it grows

Check on your plant and do these jobs as they come up.

Looking after it

  • FeedingAn occasional feed helpsUse a soil test first. If feeding is needed, a light side dressing after the first fruit sets is safer than heavy early nitrogen.
  • NitrogenToo much nitrogen gives leaves instead of food
  • SupportA cageA small cage or short trellis can protect tall, brittle stems carrying fruit.
  • MulchMulch after the soil warms to hold moisture and slow weeds.

Pick and store it

Use the plant's signs of readiness, then harvest gently.

  1. 1. Check if it is ready

    Pick when the pods reach the mature size for the variety. Use them green, or wait for their final color and fuller flavor.

  2. 2. Pick it

    Wear gloves and clip the stem with clean shears. Do not pull on the brittle branch.

  3. 3. Keep it fresh

    Keep unwashed peppers in the refrigerator for about a week. Long cold storage can pit the skin. Freeze or dry extra peppers using a tested food-preservation method.

  1. 1. Clip mature pods

    Wear gloves, cut the stem and keep your hands away from your eyes and face.

Common problems

    Common mistakes

    • Planting out during cool nights

      Cold slows peppers badly. Wait until nights stay above about 50F.

    • Feeding too much nitrogen

      Heavy feeding makes leaves at the cost of later fruit.

    • Handling hot pods barehanded

      Hot pepper oils can burn skin and eyes. Wear gloves and wash tools and hands well.

    Companion plants for chili peppers

    Some of this is measured in trials and some is long-standing garden practice. Each note below says which it is.

    Good together

    Trials show a real benefit:

    • Pollinator flowers (cosmos, borage, basil)In a Texas A&M field study, flowers that attract pollinators, planted with habanero peppers, raised pepper yields.Measured in trials

    Keep apart

    Extension programs advise keeping these apart:

    • Black walnut treePeppers are sensitive to juglone from black walnut roots, so keep pepper beds out of walnut root zones.Recommended by extension programs
    • Sweet cornCorn earworm moths leave corn as the silks turn brown and lay eggs on nearby peppers.Recommended by extension programs

    What soil is best for chili peppers?

    • Soil pH6.5 to 7.0A cheap test kit from a garden centre will tell you yours.
    • Soil it likesLoam, Sandy
    • DrainageWants well drained ground
    • RichnessAverage ground is fine

    Use fertile, well-drained soil. Compost can improve an ordinary bed before planting.

    Test the soil before adding fertilizer. Too much nitrogen delays fruit while leaves keep growing.

    Before changing your soil, learn how to test soil acidity and understand the result.

    When and how deep do I plant chili peppers?

    When to plant

    Match these relative steps to your local seasons. Where frost applies, use the last freezing night in spring and the first in fall. In frost-free climates, follow trusted local seasonal guidance.

    • Start indoors 8 to 10 weeks before your last spring frostStart most types eight to ten weeks before your last spring frost. Some very slow hot varieties need longer.
    • Plant out 2 to 4 weeks after your last spring frostPlant outside after frost danger passes, the soil reaches about 65F and nights stay above 50F.
    • Ready to pick about 70 to 120 days from planting out.

    What happens to chili peppers through the year?

    Measured from your last spring frost, because seasons differ from garden to garden. In frost-free climates, use trusted local seasonal guidance alongside these relative steps.

    1. Start seeds indoors

      8 to 10 weeks before your last spring frost

    2. Plant out

      2 to 4 weeks after your last spring frost

    How do I give chili peppers a better start?

    Simple ways to help your chili pepper grow, from the soil up.

    • Start with good soil

      Use fertile, well-drained soil. Compost can improve an ordinary bed before planting.

    • Give the soil a cover

      Mulch after the soil warms to hold moisture and slow weeds.

    • Support the branches

      A small cage or short trellis can protect tall, brittle stems carrying fruit.

    • Feed with care

      Use a soil test first. If feeding is needed, a light side dressing after the first fruit sets is safer than heavy early nitrogen.

    Test the soil before adding fertilizer. Too much nitrogen delays fruit while leaves keep growing.

    When are chili peppers ready?

    Pick at the mature size listed for the variety. Green pods are usable, while fully colored pods usually have a fuller flavor.

    Can chili peppers grow in a pot?

    Yes. Use one plant in a draining pot of at least five gallons and check its moisture often.

    Why did the flowers fall off?

    Cold, extreme heat and uneven water can all cause flower drop. Keep the roots evenly moist and let the plant recover when the weather settles.

    How should I handle very hot peppers?

    Wear gloves. Wash your hands before touching your eyes, face or bathroom areas, and wash the knife and board after use.
