Pepper Growing Basics

When should I plant peppers?

Peppers need warm soil and warm nights. Plant transplants only after your last spring frost date has passed and the soil has warmed. Ask your extension office for your local average last frost date and soil temperature guidance.

Cold snaps stunt peppers for weeks. If you get cold nights after planting, cover plants. Seeds started indoors usually need many weeks before transplanting, so count back from your planting date to know when to sow.

Seed starting is an extra chore for peppers because they are slow, so many first-time growers buy transplants. If you do start seed, use clean containers and fresh seed-starting mix, provide bright light and steady warmth, and keep the mix lightly moist rather than soggy.

Should I grow from seed or buy transplants?

Seed gives more variety choices and costs less per plant, but it needs bright light and steady warmth indoors. Transplants are easier for a first garden and let you skip the early stage.

Choose stocky, dark green plants without flowers or fruit yet, and avoid leggy or yellow plants. Harden off any plant by exposing it to outdoor conditions gradually over several days before planting.

Heat matters in both directions. Very hot spells can drop pepper blossoms even in well-watered plants, so a bit of light shade cloth during a heat wave can help, and fruit often sets again once temperatures ease.

• Stocky stems and healthy leaves
• No visible spots or insects
• Roots not circling heavily
• Variety label that matches your goal

Where and how far apart do I plant them?

Give peppers full sun and well-drained soil. Spacing varies by variety, so follow the tag or the extension publication for the type you grow. Crowding reduces airflow and raises disease risk.

Do not plant where tomatoes, potatoes or eggplant grew recently, since they share diseases. A soil test before planting helps you avoid excess nitrogen, which gives leafy plants and few peppers.

Check your soil drainage before you plant. Peppers sit poorly in soggy ground, and raised beds or mounded rows help in heavy clay. Watch for areas that stay wet after rain and avoid planting there.

How much water and feeding do peppers need?

Peppers like steady moisture. Drought stress and uneven watering can cause flowers to drop and fruit to be misshapen or develop blossom end rot. Mulch to hold moisture and moderate soil temperature.

Feed based on your soil test and the label. Heavy early nitrogen can reduce fruiting, so many growers wait until the first fruit sets before side-dressing, if the test suggests it.

Plant tags usually list days to maturity, which counts from transplanting. Compare that number with the weeks between your planting date and the first expected fall frost, and choose varieties that fit with time to spare. Cover plants before the first frost to extend the harvest a little.

Do peppers need support?

Plants loaded with fruit can snap in wind or under their own weight. A short stake or cage set at planting time keeps them upright without damaging roots later. Tie loosely and add ties as the plant grows.

Branches are brittle, so handle gently during weeding and harvest.

Peppers can stay in the garden until frost threatens, and plants that stop in midsummer heat often resume. Be patient with them before deciding a plant has failed.

How do I know when to harvest, and what about hot peppers?

Many peppers can be picked green or left to ripen to red, yellow or orange, which usually takes longer. Cut fruit with a knife or pruners rather than pulling. Regular picking encourages more fruit.

Hot peppers contain compounds that irritate skin and eyes. Wear gloves when handling them and wash hands before touching your face. Keep them away from children and pets.

Sweet and hot types can cross-pollinate, which affects seed you save but not the fruit you eat that season. If you save seed, keep varieties separated and ask your extension office for advice on seed saving.

What problems should I watch for?

Common problems include blossom end rot, sunscald, leaf spots, aphids and flower drop in extreme heat. Many resolve with steady care. Pick off and discard diseased leaves and check under foliage weekly.

If you are not sure what you are seeing, ask your extension office. Rotate crops each year, and clear debris after harvest so problems do not carry over.

Pick off the first few flowers on very young transplants if they bloom early. This lets the plant build roots and leaves first, and often leads to a stronger harvest later.
