Bell pepper care guide

Capsicum annuum

Also known as: Sweet pepper, Shishito pepper, Chili pepper

Pets and children

Caution advised

The leaves and stems carry nightshade compounds that can upset a dog's or cat's stomach, and hot varieties' fruit burns the mouth, so keep the plant out of reach and see a veterinarian (or a doctor, for a child) if it is eaten.

How often to water Bell pepper

Spring–Summer (Mar–Sep)
Every 2 days
Water thoroughly once the topsoil dries, as a guide; fruiting plants drink a lot, so check every morning in midsummer.
Autumn (Oct–Nov)
Every 3 days
Harvest continues into about October; the soil dries more slowly, so water about a day after the topsoil dries.
Winter (Dec–Feb)
Every 5 days
Generally out of season outdoors; a plant kept indoors gets a sparing watering about two to three days after the soil dries.

Light and placement for Bell pepper

A sunny, airy spot is about right; stake the brittle branches, and if the fruit bleaches in strong midsummer sun, light shade generally helps.

Overwintering Bell pepper

Overwintering guide: 10°C (50°F) or above

It is generally grown as an annual and finished before the first frost; being a perennial by nature, it can sometimes be kept over at a bright window above about 10°C with sparing water.

Fertilizing and repotting Bell pepper

Fertilizer

A heavy feeder: from two to three weeks after planting, slow-release fertilizer about monthly or liquid feed every two weeks is the usual guide; when it runs short the flowers drop and the fruit stays small.

When to repot

Spring–Summer (Mar–Sep)

Common problems with Bell pepper

  • When fertilizer runs out, the flowers keep dropping and no fruit sets.
  • Letting the first fruit grow large exhausts the plant and cuts later yields.
  • Drought or a nutrient shortage rots the tip of the fruit black.

Tips for growing Bell pepper

  • Picking the first fruit while still small lets the plant build strength.
  • Remove the side shoots below the first flower and train three main branches for good airflow.
  • Harvesting the fruit young and often keeps the plant producing into autumn.

These are AI-generated general guidelines. They vary with the variety, the placement and the pot size. For effects on pets or children, consult a veterinarian or a doctor.
