Fruit size, season and kitchen use determine variety

This growing advice helps you choose. Your variety, growth stage, weather and conditions in your space determine the actual timing.

A good start

Sowing under cover and raising seedlings

Start under cover in warmth · Chillies & sweet peppers

Mid-February–early March for greenhouse growingStart indoors in warmth and reserve enough bright space for raising plants.

Germination and temperature
Germination: around 18–21 °C. After emergence: good light at about 16–18 °C.
After emergence
Give seedlings light immediately after emergence. A dark loft needs suitable grow lights; warmth alone is insufficient. Ventilate and keep the compost moist without saturating it.
Pricking out and potting on
Prick out once the first true leaves are manageable. Hold a seedling by a leaf. Pot on when the roots fill the root ball.
Hardening off and planting out
Gradually acclimatise indoor-raised plants to sun, wind and outdoor temperatures; shelter them again on cold nights. An unheated greenhouse generally from mid-May; outdoors often late May–June, with consistently warm nights (at least around 12 °C). A heated greenhouse can be earlier if temperature is actually maintained.

Sweet pepper needs a long season. Very early sowing without enough light gives no head start. For outdoor growing, a suitable early cultivar may be sown later; follow seed guidance.

How to grow chillies & sweet peppers

The options below belong to the plant. From these, choose the method that suits your variety's growth habit.

Two labelled pots on the patio

A sweet and a hot selection side by side make the difference visible.

  1. Choose two varieties with suitable growing seasons and label each pot clearly.
  2. Use separate, large pots with drainage and acclimatise plants to outdoor light.
  3. Harvest according to variety and use; record flavour, size and picking time.

For a warm, sheltered patio where both plants can receive regular care.

A mixed greenhouse row with soft support

Under glass, sweet and hot varieties can each have their own space.

  1. Make a planting plan with variety names and expected plant size.
  2. Plant at the same depth and support fruit-bearing branches with loose, soft ties.
  3. Ventilate in warmth and check each plant's water requirements separately.

For a hobby greenhouse; one schedule must not hide differences between large sweet peppers and small chillies.

A long, pointed sweet pepper with thin skin

The RHS describes Corno di Toro Rosso with sweet, crisp fruit, thin skin and few seeds, tapering up to 25 centimetres. This helps kitchen choice without promising every fruit reaches that exact length.

Plan for the mature plant

The British profile gives 0.5 to 1 metre height in a sunny, sheltered position. Add support while stem access is easy, allowing later fruit growth without working among laden branches. Leave room to inspect all around.

The young plant does not move in one step

Indoor peppers need wind and direct-sun acclimatisation. Start sheltered and gradually increase outdoor time. The university source links planting to sufficiently warm nights. Apply that principle locally and check forecasts, not dates alone.

Let the growing position set the pace

The Dutch growing source recommends warmth under glass or film for sweet peppers. This also guides the variety without fixing its harvest date. Greenhouses vary in sun and shade; follow flowers and fruit where they actually grow.

Care for the branches bearing the harvest

Pepper branches may break under weight. Inspect hanging fruit and support bearing shoots as needed. Topping is not automatic and can delay fruiting. The profile mentions topping for branching; weigh against remaining time and room.

A steady water supply helps the fruit

Check root-zone moisture and prevent major fluctuations. Poor water supply can cause pepper flower loss and fruit problems. This is general growing knowledge. Consider soil, weather and stage together to adapt care to actual plant needs.

Turning red takes extra time on the plant

This variety ripens green to red. Leave fruit colouring on the plant if you want red. A green, full-sized pepper is another harvest choice, not a failed red fruit. Cut the stalk to avoid damaging its branch by pulling.

Taste the choice you have made

Pointed sweet peppers suit raw and cooked dishes. Taste a piece before using it. Note chosen ripening colour and flavour opinion with the harvest. This helps decide how many plants of the variety to grow next season.
