Mulch sweet peppers during the summer months to keep the soil temperature down as they have quite shallow roots. Keep the compost moist, but not wet. Fertilise weekly – when flowers appear feed with a high potash tomato feed.
Allow to completely ripen before harvesting for flavour.
Peppers, like tomatoes, will not germinate with frost or cold temperatures. For most climates, starting early indoors is necessary. Pepper seeds germinate best with bottom heat keeping the soil temperature around 77-80 ºF (25-27 ºC). There are special seedling heat mats that raise the soil temp 10º above room temp, or you can use a lamp from above to warm the soil. If you do a search you can also find instructions for do-it-yourself bottom heat trays using Christmas tree lights.Ensure a distance of 0.98 inches (2.5 cm) between seeds when sowing - look to sow at a depth of approximately 0.25 inches (0.64 cm). Soil temperature should be kept higher than 20°C / 68°F to ensure good germination.
By our calculations*, you should look at sowing Sweet pepper about 60 days before your last frost date .
Transplant outdoors when seedlings have 5-6 leaves and after soil temp exceeds 55F.Ensure that temperatures are mild (minimum night temperatures should be around 15°C / 59°F) and all chance of frost has passed before planting out, as Sweet pepper is a tender plant.
By our calculations*, you should look at planting out Sweet pepper about 14 days after your last frost date.
Carefully cut off short piece of stem with fruit to avoid damaging plant.
