Even in the south-east, it's too cold to start chillies off outside. By mid-May it should be warm enough to put the plants outside, in a sheltered, sunny spot. If you're growing tropical varieties, or if you are in northern Britain, keep plants in a greenhouse or on a warm sill.
Keeping this in view, are chilli plants perennials?
All chillies are edible, even Purple Explosion, which is normally grown as an ornamental variety. Chillies grow in a range of areas. They are short lived perennials in subtropical and tropical areas, but are normally grown as annuals in colder regions because the cold weather causes them to die off.
How do you overwinter pepper plants?
To finish your pepper winter care, about a month before your last frost date, bring your pepper plant out of the cool location and move it to a brighter, warmer location. You may even want to use a heating pad under the pot to add additional heat. Resume watering, but make sure not to over water the pepper plant.
How long does it take to grow a chilli?
We mainly sow seeds during February and March, but you can leave it later. There is a great variance in the number of days taken for a particular variety to reach maturity. Some can produce ripe fruit in 60 days from sowing and others take as long as 120 days.
