Give Chilli pepper a warm, sheltered, sunny spot, and cover initially with fleece or cloches. Support tall or top-heavy plants by tying loosely to a bamboo cane. For a bumper crop, water regularly, especially in hot weather, and feed every two weeks with a general purpose liquid fertiliser. Picking regularly, using a sharp knife or secateurs, encourages plants to produce more fruit. Leaving chillies to ripen fully (usually to red) will suppress further fruit production. But that can’t be avoided if you want the richest colour and flavour, and the best fruits for drying.
