How to Grow Californian Wonder Capsicum
Sow seeds into seed trays or small pots using a quality seed raising mix. Capsicum seeds germinate best in warm conditions, so provide consistent warmth and keep the mix evenly moist but not waterlogged.
Transplant seedlings into the garden once they are strong enough to handle, temperatures have warmed and all danger of frost has passed. Choose a sunny, sheltered position with fertile, well-drained soil enriched with compost.
Keep plants evenly watered, especially during flowering and fruit development. Mulch around the base of plants to conserve moisture and reduce weed competition. Staking may be useful when plants are carrying heavy crops.
Harvest fruits green once they reach full size, or leave them on the plant to develop a sweeter flavour and mature red colour.
Harvest
Harvest capsicums when fruits are firm, glossy and full-sized. Pick green for crisp texture and classic capsicum flavour, or allow fruits to ripen fully to red for a sweeter taste. Use scissors or secateurs to cut fruits from the plant to avoid damaging stems.
