How do I grow capsicum and chilli in a raised bed?

Plant into warm mix in the sunniest spot. Stake taller varieties so heavy fruit doesn't snap the stems, and pinch the first flower to build a stronger plant.

Water deeply and consistently — uneven watering brings on blossom-end rot. Feed every couple of weeks once fruit sets; a food like Dynamic Lifter suits them.
