Start seeds out in a greenhouse or on a sunny windowsill, prick out into larger pots when the plants reach 5cm.  Capsicums are heat lovers so wait until November/December when plants are 10-15cm  harden plants off and plant out in position with fertile soil and full sun.

Keep gardens weed free and mulch to keep soil moist.  Taller varieties may require staking.

Colours and flavours change as the capsicum mature, however a capsicum can be harvested at any stage.  A ripe capsicum should feel solid but sound hollow when tapped.

Harvest by cutting – never pulling, pulling could damage both the fruit and the plant.

Storing harvested Capsicum:  Keep in fridge for up to one month. but bring to room temperature before using – this warms the sugars and sweetens the flavour

Seed Saving:   Self pollinating though insects will pollinate.  Isolation distance between varieties of 30m.  10 plants are required for genetic diversity.

Seed Life:  Four years
