(Best months for growing Capsicum in Australia - temperate regions)

  • S = Plant undercover in seed trays
  • T = Plant out (transplant) seedlings

August: Sow in pots

  • Grow in seed trays, and plant out in 4-6 weeks. Sow seed at a depth approximately three times the diameter of the seed. Best planted at soil temperatures between 18°C and 35°C. (Show °F/in)
  • Space plants: 20 - 50 cm apart
  • Harvest in 10-12 weeks. Cut fruit off with sharp knife.
  • Compatible with (can grow beside): Egg plant (Aubergine), Nasturtiums, Basil, Parsley, Amaranth
  • 'Banana' capsicum
  • A yellow capsicum

Small bushy plant about 40cm high. The seeds are reluctant to start germinating if temperatures drop at night. These are best sown in small trays in a warm, sheltered place: a small greenhouse if possible. Plant out when about 10 -12cm (4-5in) tall.

They are from the same family as chilli but are not hot and spicy. The seeds and white flesh are bitter.

Capsicums are frost tender and need warmth to ripen the fruit to the brilliant reds and yellows of commercial ones. They can be used green but are not as sweet.

There are a number of colours available, chocolate, black, yellow, orange as well as red. They all start off green and change as they ripen.

In cool, wet weather cover with a cloche or frost fleece.

Culinary hints - cooking and eating Capsicum

Can be sliced and seeded and used raw in salads.
Will freeze successfully without blanching if seeded and sliced.

Brush with olive oil, roast at a high temperature until the skin changes colour then put in a covered dish until cool and rub off the skin and remove seeds.

Can capsicum, eggplant, etc. be grown from seedlings transplanted into (large-ish) pots? Best soil? Will Potting mix be suitable? I am about 50 k NNW of Brisbane as the crow flies. Many thanks.

The bigger the pot the better. Mix some compost or good rich soil into the potting mix. Water regularly and you probably have to fertilise each couple of weeks. Also stake them.

How to bag capsicums to prevent fruit fly infestation. eg individual bagging or by the branch,

I know this is old but answering for future reference. Being stripped of all leaves is usually locusts. Pesticides won't help but encouraging local bird life does. Sparrows of all birds feed on their young voraciously and if you have sparrows you won't have locusts for long. Butcher birds like the adults.

Do green capsicums turn red.or are they different varieties
25 Feb 22, Liz (New Zealand - sub-tropical climate)
Yes, your capsicums will change colour as they ripen. Varieties are red, yellow, orange when ripe.

First time question, new to planting and growing home grown vegetables. But have noticed my capsicum plants have black spots

First time growing mini yellow capsicum. There are heaps on the Bush mainly green going to orange. When do I pick them
25 Jan 21, (Australia - temperate climate)
You can pick, green, orange or wait until yellow.

Sweet baby capsicums, can they be grown in pots? If so, what would be the most suitable size pot considering they grow to 40 cm tall. I thank you in anticipation. Elliot.

Ive had capsicums and chillies over winter and they usually come good once it warms up. I prune them back and when it gets warmer you should find new leaves starting to emerge. Give it a good feed. The old leaves will eventually drop off. I had a chilli plant live for several years in a pot.
