(Best months for planting 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 in same bed): 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. Then 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 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.

Or 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.

This is my second year of growing capsicums, I just pruned it at the end of season last year. Noticed the capsicums this year are more red in colour than the common green last year. But my question is can I prune them again this year ready for next year or will I be wasting my time. I have had a good return although they are not massive in size. Thanks. Deb

Hi, I was just wondering how often you harvest and how many times before you should clear for new crop?

we sowed some capsicum seedlings which were - mixed capsicum - some of them have come on with narrow yellow fruit that look like chili rather than capsicum. we have never seen them before. could you tell us what to do with them and how to cook them please

Frances, I looked up Capsicum, in some places they're called Bell Peppers and there is a variety that looks like chili. Cooking them, alongside potatoes, carrots and other vegies in a roast dish, being thin skinned they do dry out quickly so later in the cooking time is best. Chopped coarse and added to a stew type dish or as I did today as part of a salad. I'm not a culinary whiz but do like cooking.

Hi, I have the same capsicums, what's the best way to tell if they are ripe?

I have capsicum that grow to half their size and go rotten in a patch (25%).AND if the don't go rotten they fall off the bush when only half their size. Am I watering too much (Every Day)..Fruit fly???Bundaberg Qld..

Capsicums need to be watered only at the roots. If watering overhead, they absorb the water into the fruit and rot. NPC fertilizer is a good all round fertilizer for moving them along. Watering in the early morning also helps.

Thanks Jean - I will give it a go.
