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

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

I've had better luck growing them against the southern side of the house. That way the heat from the sun is bouncing back off the building onto the plants. You can also make a little wall around them to help heat them.

What bulbs can I plant indoors in south Florida?

My bell peppers are still producing from summer. Not nearly as much, but they are still holding their own. Based on the chart I should be planting undercover in seed trays. Should I have pulled out these bell pepper plants at the end of summer? Will they continue to produce until the frost hits them???? curious

I would keep them if they are still producing good crop.

Peppers can live for a couple of years; if your plants are still alive through the winter, they should produce the next year. If it snows out, bring them in where it’s cozy as long as they live they will produce I think a maximum of four years depending on the health and care of the plant.

If you start with good friable soil that has had some compost/composted manures in it that should be all that is required.
