Jan F M A M J J A S O N Dec

Not recommended for growing in New Zealand - cool/mountain regions

  • 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 64°F and 95°F. (Show °C/cm)
  • Space plants: 8 - 20 inches 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.

What is the difference between planting it in trays and sowing it
08 May 23, Anonymous (Australia - sub-tropical climate)
A tray probably means a seedling tray. To sow is straight into the soil.

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.
