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.

Thanks! I had same question.

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.

Could be a number of reasons ... A common ailment with capsicum is blossom-end rot. This condition just effects the fruit and not the plant blossom or flower. The condition gets its name because the symptoms appear at the ‘blossom end’ of the fruit. The first sign of blossom-end rot is that the end of the fruit becomes off-whitish to brown in colour and takes on a ‘sunken in’ appearance. As the fruit matures, these symptoms become more pronounced and the colour of the rot becomes dark brown to almost black. Blossom-end rot is caused by insufficient calcium supply. However, the most common cause is from irregular watering during the critical growing period of the young fruit. Even when calcium levels in the soil are sufficient, a plant receiving insufficient or irregular water will have difficulty absorbing and delivering calcium to the fruit. To control blossom-end rot. Boost the soil with calcium by adding lime, dolomite, gypsum or composted animal manures before planting the seedlings. Water regularly. Most capsicum crops continue to flower and bear fruit for prolonged periods of time, so ensure the soil around their roots is kept moist. Avoid fertilisers with a high nitrogen content. Nitrogen fertilisers will promote leaf growth at the expense of fruit, allocating calcium to the leaves instead of to the fruit.
