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.

Rebecca, in a temperate zone you can only expect capsicums to be annuals. Remove the plants as they die down and grow new ones for next summer.

Diane, you will be able grow capsicums if you start them early under cover so that they have a long growing time.

do capsicum plants grow well in big pots? Because I have just planted some seedlings in a big pot, and I am wondering if they will still produce fruit.

You can grow Capsicum in pots quite successfully, keep the soil moist not too wet and feed with nitrogenous fertilizer when fruit are starting to set Tom in Hawkes Bay

how long do capsicums take to grow? because I put some in in september and they were allready seedlings and now their about 20cm tall but they are not flowering, why not???

Lucy, my capsicums have also been slow starting. I think the cool spring nights have slowed them down. You should see some improvement as the weather settles down.
