(Best months for growing Chilli peppers in New Zealand - cool/mountain regions)

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

September: After risk of frosts

  • 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: 16 - 20 inches apart
  • Harvest in 9-11 weeks. Wear gloves to pick 'hot' chillies.
  • Compatible with (can grow beside): Best grown in a separate bed as chillies need plenty of light and air circulation.

Maybe I am biased but I wouldn't use chemical fertilisers like you mention as they destroy soil life. Healthy soil teeming with soil life is the answer. Build your soil up with old manure, compost and any organic matter and 'numbers' won't be necessary.Use crop rotation starting with a leaf crop after you have added manure, etc to the soil. When the leaf crop is finished plant a fruit crop (beans, capsicum, tomatoes zucchini, etc), then finally a root veg crop. Re-fertilise the soil ready to start the cycle again. plants need more than N-P-K and organic matter will achieve this, building up the soil life, increasing the capacity of the soil to hold water, increasing disease resistance and making more micro-nutrients available to your plants. adding some lime in late autumn or winter will also help. Trust this helps.

Hello, we had the first frost this morning, my plant is full of big green chilies, is it now time to pick all my chilies or will they still turn red? Also how do i save chilie sead for next year?

If the chillies are hit by frost they are likely to rot. I suggest pulling the plants out by the roots and hanging them upside down in a protected spot. This works with tomatoes and at least you would redeem some or most of them. To save seed cut or flick them out and let them dry on some paper towel. Store them in a paper bag or envelope with the name and date on it.

Do I nip top stems off to increase side stems and fruit
02 Feb 17, Karen (New Zealand - sub-tropical climate)
Yes. Not counting the seed leaves I generally let the plant grow to about 8 true leaves then remove the lower 2 (ventilation space under growing plant) and cut the stem leaving 4 true leaves. This results in a stronger stem, more side shoots = more fruit. This works well for me growing one plant per 15L container.

If you nip off the stem they will be sturdier plants and I have found they do produce more fruit.

What kind of fertilizer does chillies need

Growing indoors, they will need an even warmth and plenty of light. If they are on a windowsill, watch that they don't get too cold overnight.

Snails love small chilli plants so when you plant put some snail pallets around. Chilli doesn't grow well in small cup size plastic pots so don't use them or if you buy a chilli plant in one transplant to a large ceramic pot immediately. Grow from seed in a sandy garden bed seems to work very well to germinate, when the plants are as tall as your finger transplant them into a largish ceramic pot 2 litre minimum and don't be scared of leaving them in a large pot as they grow well in pots. Use a reasonable quality potting mix and water every day, mornings best, Full sun is best so find a spot where the chilli gets the maximum sun possible. The potting mix will have enough fertiliser for the next growth stage so don't add any fertiliser for the next month. Then add blood and bone and watch them grow quickly and start to flower. I've had really good results with blood and bone so have not needed to try alternative fertilisers like manure. The beauty of blood and bone is it is almost impossible to burn or kill your plants. Finally add potash fertiliser a month after the blood and bone to ensure the chilli bush has plenty of fruit. The chilli's ive grown in big pots grow jjust as good as the ones in the garden beds if not better. L put that down to the warm soil and potting mix. I live in Perth too so I hope you have luck with your chilli's
