(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 18°C and 35°C. (Show °F/in)
  • Space plants: 40 - 50 cm 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.

Hello. Does Chilli go out of season, if so, when?

I have a Chilli Peter bush that I have had a lot of peppers off, can I keep it growing for another season? Thanks Aaron

I have a chocolate Habanero plant which I brought inside to over winter and I'm amazed to say it actually flowered and I see it has fruit developing now (mid August). These chilli plants need a long growing season and I'm optimistic that I'll get masses of fruit from this plant in the coming months for my hot sauce recipes. Did you manage to over winter your chilli plant Aaron?

how long does it take for chilli seeds to start to show in a seed tray. I've put mine in almost two weeks ago and no sign of them yet.

I'm in Ft. Lauderdale Florida (10B). I have the same issue. I've got a plethora of differing varietals that I germinated outdoors in Solo cups beginning in March. Some plants are 6"-8" tall while others are just starting to sprout. My Thai Chili Peppers are growing exceptionally well while the bell peppers are taking there "sweet" time getting here. The struggle is real.

Do you use a plant heat mat. It can be bought online or may be found at garden centers like Lowes or Home Depot. Peppers like heat for good propagation

do chillies continue to ripen once they have been picked? Cheers Paul

Yes, they will ripen slowly in the same way that capsicums do. Probably need to be starting to change colour.

I don't mean to be rude, but would like to clarify a few things that have been said here, and give a bit of information. The Bhut Jolokia is supposed to be ~1.5 million Scoville units in heat and is realistically about 1 million, compared to a Habanero, which is usually ~300,000 Scoville units. The habanero is too hot for most, and the Bhut Jolokia is only for the diehard Chilliheads. Scotch Bonnets, Habaneros, and Bhut Jolokias are all Capsicum Chinense, whereas the standard chillies (pointy-ended ones) are Capsicum Annuum, and are usually alot more mild. Sweet Bell Peppers (Capsicums) are C. Annuum, and can cross-pollinate with other Chillies. Kate - Chillies are usually fairly slow-growing plants compared to things like Tomatoes etc. Right now, it may be too cold for them to be in full swing. The flowers are self-fertile, so will pollinate themselves, but you need to help them along by sticking pollen to the Pistil using a cotton bud or similar. Swirling your finger around gently inside the flower works too. When the fruit is pollinated, the flower will go brown, and drop off, and the fruit should start growing. Flowers browning and dropping could also be due to a poor feeding regime. On most (all?) fertiliser bottles you will see a NPK number set. N=Nitrogen, P=Potassium, K=Phosphorus. General vegetative growth (leaves/stems) is encouraged by high-N analysis fertilisers, and flowering is encouraged by high P/K analysis fertilisers. At this time of year, I have my chillies inside on shelves in front of a large west-facing window. Usually, I find that if the overnight low temperature drops below about 5 degrees C then they will stop growing/flowering. I would try and be patient with your Capsicums and Chillies. As they are already established, you should get a good head start this season. Good luck!
