  • 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.

It says plant seeds in Sept. Probably for soil temperature reasons. You could start inside in August but would have to provide warmth for them to germinate. Put them outside as soon as they germinate otherwise the might grow leggy, very tall and thin, looking for sunlight.

I've sown my chilli seeds in may.. & they are now 30mm high I'm in the garden route where we have mild winters & sun .. do I plant them out or not risk the labour. I want to pot them for summer sales.

Why did you plant in MAY, read when to plant them.

I bought a chilli plant, very small, and it grew into a lovely plant, heaps and heaps of chilis. My question, will it flower again each year and produce new fruit each year? Or do I throw it away, and plant a new one?

I try to take my chillie plants through the winter by protecting from frost and the ones that survive do really well, better than new plants, so I would try to keepit going

i have a jelopeno plant that is 5 years old (in a large pot ) It still produces chillies ..loads of them Its a small tree if you google it. produces mostly smaller fruit but . it does yield a few large ones ( probably more then a younger plant will ) pruning it back, sometimes pulling off the new buds, will transfer the energy back into the plant. of course using the right fertilizer, minerals and Nutrients will also help the plant survive overwintering looks like its dead. But it is survivable if done right

Best to google it and read up. Can be annual or perennial.

Hello, I would like to grow rocoto chilli as I have heard that they grow better here in NZ than other varieties. can you let me know when to sow the seeds and when to transplant into the garden or pots please. I reside in Nelson on the south island. Kind regards Edward

Rocoto chillies Originate from the cool mountain ranges of Peru. Unlike most other chili which like 12 hour`s sun ( beware of sun scold ), Rocoto is quite the opposite .. does better inpartly shaded areas. The fruit stays green like forever, almost 4- 6 weeks.. i think they taste better and sweeter while green .. Way too hot for me when red . Best to do your own research..but definitely shade them out in summer

Tammi - could be mice or rats, they can do this also. Its happened to me in Perth. Megan - Chillies will only grow vigourously during the warmer months, depending on where you are, they will either slow down, go dormant, or die altogether, depening on how cold it gets, a severe frowst will kill them. Wait until summer, they will flower all over, and give you lots of fruit. If you want a hotter chilli, water them less, let them dry out a little (but not all the way). A stressed plant will give hotter fruit. If you want hotter fruit still, get a different variety. Look for a chinense variety. Gareth - Most people raise chillies in punnets/starter pots, then into medium pots (10-15 cm across at the top), then onto final larger pots or garden beds when they have outgrown the medium one. You can tell when they are ready to be moved as they will have roots coming out the bottom. Julie - feed them with tomato food, probably in liquid form, is pretty good for flowering chillies, also, mulch and compost the soil if you can. Murray - depending on the variety, chillies can take up to 6 weeks to germinate, and they also need warm humid conditions to do so. Chillies are originally grown in warmer humid places, so they better you can recreate this, the happier they are. Keep them moist, (but not wet or soggy), perhaps put half a coke bottle over them to keep the humidity up, put them somewhere warm, they dont need sunlight to germinate, so the top of the fridge will do. When they do germinate, move them to a sunny windowsill or similar until they are ready to be hardened off to go outside. Michael - an NPK ratio of 10-5-10 for when they are growing works well, then 5-10-10 for flowering, if using bought fertilizers. Otherwise, a well composted mix of garden waste should work well, with some animal manure thrown in. Dont forget to mulch the soil to stop evaporation.
