It will grow in the ground but most likely die in frost. You can plant in the ground then pot up in around the end of April. Keep it out of frost. Then in mid August to September you can plant in your garden again after the last expected frost. If you have a north facing window with good sunlight you can leave it in the pot for now then bring it inside for winter next to the window. I would now save the ground planting until next spring. The height depends on species/variety. Almost all chillies will grow bigger in the ground though.

Stop watering them daily. Once a week is ok, every 2-3 days in summer.

I planted about 10 chili plants of different varieties in October. Only 1 variety has produced chilies. The other bushes are big and green and have been full of flowers for about a month, but no chilies. They are all in the same section of the garden. Do you have any thoughts on how I can get them to produce? Thanks.

Chillis love nutrients! Give them a dose of liquid fertilizer ( I use Go-Go Juice or Charlie Carp) both available from Bunnings/Masters. Once they do fruit....the more you pick, the more chillis will fruit! If you have flowers you will get chillis....just give them time and lots of water in the hot season.

First time gardener here! I planted young 15cm jalapeno plants almost two months ago. There were four stems all together in a small rectangular pot, so I planted them as they were. I assumed the instructions meant space them apart from other plants at x distance, but was I supposed to separate each stem and plant them apart? They're just budding little fruits now but I'm worried they'll fail eventually. Any advice?

Hi Stuart, Ideally it should have been separated at the time when they were young,This would have given each punnet to grow and you could have enjoyed more fruits but don't worry if pot size is good they could be grown together.The best pot size for chill from my experience is 40 cms.You can always re pot and separate them during autumn,

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.
