I recently purchased a chilly tree, currently about 40cms tall, will it grow if planted into the ground? We live in Central Gippsland. How tall will it grow?

Compare it to its relative, tomato bush. Depends on the type of chilli. You will have lots of fruit probably and my wife reports they seem to even get hotter when left in the freezer.

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,

Hi. I have my own chilli breeding program going on, and am planning to use a combination of Thai chilli, birdseye chilli, Chilli Diablo, some stock chilli (generic, little spice, huge fruit, and Habanero. All these plants are growing in a full-sun position in neutral soil with some compost and old manure mixed in, making it slightly more acidic, but they seem to love it. I have noticed growth of up to an inch a week if Worm Castings and seasol are mixed with some water and sprayed onto the leaves of the stock chilli and diablo. As the leaves of these two are very large, foliar feeding goes down a treat. The birdseye and thai chillies have smaller leaves, so I just add it into the irrigation water, with equal results. The habanero I have left alone, as a bit of an experiment to see how maintenance-free this part of the veg garden is. All the plants (apart from the diablo) were started from seed in the middle of winter, indoors, and the Thai chilli and Birdseye chillies have been topped as half the crop from them will go into our special family chilli sauce. All plants have abundant flowers, some of which are ready to open, and average about 60cm tall. I hope this helps and inspires some peopleto get into chillies.
