  • 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.

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.

My chilli plant was prolific with aprox 3cm sized fruit for the last few years. Now it has flowered again abundantly but the fruit are maturing tiny (0.5cm) and round. What is it lacking?

Megan, I have had the same problem with growing jalapenos, the plants make a lot of fruit, but they all stay very small and not spicy. I have found some other chili varieties grow better, birdseye chilli's especially. Someone suggested that the pH in my soil might be too high, I havent checked it though.

Julie, chillies will do better in full sun

Do chilli's need full sun to grow or just morning? I am just getting ready to put in a vege patch.

I was just wondering, my chili's are very small and not very hot. Is there a way to encourage them to grow bigger? It's only 10 months old. Thanks

Thank you so very much for the Slater advice. I will try the orange.

Tammi - it might be slaters. Put a piece of orange near the plants at night, and check early the next morning. If it is slaters eating the chili plants, they will congregate on the orange, which you can then dispose of, with the slaters! Repeat until you are slater-free. If you don't have pets or kids, you can also crush up snail pellets to a powder as the slater's mouth parts or too small to eat the big pellets.

A question if anyone can. I live in Mandurah WA, something is eating my chilli seedlings off to a stalk. I have used ant and grub powder and also snail pellets. Any advise? Thanks Tam

Absolutely, the purpose of the grow bag is to weep the moisture from the ground. If you have the bags on a different surface than bare soil/(non-permeable) you're not using them the way they were intended to be used. You could actually use a bathroom scale and weigh the bag filled with soil/ and planting before watering. Get them all around the same weight, remember or record. Totally saturate the bags, wait until all water dissipates from around them/ excess water drains out and weigh them again, record. You will know exactly how much moisture/medium they hold (8lb/1gal). Over the course of the next days/weeks depending on your conditions, if you go so far as to monitor the weight via the scale or just pick them up to see how heavy they feel you will learn when they (??)
