(Best months for growing Chilli peppers in USA - Zone 5a regions)

  • S = Plant undercover in seed trays
  • T = Plant out (transplant) seedlings
  • P = Sow seed
  • 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.
  • Compatible with (can grow beside): Best grown in a separate bed as chillies need plenty of light and air circulation.

After picking up some seeds at the garden show, I have added chilli to my seed trays in order to liven up the dinner plate this summer! Unfortunately, the chilli seeds are not striking. I must be doing things half right, as my lettuce, spinach, etc, are all shooting well. I have noticed my chilli packets are all Italian in variety..... Why wont they strike? What am I doing wrong?

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.

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.

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.
