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

S = Plant undercover in seed trays. P = Plant direct in garden where they are to grow.


  • 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' chilies.
  • Compatible with: Best grown in a separate bed as chillis need plenty of light and air circulation.
  • Small, hot, chilli

Small bushy plants. Dark green ovate leaves.

Chilli need warm frost free weather, so protect with glass or plastic covers if planting outside in cooler areas.

Most varieties need a long growing period to produce many fruit.

There are many types of chilli. Some are more fiery than others. As a general rule, the smaller the pod the hotter the taste.

Culinary hints - cooking and eating Chilli

Chillis freeze very well. Wash, dry, and free whole. Use them direct from the freezer (no need to defrost).
Wear plastic gloves or wash your hands thoroughly after handling and cutting to avoid accidentally rubbing chilli juice onto your mouth or eyes!

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.
