  • 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.

I'm actually in Thailand but your site doesn't list that. Having a hard time growing chilies here and looking for any hints. Soil has plenty of nutrients but does not dry out due to the rains and clay underlayer. At this point I'm thinking of adding sand to the soil to aid in drainage. I've dug a hole in the garden down to the clay layer and filled it with water. It drained within 5 minutes so it's really about my topsoil quality. Thanks!

Sand would be too heavy. You need to add compost or other organic matter into the soil when planting. To loosen soilup. Chilies/peppers do better in soil pH 6.5 to 7.0. Helpful info link https://bonnieplants.com/how-to-grow/growing-peppers/

I've planted chillies that keep flowering but no fruit, do you have an idea of what I'm doing wrong. They are healthy!

Need to shake the pollen out of the flowers. Probably not many bees around

Try a little potash around the plants when flowering. Watered in, this should help promote fruiting.

I've planted a row of chillo's all bar one are small bushes producing limited fruit but my healthyist plant is a good size but just keeps flowering with no fruit at all. Any ideas what's wrong.

I use tomato fertilizer and it works well for me.I grow chilli in pots inagreen house.

What fertilizer are people using in New Zealand? I see a lot of sites recommending a 10-10-10 or a 5-10-5, most of NZ fertilizer seem to be high nitrogen.

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.
