S = Plant undercover in seed trays T = Plant out (transplant) seedlings

September: After risk of frosts

  • 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 18°C and 35°C. (Show °F/in)
  • Space plants: 40 - 50 cm apart
  • Harvest in 9-11 weeks. Wear gloves to pick 'hot' chilies.
  • Compatible with (can grow beside): 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 peppers

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!

I bought a chilli plant, very small, and it grew into a lovely plant, heaps and heaps of chilis. My question, will it flower again each year and produce new fruit each year? Or do I throw it away, and plant a new one?

Best to google it and read up. Can be annual or perennial.

Hello, I would like to grow rocoto chilli as I have heard that they grow better here in NZ than other varieties. can you let me know when to sow the seeds and when to transplant into the garden or pots please. I reside in Nelson on the south island. Kind regards Edward

The advice here covers all chillies. Look at the notes here it tells you when to plant. When seedlings are about 75-125mm high transplant.

Just my observations. I am in zone 8a. I built my first lasagne bed in the fall of 2018. Then planted n spring of 2019. I experimented with a variety of chiles. Poblano, Thai, Cayenne longs, Pasillas, Italian sandwich, Sweet Bells, and Jalapeño. The bed got full sun, I planted closely, and harvested 472 mature chiles. Every variety produced heavily. This would seem to contradict your data, that chiles need growing room, and good air circulation. The “ stems” were more like trunks of a two year old fruit tree. Almost 2” in girth and very sturdy. I submit this data not to gloat, but for further consideration. Thank you!

Jim what date did you plant your chiles? I'm new to the area and gardening and want to plant poblano peppers. Thank you

Hey Jim, How many plants did you plant in the bed? One of each? I'm doing a variety of chili peppers in containers this year and your comment gives me hope that two plants could fit in one 7 gallon grow bag. Thanks! Best, Colleen
