  • 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.
  • Chilli harvest
  • 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

Chillies 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!

What does T and S mean is that when I would want to move the indoor seedlings outdoors?

S means sow (suitable time) and T means transfer seedlings to growing bed. You could harden them off a bit by putting them outside (in their little pots or trays) during the daytime and then moving them under cover at night. Do that for about a week, then going out into a garden bed will not be such a temperature shock for them.

Can I bottom water superhot peppers, (reapers, ghosts, scorpions) through grow bags? Will doing this cause my 7 gallon grow bags to rot out? Will the water even reach my plants in a container this size? Thank you for your help!

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 (??)

Last year I had a great crop of Scotch bonnet peppers from a plant that was given to me and I saved some of the seeds. How do I start making seedlings and when do I start planting them for this year?

I live in San Pedro in zone 10b. My vegetables include, tomatoes, snap peas, green beans (not pole), radishes, green onions and cucumbers. Except for tomatoes and jalapeño, serano and pan lamp are grown by seed. I am attempting to grow exotic hot peppers of many varieties. What hot peppers grow well here from store bought plants (very limited ) and seeds? Not interested in bells. Jalapeño, habanero, shishto, ghost, pequins and chiltepins are my main focus. Thanks for any advice and suggestions.

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?
