Sun requirement for cayenne pepper: Plant in Full Sun

Cayenne peppers are a cultivar of Capsicum annuum. They are members of the nightshade family, Solanaceae, and related to tomatoes and eggplant. The upright plants produce long, thin, red fruit that can be up to 25cm long. Cayenne peppers have a Scoville rating of 30,000 to 50,000 units and are slightly hotter than jalapenos. They are generally dried and ground to make cayenne spice, but they can also be used whole or in a thin, vinegar-based sauce.

What are growing degree days?

A plant grows with warmth, not with days. A growing degree day is one day's worth of useful warmth: how many degrees the day's average temperature is above the lowest temperature the crop grows at. Add them up from planting and you know how far along the crop is, whatever the calendar says.

Say that lowest temperature is 10°C. A day averaging 17°C gives 7 growing degree days. A day averaging 8°C gives none, as it is too cold for the crop to grow. That is why the same lettuce takes about 50 days in a summer and 90 in an autumn: it needs the same total warmth either way.

For cayenne pepper, the FAO EcoCrop database gives a lowest growing temperature of 7°C and a shortest growing cycle of 120 days at its best temperature, about 2040 growing degree days to a first harvest.

Where you've told us where your garden is, we use this and the weather there to predict when your cayenne pepper will be ready to harvest. We don't use it for how long a plant lives or when it finishes: we go by what members have logged for that.

Growing cayenne peppers

  1. Sow seeds indoors somewhere warm 10 weeks before planting out
  2. Pot on the seedlings 6 weeks before planting out
  3. Harden off the seedlings 1 week before planting out
  4. Set or refill beer traps for slugs and snails at planting out every week
  5. Stake the plants 2 weeks after planting out
  6. Water regularly at planting out every week
  7. Check for aphids 2 weeks after planting out every 2 weeks
  8. Feed with tomato fertiliser 6 weeks after planting out every 2 weeks
  9. Pick chillies regularly at first harvest every week
  10. Bring pots in before the first frost 3 months after first harvest
