Pepper in a Zone 10 season
Zone 10 gives about 318 frost-free days. Pepper needs roughly 70 days from transplant. That leaves about 248 days of slack, so there is room for a late start or a second planting.
How to grow peppers
Peppers love warmth but sulk in extreme heat. Start seeds indoors about 10 weeks before planting out, and wait until the soil is warm and nights stay mild before you transplant. Where summers are fierce, favor the milder months so the fruit sets.
