When to Plant Cayenne Pepper in Oregon

Growing Cayenne Pepper in Oregon: Complete Guide

Cayenne Pepper (Capsicum annuum) is a warm-season crop that needs a head start indoors before Oregon's last frost. Depending on your zone, Oregon gardeners start seeds indoors between December 2, 2026 (Zone 9b) and February 14, 2027 (Zone 5b), then move transplants outside once their zone's last frost has passed — the zone table above has your exact dates.

Because Oregon stretches across 9 USDA hardiness zones (5b, 6a, 6b, 7a, 7b, 8a, 8b, 9a, 9b), planting windows can shift by as much as six to eight weeks from one end of the state to the other. Gardeners in the warmer southern zones can start earlier, while those in cooler northern zones should wait until the zone table above shows their last frost has passed.

With 75 days to maturity, Cayenne Pepper needs the indoor head start that Oregon's growing season requires. Starting indoors ensures you have strong transplants ready the moment outdoor conditions are right.

Cayenne Pepper requires full sun (6-8 hours) and moderate moisture. The Pacific Northwest's cool, wet springs delay soil warm-up; raised beds and black plastic mulch help jump-start the season.
