When to Plant Chives in Oregon

Growing Chives in Oregon: Complete Guide

Chives (Allium schoenoprasum) is a warm-season crop that needs a head start indoors before Oregon's last frost. Most Oregon gardeners begin seeds indoors around Sunday, January 18, 2026 and move transplants outside around Sunday, March 1, 2026, after the risk of frost has passed.

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 60 days to maturity, Chives 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.

Chives requires full sun to partial shade and regular moisture. Most of Oregon receives adequate sunlight during the growing season, though gardeners in humid eastern regions should watch for fungal issues and ensure good air circulation.
