When to Plant Ginger in Washington

Growing Ginger in Washington: Complete Guide

Ginger (Zingiber officinale) is a warm-season crop that needs a head start indoors before Washington's last frost. Most Washington gardeners begin seeds indoors around Friday, December 12, 2025 and move transplants outside around Friday, March 20, 2026, after the risk of frost has passed.

Because Washington 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 270 days to maturity, Ginger needs the indoor head start that Washington's growing season requires. Starting indoors ensures you have strong transplants ready the moment outdoor conditions are right.

Ginger requires partial shade (3-5 hours) and moderate-high (consistent moisture) moisture. Most of Washington receives adequate sunlight during the growing season, though gardeners in humid eastern regions should watch for fungal issues and ensure good air circulation.
