When to Plant Lemongrass in Unknown

Growing Lemongrass in Unknown: Complete Guide

Lemongrass (Cymbopogon citratus) is a warm-season crop that needs a head start indoors before Unknown's last frost. Depending on your zone, Unknown gardeners start seeds indoors between December 2, 2026 (Zone 9b) and March 1, 2027 (Zone 5a), then move transplants outside once their zone's last frost has passed — the zone table above has your exact dates.

Because Unknown stretches across 6 USDA hardiness zones (5a, 7a, 7b, 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 100 days to maturity, Lemongrass needs the indoor head start that Unknown's growing season requires. Starting indoors ensures you have strong transplants ready the moment outdoor conditions are right.

Lemongrass requires full sun (6-8 hours) and moderate-high (1-2 inches/week) moisture. Check your local forecast for humidity and heat advisories that may affect timing and pest pressure.
