When to Plant Lovage in Oklahoma

Growing Lovage in Oklahoma: Complete Guide

Lovage (Levisticum officinale) is a warm-season crop that needs a head start indoors before Oklahoma's last frost. Most Oklahoma gardeners begin seeds indoors around Sunday, February 8, 2026 and move transplants outside around Sunday, April 19, 2026, after the risk of frost has passed.

Because Oklahoma stretches across 4 USDA hardiness zones (6b, 7a, 7b, 8a), planting windows can shift by as much as two to four 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 365 days to maturity, Lovage needs the indoor head start that Oklahoma's growing season requires. Starting indoors ensures you have strong transplants ready the moment outdoor conditions are right.

Lovage requires full sun to partial shade and regular (1-2 inches/week) moisture. Great Plains gardens face strong winds and variable moisture — windbreaks and drip irrigation help significantly.
