When to Plant Chamomile in Arizona

Growing Chamomile in Arizona: Complete Guide

Chamomile (Matricaria chamomilla) is a warm-season crop that needs a head start indoors before Arizona's last frost. Most Arizona gardeners begin seeds indoors around Sunday, December 14, 2025 and move transplants outside around Sunday, February 8, 2026, after the risk of frost has passed.

Because Arizona stretches across 10 USDA hardiness zones (5b, 6a, 6b, 7a, 7b, 8a, 8b, 9a, 9b, 10a), 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, Chamomile needs the indoor head start that Arizona's growing season requires. Starting indoors ensures you have strong transplants ready the moment outdoor conditions are right.

Chamomile requires full sun and regular moisture. In the arid Southwest, intense sun and low humidity mean irrigation is essential; mulch to prevent rapid soil moisture loss.
