When to Plant Chamomile in Delaware

Growing Chamomile in Delaware: Complete Guide

Chamomile (Matricaria chamomilla) is a warm-season crop that needs a head start indoors before Delaware's last frost. Most Delaware gardeners begin seeds indoors around Sunday, February 22, 2026 and move transplants outside around Sunday, April 19, 2026, after the risk of frost has passed.

Because Delaware stretches across 3 USDA hardiness zones (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 60 days to maturity, Chamomile needs the indoor head start that Delaware'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. Mid-Atlantic summers bring heat and humidity — ensure good air circulation and watch for fungal issues like powdery mildew.
