Roman Chamomile Seeds

Sow Roman Chamomile seeds in early spring, 4–6 weeks before the last frost, or put seeds in the ground in fall and let them stratify naturally over winter. Roman Chamomile seeds need light to germinate, so press them onto the surface of moist starting mix and leave them uncovered. Keep soil temperatures between 65 and 75°F and you will get the best germination rates. Expect sprouts in 7 to 14 days. Once seedlings hit about 2 inches, thin to 8-inch apart to avoid overcrowding.

Roman Chamomile needs at least 5–6 hours of direct sun to grow well, though it handles partial shade pretty well. Soil should drain well. If your soil is heavy clay, mix in coarse sand or grit before planting. Water regularly through the first season while roots establish, then back off. Established plants handle dry spells without trouble, and overwatering is far worse than underwatering.

Mow or trim plants back a few times during the season to keep the mat tight, trigger new growth, and extend flowering. Untrimmed plants get leggy and open up in the center. For tea or medicinal use, pick flowers when they're fully open; dry them in a single layer at room temperature to preserve color and oils. Every 2–3 years divide established clumps.
