When to Plant Rosemary Seeds

Plant seeds indoors 6-8 weeks before the last frost of the season, or sow outdoors once soil temperatures reach 65°F.

Where to Plant Rosemary Seeds

Rosemary should be sown in lighter loamy soils that are dry and well drained. Plant in full sun (6-8 hours of sun per day) for best results, but it will tolerate partial sun (4-6 hours of sun per day). Rosemary prefers soils that are slightly acidic. Wet soils that don’t drain well often kill Rosemary. Avoid clay soils.

How to Plant Rosemary Seeds

Before planting, we recommend soaking Rosemary seeds for 24 hours to encourage germination. Learn more about here.

Rosemary seeds require light to germinate, so be careful not to cover them when planting. Learn more about germination light requirements here.

Sow the seeds directly onto the soil and do not cover. Keep the soil moist but not wet until germination. As the seedlings get larger, thin the plants out until they are 12-18 inches apart.

How to Harvest Rosemary

Sprigs and leaves can be snipped off of the plant at any time during the growing season, but trim before blooming for the best results. Rosemary can be used fresh, be frozen, or be hung in a dark, cool, dry place such as a garage to use later.
