How to Grow Sage

Sage is the Thanksgiving herb that earns its keep all year. The silvery-green foliage is ornamental in its own right, and the blue-purple flower spikes attract pollinators. Like rosemary, sage is Mediterranean in origin and despises wet feet. The first year's growth is modest; by year two, plants are lush and productive. Purple sage and tricolor sage add ornamental value but are less hardy than common garden sage. Harvest before flowering for the most concentrated flavor. Rubbed sage (dried and crumbled) is the form most people know; fresh sage has a more complex, less dusty flavor.

Starting Seeds Indoors

Begin sage seeds indoors 6 weeks before your average last frost date. Seeds need soil temperatures of at least 60°F to germinate, which typically takes 10-21 days. Provide 12 hours of light per day using a south-facing window or grow lights.

Transplanting

Move seedlings outside 1 weeks after your last frost date, once soil temperatures reach 60°F. Harden off seedlings for 7 days before transplanting by gradually exposing them to outdoor conditions.

Direct Sowing

Sage can be direct sown 1 weeks after your last frost date. Plant seeds 0.125" deep, spaced 24" apart.

Growing Tips

Prune in spring to encourage bushy growth. Replace plants every 3-4 years when they get leggy. Excellent dried for winter cooking.
