Planting Sage Indoors
You can grow sage from seeds, cuttings, or small starter plants.

- Starter plants: Garden centers often sell young sage plants ready for repotting indoors.
Caring for Indoor Sage
Once established, sage is a very low-maintenance herb.
Watering: Allow soil to dry slightly between waterings. Sage prefers drier conditions.
Feeding: Fertilize lightly once a month with a balanced liquid feed.
Pruning: Pinch back stems regularly to encourage bushy growth.
Airflow: Place near a window or fan to reduce risk of mildew.

Harvesting Sage Indoors
Begin harvesting when the plant reaches 6–8 inches tall.
Snip stems just above a pair of leaves to promote regrowth.
Fresh leaves can be used immediately or dried for long-term storage.
For strongest flavor, harvest in the morning when oils are most concentrated.
Common Problems When Growing Sage Indoors
Though sage is tough, a few issues may appear:
Powdery mildew: Prevent with good airflow and avoid overhead watering.
Yellow leaves: Usually caused by overwatering.
Leggy growth: Move closer to a bright window or add grow lights.
