Step by step
- On planting day
Plant
Plant at the same depth as in its pot, 60 cm apart, in a sunny, sheltered spot. Firm in.
- 0–1 days after “Plant”
Water In
Water well, then keep just moist while it settles in.
- 30–51 days after “Water In”
First Light Harvest
Once it is growing strongly, snip a few sprigs — never more than a third of the plant at once.
Every year
- MayTrim After Flowering
Lightly trim after the spring flowers to keep it compact. Never cut into bare old wood.
- JulyHarvest for Drying
Cut sprigs on a dry morning and hang in bunches to dry.

Move pots against a sunny wall and raise them on feet; rosemary dies in cold, wet compost more than from cold.
