About Rosemary
Rosemary brings narrow, aromatic leaves and an upright form to a sunny kitchen herb garden. Choose a sunny position with free-draining soil and avoid waterlogged roots.
When to Plant Rosemary Seeds
Start indoors well ahead of the last frost; seed-grown rosemary can germinate slowly and unevenly.
Where to Plant Rosemary Seeds
Choose full sun and sharply draining soil or a pot with drainage holes. Avoid a location that remains wet after rain.
How to Plant Rosemary Seeds
Sow seed shallowly using the packet’s depth and any preparation instructions.
Keep the seed mix lightly moist, warm, and bright while seedlings develop.
Move sturdy young plants into individual pots, then harden off before planting outside.
A commonly listed sowing depth for this type is 1/16 inch; verify against the supplied seed lot; check the actual packet before sowing. Use the packet to confirm final spacing; a general reference is 12 to 18 inches; verify against the supplied seed lot.
How to Harvest Rosemary
Snip young, leafy sprigs as needed during active growth, leaving enough foliage for the plant to recover. Use them fresh or dry small bundles in a warm, airy place out of direct sun.
How to Care for Rosemary
Water newly transplanted plants regularly, allowing drainage between waterings. Once established, avoid overwatering and trim tender tips for cooking without stripping woody stems.
Companion Plants
Place with lavender in a sunny, well-drained herb area, allowing room for both to mature.
