Sowing Guide

Early Sowing/Module Sowing

Sow the rosemary seeds thinly on the surface of moist compost in trays, modules or pots.
Lightly cover with some fine compost.
Place in a propagator or clear plastic bag and seal, germinate at the temperature suggested above. The germination tends to be erratic and can take a few weeks.
Once germination has started remove from the propagator or bag and place in a cooler but not cold location. Protect from frost.
When the seedlings are large enough to handle transplant into 7 - 10 cm pots.
Grow on in a frost free greenhouse or cold frame.
Plant out when all risk of frost has passed and the plants are growing strong.
Harden off over 7 - 10 days before planting out.

Direct Sowing

Germinate indoors for best results.

Growing On

Water the young plants well until established.
Established plants will need watering frequently especially in dry weather.
The plants will have grown into a large bush by the second year.
After flowering in early spring prune any new growth with garden sheers. This should be repeated again in mid summer. Regular trimming will keep the rosemary plants tidy and encourage a bushy, compact habit.


The leaves can be harvested at anytime however they are at their best in spring when fresh new shoots emerge.
Snip the stems with scissors or secateurs as and when needed.
The leaves can be used fresh, dried or frozen.


When trimming, avoid cutting too hard back into old wood as the plants will rarely recover. Exposed old wood will not re-grow and will look unsightly.
