Should I soak rosemary seeds before planting?

Rosemary seeds take a long time to germinate, so it is best to soak them for 2 to 5 hours before sowing. A growth stimulant can be added to the water to promote germination. Because of its poor germination rate, seeds should be sown early, around February.

Does rosemary come back every year?

Rosemary is a perennial herb, so it will continue growing year after year in containers. This can result in pot bound plants. A pot bound rosemary plant will produce less and less new growth and get quite woody.
