How to grow Rosemary
While frequently grown from cuttings, rosemary will do well grown from seed. It is slow to germinate and requires 14-21 days at 60 or so degrees to germinate. Sow seeds in pots or flats, cover them with 1/8th inch of soil mix and keep well watered until they germinate. Transplant to individuaI containers once they are large enough to handle easily. Set outside and space at 18-24 inches. Rosemary is completely hardy in zones 8-10; in those areas, you can have a rosemary hedge. Traditional wisdom is that in other areas you need to dig it up and bring it inside for the winter. However, with protection from ice & snow, rosemary will survive at temperatures much lower than the often quoted 20 degrees F (-6 C)
