HOW TO MAKE NEW PLANTS
Lovage is a perennial herb, and this means that it dies down in winter but only to its roots, leaping back into life with new, fresh growth each spring. It will grow in a pot for a short time but is best planted out in the long term. Leave the dead stems throughout winter and insects will make use of them for overwintering, then cut back in spring. Start from seed in spring or summer: sow seed thinly across a seed tray or shallow pot and water well. Thin out and pot on into individual pots, to plant out the following spring.
