sow the seed onto the surface of a seed or multipurpose compost. Cover lightly with compost and keep slightly moist and in a warm 15-18 degree c environment. when germinated you can reduce the heat and when big enough to handle you can pot them on to small pots etc.

Hi, welcome to GoY, sow the seed of catmint, { nepeta} in autumn, put them in a cold frame, either in pots, trays, or a seed bed, you can divide them in spring or autumn, or you can take softwood cuttings in early summer, a lot of catmints self seed, but not all, Derek.
