Snip off several 4-inch lengths of an existing Lamium plant. Strip the lower leaves by cutting them to the stem with scissors or your fingernails.
Prepare small pots with drainage holes by filling them almost to the top with standard potting soil. Water well, until water runs out the holes. Poke one hole for each cutting with a pencil or screwdriver.
Dip the stripped end of each cutting into a rooting hormone according to product instructions. Gently insert the dipped end into one of the holes you made in your small pots. Fill in with additional potting soil.
Keep the soil moist and keep your cutting in a fairly cool, shady place until you see new growth. White roots will later begin to appear at the pots' drainage holes; when this occurs, transplant successfully rooted cuttings to the garden or to larger pots.
Remove several clumps of an existing stand of Lamium by digging them from the soil with your trowel. Small pieces that measure 1 to 2 inches in diameter are best, but make certain each clump has some roots.
Fill small pots with drainage holes to about ¾ full with standard potting soil. Water well, until water runs out the holes.
Set one clump of Lamium on top of the soil and fill the pot with additional potting soil, gently pressing it down around the base of your rooted clump.
Water your potted clumps of Lamium again. Keep them in a shady area until they begin to spread and grow.
