How do I plant dead nettle and get it to spread in my garden?
Spotted dead nettle (Lamium maculatum), like many perennial ground covers, has the ability to send out new roots from various points along the stem. In fact, you should find roots wherever the stems come into direct contact with the soil. That said, you can dig up a section of the dead nettle and replant it in your garden. Work the soil before planting; if you're planting more than one piece, place the roots several inches apart. Keep them watered well, and fertilize in spring or early summer to help them spread faster.
