To plant the seeds, gently press them into the soil a little, and then put a little more soil on top to cover them, then give them plenty of water, but don't drench them as the seeds can rot. Mugwort needs sun to grow so make sure you have a sunny area to plant them.

Cut the plants when they are tall enough, and wrap them together in a bundle when they are fresh, wrap them very tight and then hang them to dry. Sage likes sun and some sand in the soil.
