When the hosta "eyes" appear, I mix one part household ammonia with ten parts of water and pour this mixture around the eyes close to the plant. It doesn't hurt the plants, but it does dissolve the eggs that are laid around the roots. It has reduced the slug population noticeably. I also pour the ammonia solution directly on slugs that I see on the deck. Dissolves them right away.
Phlox stolonifera with Bloodroot, Vinca, Columbine and Hosta. I’ve found that this is a shallow rooted plant. Keeping it out of the hot afternoon sun keeps the soil from getting too dry. While it has tolerated some dryness I haven’t taken a chance to see just how dry it can get. During the summer I water the area a little if we haven’t had rain.
