It's safe to plant as soon as the Roundup dries. I usually wait until the weeds or grass starts to turn yellow just to give the herbicide a chance to work. The time differs according to the temperature. The hotter the quicker. Kate, welcome to the wonderful world of Queen Anne's Lace. Someone gave me some seeds a few years ago and the rest is history.

Okay, as a follow-up piece of information, I just discovered that the more bare part of the hill has a few jack-in-the-pulpits in the shadier parts, fi that gives any context as to soil and light conditions (though from what I've read, these wildflowers can grow in a variety of conditions).

A possible is to heavily lime the area. I know when I had an overload of sorrel, changing the soil pH in the growing area certainly made it's life very difficult. If you grow fine azaleas/rhodos then you probably have a soil pH between 6.5 and 5. If you can get it over 7 and hold it there for a few months that could help. The other areas where you may be able to intervene are: in the amount of moisture available to the plants. Going from reliable wet to rare and droughty can be useful; and the amount of sunlight the area gets. And gross feeding through adding compost can change the environment enough to suppress the plants. [Though some are thug enough to just lick their collective chops and go for more...:-( ]

Delgardner, I have had great success with Sweet Woodruff. It is a low growing ground cover, looks delicate but is tuff as nails. It grows like a mat covering and choking out weeds. It is easy to transplant, each year dig out chunks and press into loose soil. Looks beautiful and gets tiny white flowers in the spring. Extremly low maintnence. May have to pull some weeds when it is getting established but after that it comes back every year with a vengance. Attatched a link with a good picture of the plant. Also for dry shade try ribbon grass, the english ivy, creeping myrtle vinca, varigated vinca, lily of the valley, with "caution" bishop weed, and also with "caution" crown vetch. Ground covers seem slow at first but once established look out!........Good Luck.........Dianne Here is a link that might be useful: Sweet Woodruff
