I have a small flower planting area of about 25 sq. ft. When I plant
flowers in it each summer, the weeds come up so bad, I can keep up with
weeding it each week. (I also much about 3 or 4 inches, but that doesn't
stop these weeds).

Before I plant flowers, if I soak the ground with Roundup, how long would I
have to wait to plant the flowers ?

thanks !!
