Weedkillers and Bulbs

My experience with Roundup is that if I overspray onto a desirable plant, 
merely wiping the leaves off  by hand or a towel saves it from 
discoloration. I like Roundup because it works through foliage only, so I 
can spray with impunity around roots and stems. I've been experimenting with 
thick mulches to prevent weed germination, but many bulbs don't like the 
extra organics in the soil.
