weeds and moles

A few comments. The orange butterfly weed is a huge spreader in warmer states. It is all over New Mexico and marching east and west. I got a terrier for the moles, he has caught two mice and dug up my perennial boarder beyond recognition. However, he is a love. As for moles, they spread your bulbs nicely and you get a wonderful mix in the spring. The bulbs that I want to keep identified I grow in raised beds with bird screen in the bottom. However, these are miniatures and do not take up a great area. None of this is much help is it?
