We let grow whatever will grow in the major portion of the fields around our property, but in the area immediately surrounding the house the ratio of grass to weeds leans slightly in the grasses favor. I try to help it along mininimally from time to time by throwing out some grass seed or that dreadful (but magical) patchmaster and that seems to keep a reasonable balance. The yard has really taken a beating this summer (because we don't tend to it as a lawn with sprinklers and such) so I was going to do my usual fix it up in the fall. My question is -- do guineas eat grass seed? I have a dog that thinks patchmaster is yummy, so I have to water it in right away, which usually does the trick for the dogs, but what about guineas? Anyone have experience with this?
