I have a couple of questions. When its dry and we have lack of rain typically the lawn goes brown. Why is it that crabb grass stays green? Is there no way grass seed manufacturers/suppliers can isolate the gene or property in crabb grass and put it into standard grass so it will also stay green in drought times? Second, I have two dogs and the dogs urine will pretty well kill the standard lawn grass, however when they urinate on crabb grass it does not die or even turn brown, can they also put that gene/property in the standard lawn grass?
