I hate to water the lawn. There was a sprinkler system here when I moved in, but it had so many problems that after spending too much money and time on it, I gave up. I now use a hose and discovered a cheap system of several short hoses and sprinkler heads that cover a larger area without waste. That works for me, but I still hate to do it. Not just the watering, but paying the bill. I have noticed that my water bill is less now that I don't use the sprinkler system, though.
Do you have a sprinkler system? (Dollar Stretcher ran an article about maintaining one - that's what started this!)
My back yard is always greener and grows faster than my front yard, even though it's the same kind of grass. I don't water the back as often and I tend to ignore it when it comes to things like aeration and weed control. I think a perfect green lawn is overrated, but that's just my opinion. In some areas I know watering the lawn is a bigger concern than others because of rainfall.
Anyway... the point to all this rambling is: What do you do to save water on the lawn and garden?
