I am very happy to report my backyard is now green and healthy again
I watered it twice a week, each for about 30 minutes, once in the early morning and once in the late afternoon when we went through a dry spell and the subsequent rain since has definitely helped.
I will wait a bit before mowing and spreading the fall fertilizer again. I don't plan to rip up the sod again (not for this house anyway) so I will have to be more diligent this time
I am not a green thumb by any stretch and have limited interested in gardening but it sure feels good to accomplish this. It took many hours after work and on the weekends but it is certainly much cheaper than having the guys coming in to re-seed or re-sod and I take comfort in that!
