Weather is warm now: Dethatching and Aerating
So temperatures have started picking up here in the desert the past 2 weeks. We've been 70-80 high every day and 40's overnight. I haven't started watering the lawn yet, it's all brown still. I have a tall fescue lawn in my back yard, about a 1000sq ft lawn. Should I start watering regularly now? Our average last frost date is April 10th...so I'm worried it may freeze again.
I started dethatching using a manual thatch rake (man is that tough work!). I mulch mow, so there was about an inch of thatch easy, and the grass was really scratchy/crispy/and it hurt to walk on barefoot. That's why I'm getting rid of the thatch. Is it okay to start watering now, or should I finish dethatching first? It's going to take a week or so to totally finish dethatching; I just do an hour or two every night.
Also, should I core aerate again when I'm done dethatching? I haven't done that for a year. I plan to overseed and fertilize once I'm all done since the grass is pretty thin after dethatching.
