Hi everyone. I have been fighting an ongoing battle with my front lawn, it is a sloped lawn that is in FULL sun all day long. The lawn would always burn out in July and get taken over by crabgrass, I would scratch it up and overseed in the Fall and the cycle would repeat again the next year.

At first I thought the water I was putting down was mostly running off the lawn into the street so last Fall I rented a plug aerator and ran that through, this seemed to loosen up the soil and I saw less water out in the street. In the Spring I put down lime and later a pre emergent crabgrass killer, I also raised the height of my lawnmower to keep the grass around 3" high to choke out the crabgrass. I put an automatic timer on the grass and watered it every morning for 15 mins, I even tried twice a day for 10 mins each but the lawn again burned out and crabgrass took over.

With Fall approaching I was thinking of renting a split seeder (power seeder?) and overseed with that but don't want to waste the money if the same problems come back next year. What can I do to solve this problem? What is the best type of grass for zone 5 (Rhode Island) in full, and I mean full sun?

Since the lawn is so far taken over am I better off tilling the whole thing over and power seeding then or should I wait a few more weeks until the cooler weather hits? I want to fix this problem once and for all, any help is appreciated.

Fescue is better than KBG for this situation. My guess is that you soil structure is less than desireable in that water does not easily soak in. Compost rather than fert. 3" mowing height is fine in spring and fall but 4" is better for summer. [no mowing at all if grass starts to dry up]

If you start over be sure to address how much OM you ammend to the soil. OM holds moisture and is necessary for soil structure. Nothing can replace that.

I am going to send off to the University of RI to get a soil analysis, it only costs $8 and may give me some more info on how to amend the soil properly. I plan on slit seeding, raking in some OM over the slits, starter fertilizer and water. What is a good amount of watering to get things going? 15 minutes a day at around 5 A.M?

Watering is not a one size fits all scenario, especially on a slope.

I would soak the ground for a while, give it time to soak in then, open the ground and see how deep it went in. If you are not happy with the amount, then run it again and see if more soaks in or not.

Until you know what your irrigation is doing, everything else is a waste of time. Even if the new seed germinates and looks good this fall and the following spring. A lawn is not a lawn unless it does well in the summer when it is mostly used.
