I just bought a new house with 2 and 1/2 acres of land and it needs a serious
detatching. If I powerrake the lot do I need to rake it up (seems like a lot
of work - unless I borrow a tractor with a bag attachment)? Or, do I just
leave the clippings on the lawn? This second option seems like it would defeat
the purpose of detatching in the first place.

Leaving the thatch would defeat the purpose. Once it's raked out of the turf, it
should move around fairly easily. You can sort-of roll it up into balls like
tumbleweeds, and then collect the balls.


Secondly, can I aerate right after I detatch? If so, do I need to flag all 67
heads of my sprinkler system heads so they don't get aereated?

Yes, you can aerate after dethatching. You can even leave the plugs on the lawn.


Lastly, the entire lawn is Kentucky Blue Grass. Is it best to use a different
type of grass when I overseed?

Most grass seed comes in mixes. Generally a lawn isn't going to be a single
monoculture of grass, but a mix. What that mix is will be dependant on a number
of factors: Your climate, your soil type, the exposure to sunlight, and
irrigation plans are some of the big ones. Check with your county extension
office to see what mixes they recommend for your conditions. Then, if they don't
give you specific brand names, you can go to your local stores, and start
reading the labels to find a mix that matches or comes close to what you need.

The best time to renovate a lawn is after the heat of summer, just before the
rains of fall, with long enough time for new root development before any winter
frost. Spring is the second best time, but you may run into problems with wet
turf while you're dethatching and aerating, and then you may need to manually
water the lawn after seeding. You might want to consider whether your time would
be better spent on other new house issues, put up with a so-so lawn this summer,
and hit it full-on in the fall. The exact window of time is dependant upon the
climate where you are.
