Hi Bill,

I used a dethatching tool that has a series of moon-shaped blades on
it. It worked really well in removing thatch, and it was a workout to
complete a half acre. The cause of the thatch was drought conditions
that killed a lot of grass. Grubs can kill grass too. Apply the
fertilizer at half rate, unless it is an organic type. Thatch buildup
can be more of a problem in areas that are not full sun. It would be
helpful to find out the cause of thatch and soil compaction, then
remove the cause.

I have large areas in my lawn that need dethatching. On a
recommendation of a friend I purchased a Liquid Composter & Dethatcher
which is an enzyme you spray on that produces a bacteria that is
supposed to accelerate the natural decomposition of lawn thatch.

It is also time to spread the crabgrass preventer and fertilizer.
Keeping in mind I'm having the lawn aerated soon, please let me know
your opinion:

Aerate
Spray dethatcher
Wait a week
Fertilize

or

Aerate
Fertilize
Wait a week
Spray dethatcher


Thanks to all.
