I have picked up a couple of new accounts with lawns that have large sections of zyosia, maybe 55% of the turf, with some cool season rye/blue mixes on the other 45%. Small properties, maybe 4k of turf at the most. I know zyosia needs to be dethatched, but how the heck do I put together a plan for these properties, considering that any aeration, power rake, slit seeders or dethatching machines I would have to rent. I can't see dethatching the zoysia and slit seeding the cool season grasses later on... that sounds like too much trouble and too expensive. I hate the idea of raking the stuff... too labor intensive. Should I just bite the bullet and take a hit on renting a power rake? One account in particular is very cost sensitive, a elderly woman. It would be hard to bill out the overhead on renting two kinds of machines. Besides, I like to do my over seeding in the fall. Is there any simpler, easier way to deal with these half an half lawns? Man, I hate zoysia.
