"...and he is not making money on me."

That says it all right there.

Too many guys call themselves landscapers yet know very little about plants. They're just an adult version of preteens who once roamed the neighborhood looking to cut yards for pocket money.

I remember before the housing bust, when many single women moved out of apartments and into homes, every other truck I passed on the street, and even some family vehicles, had a hitch attached. They all claimed to be in the landscaping business.

What is this guy doing that you can't do yourself?

There are growth inhibitors, but they are rather expensive and work better on short cut grass rather than home lawn heights. Home-owner lawn nuts usually use it to suppress seed heads. Primo is one.

Get a new landscaper.

Do you have a real lawn or is it mostly weeds? Weeds grow faster than grass. Also you mention the use of a fertilizer, lawn restore 2, I checked their website and it says that they now recommend that 1 bag cover 5,000 sq/ft - double what the earlier product covered. Check how much fertilizer you have been putting down by double checking the application rate.

If you have put it down correctly then perhaps your lawn guy has other clients who don't fertilize at all and perhaps your lawn is in better shape than his other clients.

I would also think about replacing landscapers, anyone who knows anything about grass knows that grass grows faster when given lots of water, food and warm weather.

Hey guys...instead of silly comments that diss on the lawn care professionally how about we answer the question. I know for a fact where I live (Ohio) in the spring if you use fertilize you have to cut your yard almost every 3 days during the growing season. It takes me 2-3 longer to care for a yard like this then a short and poorly cared for yard. 3-4 inches of grown in 3-4 days is not unheard of! Most people with quality lawns need them bagged so one pass...and you bag...one pass...and you bag.

Primo Maxx cut down my mowing by at least 50%. I keep my grass at 3.5". There's a generic available for much less than the Syngenta product.

Lawn Restore does have some fast release fertilizer with the distillers grain. How often are you applying it and how much per 1,000?
