Frequently Asked Questions about GreenGrass Services




Do I need to sign a contract? All our services are verbal service agreements.


May I cancel at any time? You are free to cancel any service at any time.  Just be sure to let us know.  Our program services - Lawn Care, Bed-Pre-emergents and Mosquito Control - are like cable TV or a newspaper subscription, so we will continue to come out unless you notify us otherwise.  Services that are paid monthly over a year will be pro-rated according to services already performed and payments already made.


What is your guarantee?  If you’re not happy, we’ll be back!


Are you privately owned?  Yes!  We are Oklahoma-owned and operated since 1996.  No stockholders to please, so we make our own decisions!


Do I have to be home when you come out?  Not at all.  We will treat your lawn and leave your invoice and information about the application on your door.  If you have a gate to unlock, or a dog to put up, we can leave you a message the day before we come out, or email you a reminder.


What if it rains right after my application?  It will probably be just fine.  Pre-emergents and fertilizer need to be watered in.  Broadleaf weed control (post-emergents) may or may not be affected by rain.  In any case, if you’re on our full program, your applications are guaranteed.  If you don’t see results within 10-14 days, just give us a call and we’ll be happy to come back out and treat at no charge.


May I mow or water right after an application was done?  Rule of thumb is wait 24 hours, then water, then mow, in that order.  If you want to wait longer than 24 hours to see if it rains, that’s fine.  Just be sure the application is watered in before you mow.  If there are no visible weeds in your lawn, you may water right away.


Do I have to water my lawn after you do an application? Watering an application within 10 days if no rain is a good idea to insure maximum effectiveness.  Just remember that you should always water an application before you mow.  Many times, morning dew will do the job for you.  If you cannot water or forget to water, it will probably still be fine. 


What are those brown spots in my lawn?  Any number of things can cause brown spots in your lawn, depending on the time of year and weather conditions.  It could be winterkill or Spring Dead Spot in the spring – these are areas that did not green up with the rest of your lawn.  If it was green and then turned brown, it could be a fungus like brown patch, insects like chinch bugs, or simply a lack of water where your sprinklers are missing, or where the soil is compacted more than the rest of your yard.  It could be buried construction debris or a large rock buried in the ground (a soil probe or long screwdriver can usually find that.)  


Can you get rid of my moles?  We can treat your lawn with an insecticide which will eliminate grubs and other insects.  Sometimes that removes the food source, but sometimes it doesn’t.  We can’t guarantee that it will rid your yard of moles.  OSU Extension recommends traps as the best way to deal with moles.  You can find these at your lawn & garden center or CoOp.


I see a lot of ants in my lawn – will they hurt anything?   Ants are considered a nuisance pest and will not harm your lawn.


Are the applications safe for my pets and kids, and wildlife?  When we do liquid applications, we recommend that children and pets be kept off the lawn until it’s dry.   This is just a safety precaution, in case a person or pet happens to have specific allergies.  We have never had an instance of anyone getting sick or any wildlife being adversely affected.  The materials we use are generally less toxic than most household cleaners or the pesticides sprayed on fruit.


How often do you come out?  Lawn care applications can be anywhere from 4 weeks to 8 weeks apart, depending on weather conditions.  Obviously, during the growing season, applications are closer together.  During the early spring and late fall, they’re farther apart.


Can you treat weeds in the flowerbeds?  We sure can!  Flowerbed weed control consists of three applications, usually one in February,  one in April, and the last in November (depending on weather,) and touch-ups as necessary.   100% of your weeds won’t be eliminated, but it will cut down weeding time tremendously (like 10 minutes instead of an hour.) 


How long will it take to get my yard looking good?  That depends on when you start the service and the shape your lawn is in.  If you start at the beginning of the year, you will get both crabgrass pre-emergents and broadleaf weed controls, and that will help tremendously.  If you start in the summer and your yard is already full of crabgrass, then it will be a struggle to overcome that in the same growing season.  Likewise, even if you start at the beginning of the year, but your yard is a mess with lots of grassy weeds and thin turf, it may take a full growing season.  Our lawn care program is not a miracle cure, but you will see an improvement with each application.


I haven't missed any applications, so why do I see weeds?  Weed control is an ongoing process.  Even though we put down pre-emergents and spot spray weeds when we see them, weed seeds can remain in your soil for years.  (That's why you always get weeds in your flowerbeds - you're always digging around in there, and it disturbs dormant weed seeds.)  Not only that, but wind, rain and animals spread seeds around, too!  Birds eat seeds and poop them out on your lawn.  It's a constant onslaught!  Healthy turf will choke weeds out.  If you have areas of thinning turf, like under a tree where the shade increases as the tree grows, you will have a hard time keeping weeds out of there.  If the shade is encroaching, it's best to seed shade grass under the tree, or see our shade solutions page for some other ideas.
