Frequently Asked Questions

Our Service and Treatments

Is Green Thumb's service safe for children/pets?

The products that we use are of minimal risk to children and pets.  However, because we are sometimes applying pesticides, it is important that we all act responsibly.  Please make sure to keep small children and pets off of the treated area for 24 hours after application.  Once this time period has elapsed, families are free to enjoy their lawn in all the ways they usually do.


Keep in mind, by allowing Green Thumb to care for your lawn, it is no longer necessary for you to store lawn care materials inside your home.  Green Thumb technicians are highly trained and NYS certified.  We only apply what is necessary, and do so in a responsible manner.

How long should I wait to walk on the lawn after it has been treated?

As recommended by the manufacturers of the products we use, please keep small children and pets off of the treated area for 24 hours after treatment.  Once this time period has elapsed, families are free to enjoy their lawn in all the ways they usually do.

How long should I wait to mow the lawn after it has been treated?

Because many of the products that we use for weed control are liquid, they are designed to absorb into the plant tissue and work its way through the inside.  In order for this to work as effectively as possible, we ask that you do not mow the lawn for at least 24 hours.  In the instances where we have treated for emerged crabgrass and/or nutsedge (usually in the summer), it is often beneficial to wait a full week before mowing the lawn.

Why does Green Thumb's service start later in the year than other companies?

Green Thumb will always put the needs of your lawn first.  For this reason, if you are a returning customer, your early spring application will typically occur a little bit later than those who are new to the program.

Here is why:

Your late fall winterizer is applied at a time where the lawn is beginning to go into dormancy.  The lawn will not use all of the available nutrients at this time.  In fact, most of these nutrients are stored over the winter.  This is done purposefully, so that when the lawn comes out of dormancy in the early spring, there are plenty of nutrients available to provide the turf with a quick burst of green.


Also, we would prefer that our customers get the most out of each treatment.  By waiting until weeds begin to germinate in the spring, we can be sure to nip these unwanted plants in the bud.  The spring is one of the best times of the year to control weeds.  If the first treatment is done too early, it will not affect them and weeds will instead grow rapidly throughout the lawn.


Finally, crabgrass is probably one of the most difficult to control weeds.  Thankfully, Green Thumb uses the most effective controls available but the timing of the application is essential!  If a crabgrass preventative is applied too early, it will breakdown with rain and sunlight, and lose its effectiveness by the time we reach mid-summer.  All of this boils down to one simple point: When it comes to lawn care, timing and patience are critical.

Why do other companies offer more yearly treatments than Green Thumb?

Lawns in this area require a certain amount of fertilization throughout the year.  Our experience and knowledge of the area has proven that 5 treatments (every 5-8 weeks) ensures the best results.  Our program is designed to supply the grass with all the nutrients required, and each treatment is balanced in such a way as to correspond with the weather.  Along with these treatments, we come prepared to tackle other concerns such as crabgrass, weeds, surface insects, grubs, and disease.  There are times when the lawn may require additional treatment in between scheduled visits.  We are happy to apply most of these necessary services at no extra charge!

What are those brown spots on my lawn?

Unfortunately, the appearance of brown spots in the lawn could be the result of any number of things.  Grubs, surface feeding insects, disease, drought, and dormant grasses are just some of the possibilities.  We advise not to take these problems lightly.  Ignoring the problem or misdiagnosis only allows for matters to worsen.  Contact us right away and let Green Thumb figure it out for you!

I have moles. Does that mean I have grubs?

No.  Moles do eat grubs, but their main diet is actually earthworms.  A better way to tell if you have a grub infestation is from skunk damage.  Skunks will dig up the lawn severely when grubs are present.  Also, if there are grubs in the lawn, the turf will pull up like a piece of carpet because the roots have been eaten away.

Does Green Thumb control moles?

No.  Although we do guarantee control of grubs, and use products that minimize surface feeding insects, we cannot guarantee control of mole activity.  Moles primarily feed on earthworms, which tend to thrive in healthy soils.  Furthermore, moles will be more active in lawns that are close to wooded areas.

Does Green Thumb control earthworms?

No.  Part of our role in lawn care service is to add essential nutrients to the soil, which in turn create the proper conditions for a healthy root system. Earthworms will thrive in healthy soils. Although we take measures to control all turf-damaging insects, the available products do not control earthworms.  This should not be discouraging, as earthworms do us the favor of naturally aerating the soil to allow for reduced soil compaction, better airflow, and turf root expansion.

Does Green Thumb control ants?

Our surface insect control will temporarily minimize ant activity.  The problem is that most ant colonies are located much farther down into the soil than our products are designed to leech.  So essentially, only those ants that are close to the surface and come into contact with our insect control will be affected.  The best way to keep ants and their mounds from entering a lawn is through a thick and healthy turf root system.

Does my lawn need lime?

This is an important question.  If the soil pH in your lawn is not properly adjusted, our materials will not work as well and certain weeds may tend to thrive in these conditions.  Typically, the soils in our area tend to be acidic, and require lime in order to lower the acidity and balance out the pH level.  Our experience tells us that applying lime every two years is a good preventative maintenance practice.


However, because each lawn is unique, the environmental conditions on your property may be different than the average.  It is extremely rare for us to find a lawn where the pH is too high.  Often it is a just little too low and lime is beneficial.  Sometimes, the pH is very low, and lime needs to be applied heavier and more frequently.  Properties containing pine trees are always good candidates for lime treatment.

My lawn had leaves on it when it was treated. Will it still be effective?

The late fall application is applied in granular form.  These fertilizer pellets are designed to roll off of moderate leaf cover.  If the leaves form a blanket over the lawn and are wet, they may hinder the transportation of the product to the soil.  In this case, your technician will simply leave you a note that he was there, and ask you to call us when the leaves have been raked so that we may apply the treatment effectively.

It rained right after my lawn was treated. Will it still be effective?

Most likely, yes.  We have been very happy to learn that most of the products we have been using are enhanced by light or moderate rainfall.  Of course, there are exceptions to this.  If the rain is too heavy, it is possible for some weed controls to lose effectiveness.  Aside from that, all fertilizers, granular products, and insect controls need water in order to work properly.


If you receive a treatment, and the weeds do not start to wilt after 2 weeks, feel free to contact us, and we will be happy to return to your property and retreat at no charge!

Billing and Payment

What are my payment options?

99% of our residential customers either pay for the year in advance or make eight monthly payments throughout the season.  By paying in advance, returning customers enjoy an extra 5% off of the cost of the service.  Otherwise, the monthly payment option is suited toward those who prefer to pay their bills on a monthly basis.


If neither of these options are suitable for your needs, please let us know, and we can tailor a payment method that will work for you!


Green Thumb accepts cash, checks, and money orders.

Does Green Thumb accept credit card payment?

No.  In order for Green Thumb to keep our prices as low as possible, we do not accept credit card payments at time.  Green Thumb accepts cash, check, and money orders.  For further questions regarding billing and payment, feel free to contact us.

Lawn Maintenance

When is the best time to water my lawn?

Believe it or not, this is an easy question.  To keep things simple, we have found that most lawns thrive when watered daily.  Watering amounts depend on weather, but 15-20 minutes per area is about average.  Typically, watering in the early morning is the most beneficial.  Never water at night, this can bring out diseases in the turf.

Should I bag or mulch my grass clippings?

Most of us believe that mulching the grass clippings is very beneficial when developing a thick and healthy lawn, especially when it is being fertilized consistently.  The reason is that once the fertilizer is absorbed into the grass plant, many of those nutrients are stored toward the top of the grass blade.  By returning these clippings back down into the soil, it recycles the nutrients and allows the turf to maximize the benefit of each treatment.


Keep in mind, when the lawn is growing quickly, such as in the springtime, it is possible that these clippings can build up on top of the thatch layer.  During these circumstances it is advised that clippings are bagged every other mowing.

When is the best time to seed?

September is the best time of the year to seed your lawn.  The weather is cool, the soil holds more moisture, and crabgrass is no longer germinating.  We strongly suggest using this time as an opportunity to fill in those thin areas or bare spots.


Although spring may seem like a prime time to seed, it is not.  Those who attempt to seed in the spring usually wind up with patches of crabgrass and weeds by the time the summer hits.  If you do choose to seed during this time, we will not be able to apply pre-emergent crabgrass control.
