Frequently Asked Questions

Can I mow the same day as a treatment?

Yes, but we advise waiting until it’s dry first.

Does weed control work if it rains after the application?

Yes, we use a sticker agent together with the weed control. Allow 7-10 days for weeds to fully die. If some don’t, please call us back for a free respray.

How is core aeration beneficial for my lawn?

Aeration opens the soil, allowing air and water penetration into the root zone of the grass. This process loosens compacted soil and improves root development thereby helping develop a stronger more stress resistant plant and improved thickness in the lawn.

How long does it take for weeds to die?

Some broad-leaf weeds will curl up and die almost immediately and some will take as much as two weeks to die. In any case, if there are still weeds present after 10 days simply call us or go online and request a service call and we will come right out and reapply the weed control at no extra charge.

How many applications of fertilizer do I need each year?

We recommend that you fertilize every 4-6 weeks to keep your lawn healthy and green. This generally works out to be about 7 applications a year.

I had my first application already applied. Why do I have weeds?

The first application normally contains a granular fertilizer to bring the grass out of dormancy. Since broadleaf weed control is not a preventative, it is only effective when weeds have already germinated and are actively growing. Weed control is applied with your second and subsequent applications when the weather has warmed up enough to allow the broadleaf weed control to be effective.

I have brown spots on my lawn. What are they?

There are many reasons for brown spots. A proper diagnosis by a professional is very important. It could be anything from a dog urine burn to a disease or an insect problem. Just call us for a free diagnosis. 

I have moles in my lawn. Does this mean I have grubs?

The presence of moles does not necessarily mean there are grubs in the turfgrass. The moles’ main food source are earthworms. The grubs are active only at certain times of the year and the moles will feed on them if they are an available food source.

I only have a flag in my front yard. Did you service the back yard?

Unless you request otherwise, we always treat the front and back of your yard. We only flag the front yard.

Should I water my lawn after a lawn treatment?

In most cases when using liquid weed control, crabgrass control or insect control it is not recommended to water immediately afterwards. This will allow the material to be absorbed into the grass plant. When using a granular grub control, it is recommended that the material be watered in. Please follow the directions on the invoice left at your door.

Should we dig up our weeds?

No. This common activity is extremely harmful to any lawn, since the vacant space left from the weed removal can open opportunities for new weed seeds and undesirable vegetation to grow.

The grass is very thin under my trees. How can I improve the situation?

The roots of the trees are competing with the grass for water and nutrients, leaving the grass with an inadequate supply of each. Also, the grass requires a period of direct sunlight in order to grow properly. Pruning trees, planting shade resistant grass, or planting ground cover such as pachysandra can help the situation.

What are grubs and is grub control needed on a yearly basis?

Grubs are the larvae stage of the June beetle. Damage occurs when the grubs feed on the root system of the turfgrass, causing the grass to die.

If you have active grubs in your lawn, we advise first applying a dylox treatment to control them. We then suggest a preventative application to prevent them from coming back. Next year you will only need preventative treatment and we suggest you do this treatment on a yearly basis.

What insects do you control with your perimeter treatments?

Perimeter pest control targets all crawling insects that enter your home from the lawn, such as spiders, millipedes, pill bugs, etc. Ants that encounter the product will be controlled but the nest will not be destroyed. It will not control flying insects, termites, or carpenter ants.

What is mower stress on the lawn?

There are several things that can cause mower stress on lawn. One of the most common is dull mower blades. Make sure sharpen your mower blades professionally twice a year. Never cut your grass too low, we recommend a minimum height of 3″ and finally, when the outside temperature is very hot (usually over 90) the wheels of your lawn mower can break the blades of your grass leaving brown tire tracks. Your lawn generally will recover in two to three weeks if you are properly watering.

When can I let my dog out?

As soon as the grass is dry. Usually, this is within 2 to 3 hours on a sunny day but follow directions on invoice.

When do you normally start fertilizing?

We get started when the snow clears and the weather permits. Typically, this is early to mid-March. It usually takes about 4-6 weeks to get all our round 1 customers done.

When is the best time to seed?

Early fall is the very best time to seed your lawn. Spring can also be a good time to seed if you are able to make sure the tender, newly germinated seed is adequately watered during the extremely harsh conditions that exist during the summer.

When should I water my lawn?

Lawns should be watered during daylight hours for approximately 15 minutes, at least 3 days per week, depending on weather conditions. After a lawn application is made, wait 24 hours before watering the lawn. Do not water at night because it may lead to increased disease activity in the lawn.

Why do we get crabgrass?

Since most soils are abundant with the seeds of annual weeds, they will germinate when the conditions are favorable. Ground temperatures of 75 to 80, thin turf areas, water runoff areas, and non-watered areas are favorable conditions.

Why do we have so many weeds?

Dandelions in particular, weeds in general, do not seem concerned about how long the lawn has been under good care. Airborne seed (and seed which has been in the soil for years) seek the opportunity to grow in any weak areas of grass.  Weather extremes usually create these kinds of weak areas, even in the best lawns.

Why does crabgrass seem to take over?

The rapid lateral growth of the leaves on each mature plant makes it appear that the plants are multiplying. This false appearance usually occurs in August. Crabgrass thrives in hot dry conditions, and this is why you tend to see it more in late summer.

Why does my lawn have all these long-raised tunnels?

Sounds like moles, these little critters love to eat the worms and insects in the soil just below the grass. We have a very effective way of getting rid of them.

Why is it important to put a pre-emergent crabgrass control down in the spring?

In order to control crabgrass, the product must go down early in the season to create a barrier which stops crabgrass germination.
