Lawn Care

Why did Swingle come out to treat for lawn mites when my yard is covered in snow?

Lawn mites like warmth. Remember that fact when you see your lawn covered in snow. Where snow has melted and grass is showing is typically where you’ll find mites. Snow covered lawns are actually very helpful when spraying for lawn mites by centralizing the mites in specifics locations. Technicians are trained to identify, while on the property, if treatment will be beneficial or not.

Lawn Care

Lawn Care

How often will my lawn be fertilized throughout the season?

With a standard 5-time lawn care program, you can expect Swingle to be on your property every six weeks. Depending on when you schedule service, lawn treatments typically begin in March after the snow melts, then again in early to mid-May. Most lawns are “cool season” grasses, which grow best from April through June.

Lawn Care

What do I do if weeds reappear on my lawn?

Our lawn weed control program provides guaranteed weed control from invasive grasses and unwanted broadleaf weeds such as crabgrass, spurge, dandelion and many others. We provide re-sprays at no additional cost should your first application not be effective.

Lawn Care

Why is aeration so important to my lawn?

Clay soils are predominant in most areas of the front range. These soils by nature are low-oxygen soils, so aeration reincorporates oxygen into the root zone. Following lawn aeration service, do not remove the plugs from the lawn. While they can be unsightly, it’s best to let them dry out and then mulch them back into the lawn when mowed.

Lawn Care

How long should I wait to mow my lawn after an application?

It is recommended you wait 24 hours before mowing your lawn (see the note below on watering).

Lawn Care

Do I need to water the fertilizer into my lawn?

We recommend that your first application be lightly watered on the day of service in order to release the product into the soil.

Lawn Care

How long should my children and pets stay off the lawn after an application?

We recommend a full 24 hours before allowing your children and pets on to your lawn after product is applied.

Holiday Lighting

Are there additional charges to replace a bulb that no longer works?

No. We’ll perform onsite maintenance to make sure your lights are working to your satisfaction during the duration of the holiday lighting season.

Holiday Lighting

What is the minimum cost for holiday lighting installation?

$750 is the minimum charge for Swingle’s professional holiday lights décor and installation services.

Holiday Lighting

What well-known locations have you designed and installed?

Denver Botanic Gardens, Hudson Gardens, Towns of Parker, Fort Collins and Superior, Lincoln Center, Whole Foods-Denver, Seven Falls and many more.

Holiday Lighting

Will we need to hire an electrician?

In most cases, no. But with larger installations, additional power sources may be required and therefore an electrician would be necessary before installation.

Holiday Lighting

Is there any extra cost to store our holiday lighting for next year?

No. Programs are all-inclusive – one price for everything. Holiday & Christmas lights design, installation, take-down, storage and maintenance.

Holiday Lighting

Do you rent the décor, lease it or own it?

All decor is included in the service package. You’ll never own old, worn-out decor again. With our program, decor is automatically replaced when it needs to be – and you’ll have the flexibility to change colors upon renewal.

Holiday Lighting

Is there a difference between our lights and the ones you buy at local retailers?

When it’s time to think about holiday lighting, many property managers will turn to their maintenance staff to deck-the-halls of their location and homeowners will run to their local big-box store. However, designing a professional holiday lighting display requires more skill and artistry than just hanging lights on a hook.

Moreover, it’s critical to be familiar with the logistics and differences between what you buy at the local big-box store and what is called commercial grade. Here are a few things to consider:

  • Many assume longer strands of lights will save time and money in the long run. But the longer the strand, the more prone they are to failure (solder points, bulb issues, wire tangles).
  • Commercial grade lights strands are typically from 50 to 100 bulbs for optimum efficiency and functionality and feature 20-gauge wire and sealed bulbs to protect from the elements.
  • LED light strands are up to 90 percent more efficient and last up to 10 times longer than tranditional incandescent strands (energysavers.gov).
  • LED lights reduce the risk of fire and personal injury – extremely important to the liability for your commercial property. LED’s have no moving parts, filaments or glass and give off considerably less heat than incandescent. Because of the reduced energy usage, they are also safer to connect end to end without overloading sockets, for ease of installation.


Can you replace the main controller on my system?

Yes. We have many options available.


Do you install complete sprinkler systems?

No. We only do sprinkler maintenance, activation and winterization.


How can I protect my back flow preventer during a freeze if they still haven’t been winterized?

Colorado is known for its rapidly changing climate. It’s important to know how to protect your home’s sprinkler system in case of an unexpected freeze and your system hasn’t been winterized. To properly protect your system from freezing and causing costly damage, there are various steps you can take to get you through the night so you can properly winterize your system on a later date. See this link for an informative video.


When should I winterize my sprinkler system?

As the weather approaches freezing temperatures, it’s important to make sure that all the water is out of your sprinkler lines to prevent damage and the expense of sprinkler repairs come the spring. Blowing out sprinkler systems as the temperatures become cooler in mid-fall is recommend.


When should I activate my sprinkler system?

As soon as fertilizer is applied to your lawn, it will require regular watering in order to achieve optimal results. We recommend activating your sprinkler system in late April, early May.


Does my automatic sprinkler system use more water?

No. You might actually find you’re saving money, as a properly designed and functioning sprinkler system waters more efficiently with less water waste.

Pest Control

Does your service protect against rabbits?

No. There is no definitive solution to rid your property of rabbit damage. Repellents and traps may work for a brief period of time, but eventually become ineffective. The best advice is to rid your property of overgrown shrubs and ground cover as well as “hiding” spots, which provide the perfect protection and home for these furry creates.

Pest Control

Does your service treat for mice?

No, we do not treat for small rodents.

Pest Control

How often will you be out on my property throughout the year to spray for bugs?

With our insect control service we’ll be on your property to spray for insects three to four times a year throughout the early spring and late fall.

Pest Control

What kinds of bugs does your program cover?

Swingle’s perimeter pest control program targets multiple species of ants, beetles, centipedes, cockroaches, earwigs, fleas, gnats, mites, sow bugs, spiders, silverfish and more.

Pest Control

The product is sprayed on the exterior of my home. Is it safe for the soil?

Yes. Our insect control spray application is specially formulated to target insects only. It will not cause any harm or damage to your soil, flowers, ornamental shrubs or lawn.

Pest Control

How long before I’ll see results?

With our insect control, you should see less insect activity about one to two days after the initial treatment, with a noticeable reduction in two weeks. The effectiveness of your first treatment is contingent upon the level of infestation and your environmental conditions.

Pest Control

When spraying for bugs, do you need to come inside my home?

No. Indoor pest and insect control is best achieved with an effective outdoor application – keeping both pests and insecticides out of your home or building.

Weed Control

Do I need to water in pre-emergent and bed and border weed control applications?

We recommend that your first weed control application be lightly watered as soon as possible in order to release the product into the soil.

Weed Control

If weeds reappear, will you come out to reapply product?

Yes, we guarantee our weed control applications and will re-spray if necessary.

Weed Control

What are noxious weeds?

Noxious weeds are non-native plants that disrupt native vegetation because they have no natural controls and are able to adapt to varied climate conditions. Noxious weeds are an invasive plant, which are not native to our ecosystem – harming the environment, our economy and even our people.

Weed Control

What kinds of weeds are common in Colorado?

Common Colorado weeds include dandelion, bindweed, spurge, mallow, crabgrass, and foxtail. Swingle’s weed prevention products will help managed and control these weeds.

Weed Control

Does my lawn care program include weed control?

Yes. Our lawn care program includes pre-emergent weed control to prevent crabgrass and spurge.

Tree Service

Are your technicians certified?

Yes. Swingle is one of the few landscape organizations in Colorado to be certified OSHA compliant. In 1970, the Occupational Safety and Health Administration (OSHA) was created. The goal was to help create a safer work environment by working with businesses to establish standards that are workplace-specific. The rules and regulations developed ensure workers are in the safest environment possible as set forth by OSHA. Swingle spends more time on training hours and invests more money in industry related training than any other Colorado tree company.


Additionally, many of our lawn and tree care experts have gone through rigorous training and are certified through TCIA (Tree Care Industry Association) and ISA (International Society of Arboriculture).

Tree Service

What steps will be taken to ensure my property is not damaged?

When utilizing bucket trucks, cranes and other large vehicles on your property, Swingle will lay down protective coverings in order to make sure heavy tires will not damage your property. Potted plants, lights, patio furniture, and decorative yard art should be moved from around trees before crews arrive to perform the work. Additionally, we remove your tree in stages, starting at the very top, to lessen the chances of the tree falling onto your home or homes around you. We work directly with the power company to make sure that electrical and telecommunication lines are safely moved out of harm’s way.

Tree Service

How long will the tree removal process take?

While some companies will promise you quick tree removal service, Swingle prides itself on protecting its staff and your property. Therefore, we factor in properly preparing and protecting your property and inspecting the location for electrical and telecommunication lines before removing the tree in stages. An average size tree should be able to be removed in one day, but larger trees might require an additional service day or days.

Tree Service

When is the best time to schedule tree pruning?

The best time to prune trees is in the dormant season when tree growth is not active and removal is less stressful to the tree. Some species of tree must be pruned in dormancy. However, trees can be pruned throughout the year if necessary, as long as proper precautions are taken to ensure the least amount of damage is done to the tree.

Tree Service

Is having my trees pruned necessary?

Professional tree trimming is essential to healthy growth. Dying or dead branches, overgrowth and interference (when one tree grows around and/or through another), creates unhealthy conditions, making the tree less attractive and more susceptible to breakage.

Tree Service

Do new trees need to be fertilized?

Yes. Young trees require very different nutrients than older, more established trees. Swingle offers a three-stage fertilization process to protect young and new trees from the time they’re planted throughout their maturity. Our tree fertilization treatment is specifically formulated for trees in Colorado.

Tree Service

Does Swingle treat for emerald ash borer (EAB)? Does Swingle offer soil or trunk injections?

Yes. The insecticides we use to combat EAB are placed in the soil or injected directly into the trunk of the tree. We offer both soil and trunk injections depending on the size of the tree trunk and your proximity to a detection zone.


Will my company be able to afford Swingle?

We know that now – more than ever – affordability and a balanced budget are top of mind. So we are committed to working within your budget, offering economies of scale, prioritizing your property’s needed services and bringing you peace of mind.

The projected dates are Swingle’s way of informing the customer when they should expect services to be completed. Due to weather, and other unpredictable circumstances, it’s essentially impossible to give exact dates – months or even weeks in advance.


What is the prepay discount and when does it apply? Does it prioritize my service over others?

Swingle Lawn and Tree Care provides a 3% prepay discount to customers who want to pay for their services in advance. It’s taken at the time you approve and pay for services. Payment needs to be made in full to receive the 3% discount for those services. Any service that is not prepaid for at the time of authorization, does not qualify for this discount.

NOTE: Pre-payment has no influence on scheduling of services. Swingle services are scheduled in the order they are received departmentally. Pre-payment does not elevate your position on that schedule.
