Seattle Lawn Care Programs

Our experience has taught us to offer natural and traditional programs, as well as basic, premier, or custom lawn maintenance options, allowing us to cater specifically to your individual needs. There is no need to sign up for a program if it isn't necessary, our experts will do a thorough analysis of your yard and recommend services tailored to your specific issues. Our lawn care programs include:

  • Natural Lawn ProgramOur organic lawn care services only use products that are certified organic by the Washington State Department of Agriculture. This program entails 6 fertilizer applications and 1 lime application which will help balance the lawn’s PH.
  • Traditional Lawn ProgramWe also offer non-organic fertilizer choices for your yard, weeds, and moss. Choose between our premier or basic program, or develop a program specific to your needs. Custom programs can include 4-7 applications each year.
  • Basic Lawn Program: The basic program provides you with 5 applications per year. Around Oct-Dec we will apply fertilizer and moss control. Jan-Feb we will apply a granular lime application. Feb-March we will reapply the fertilizer and moss control applications. Finally, around Apr-Oct we will apply 2 separate applications of liquid weed & feed or a granular fertilizer. 
  • Premier Lawn ProgramOur premier program follows the same application time frame as our basic program, however around Apr-Oct we will apply 4 applications as opposed to 2 in the basic. The premier lawn program provides you with 7 applications per year.

Lawn Aeration

lawn-aeration.jpgCore aeration is a method used to remove thatching in yards. Thatch is simply the layer of decomposing grass, debris, and roots found between the soil and the grass. A modest level of thatch is important for healthy yards, however if the yard becomes overrun with thatch then it becomes a hotbed for weeds, grass-eating bugs, and lawn diseases.

To prevent too much thatch from developing we use core aeration machines that produce breathing holes in the soil by removing chunks of grass, thatch, and soil.

lawn-fertilization.jpgEven though the Seattle area is lush and provided with plenty of rainfall, the soil may not have enough essential nutrients necessary for optimal growth. Plants, shrubs, trees, and your grass are all competing for the limited nutrients in the soil, and because of this it is recommended to add additional nutrients to help them grow healthier, and fuller. Washington Tree & Lawn Care provides scheduled fertilization applications based upon the requirements of the yard deemed necessary by our expert analysis.

Weed Control

boise-weed-control.jpgAll lawns have varying amounts of weeds that need to be controlled. Even if you think your yard is weed free, those pesky guys find a way to come back to life. Besides simply looking unpleasant, weeds steal essential nutrients from the soil that could have been better fed to your grass, or other desired plants. We create custom weed control programs to remove these unwanted weeds, and guarantee approximately 85-95% control of the weeds in the landscape.

Moss Control

shutterstock_263044526.jpgBecause moss sometimes takes over the grass, or finds itself clinging to unwanted structures, it can be important to control and remove it. In general, moss is a symptom of one or more of these instances: acidic soil, too much thatch, too much shade, too much or too little water. Let our experts analyse your lawn and determine the appropriate steps to eliminate the issue.

Lime Application

Soil has a tendency to become acidic, and it is sometimes necessary to spread a lime application a few times a year. The lime will neutralize the soil and raise the pH level, which in turn will provide a better growing environment for your grass. Our staff will test your lawn’s pH level and make recommendations as needed.

Crane Fly Control


As adults, the Crane Fly resembles a mosquito and is relatively harmless, however when they are in their larvae stage they can be very destructive to yards. A Crane Fly infestation can leave a yard with bald spots or yellow and thinned sections of grass due to their feeding habits. To avoid this damage it's best to apply insecticide in the Fall, killing them off before the larvae matures enough to feed off your lawn. This preventative maintenance can save both time and money in areas where Crane Flies are prevalent. 


Wetting Agents


It's possible for lawns to develop a hydrophobic or water repelling effect, especially during the hot and dry season. This outer waxy coating prevents water from penetrating the soil, thus eventually killing off the grass. For situations such as these it is recommended to apply a wetting agent which can break up the waxy coating and allow moisture to penetrate the soil.
