Core Aeration

Lawn AerationLawn aeration is oftentimes overlooked as a critical lawn maintenance service. However, in order to keep your lawn healthy and your grass green and manicured, it’s important to aerate your lawn. In order for lawns to maintain optimal health, yards should be aerated twice a year.  

Core aeration is a process that creates space in between the roots of grass for water, air and fertilizer to be absorbed by the soil. The soil underneath of a yard will become compacted over time because of grassroots. In order to alleviate compaction, small pieces of lawn are removed. This process is strategic and involves an expensive piece of machinery, called a lawn aerator.


Lawn FertilizationFertilizer acts like food for soil that’s underneath of grass, plants and shrubs. Without regular fertilization, the soil’s nutrients become depleted. In order for plants, trees, shrubs and grass to grow, the soil that encompasses them must be nutrient-rich.

We offer traditional and organic lawn fertilizer. Both options provide yards with the appropriate vitamins and minerals for optimal growth, including nitrogen, phosphorous, potassium to create proteins and sugars for energy and sulfur, calcium and magnesium to stay healthy. Our organic fertilizer is comprised of sea kelp, fish byproducts and chicken parts while our traditional fertilizer is comprised of raw minerals. Call us today at (206) 362-9100 or request a free estimate to request your organic fertilizer service for your yard and garden. 

Lime Application

Lime ApplicationGrass requires nutrient-rich soil to grow, but it also requires soil that has a balanced pH level. Each species of grass is different, but most grass types thrive in soil that has a pH balance between 6 and 7; anything above 7 is too alkaline and below 6 is too acidic. 

You might be wondering why you’ve fertilized your yard, and still your lawn looks unhealthy. This might be an indication that your soil is not balanced. We offer lime applications for yards that have too much alkalinity. 

If you notice that your lawn has uncontrollable weeds or moss, this could be an indication that your soil is too acidic. Call us at (206) 362-9100 to schedule your lime application, or request a free estimate for soil testing and revival.

Weed Control

Weed RemovalSeattle is known for our evergreen trees, abundance of water and green scenery. Unfortunately along with all of the perks, we also get more than our fair share of pesky weeds. It's hard to keep a lawn free from weeds. Luckily, our lawn care company has experts in weed control. We'll remove existing weeds and prevent new weeds from being able to grow. 

Moss Control

Moss ControlA lot of people don't know that moss is actually a plant. It grows extremely well in dark and damp places. The Pacific Northwest is a perfect geographic location for moss to grow. That's why shaded lawns in Seattle are oftentimes overrun by moss. But not to worry- we're adept at removing moss and making it stay away. For moss removal and control, call us at (206) 362-9100, or request a free estimate from our lawn care company. 

Lawn Pest Control

Slug ControlLawn pests are a nuisance; moles and voles create unsightly holes in grass, slugs and snails destroy plants and crane flies kill grass. Whatever the pest you're trying to rid your lawn of, we've got just the solution. Don't let pests destroy your well-manicured lawn; call us instead for speedy pest removal!
