Top Soil in Anchorage

What Is Topsoil?

Topsoil is often a loosely-used term. In the landscaping industry, when we refer to topsoil, we mean blended and screened materials that are combined together to formulate topsoil that is within the municipally-specified topsoil mix.

"Muni spec" topsoil is:

Peat moss (organics)

Loam (silt)

Sand

These elements are all in appropriate portions to compose the specified topsoil.

Here in Anchorage, we are fortunate enough to have a large enough supply of peat moss to use it as the base of our topsoil product.

Peat moss is decomposed organic matter that has a PH that is preferably about 7.5. The loam and sand are added to provide drainage and the ability to become somewhat firm, but allow roots to freely spread as deep as needed to gather as much nutrients from the soil as possible.

The Quality of Our Topsoil

We have several grades of topsoil available. Depending on your need and end use, we'll help you choose which grade to select.

For class B topsoil, we use a 1" screen. We use a smaller (1/2" screen) for lawns that will be walked on, mowed, etc., since you would not want big stones or sticks in your lawn.

In bedding it's not an issue, as there is more than likely a topping of weed fabric and stone or bark mulch over the soil. So for deep planting beds for trees and shrubs, we can usually cut your cost by using a large opening on the screen we use for sifting stones and sticks from the process.

Another process that's becoming very common is blending compost into topsoil blends. We make our compost from wood chips we get from the tree felling part of our operation and lawn and leaf debris from our grounds maintenance division. We roll the piles periodically to infiltrate air into the composting material.

We also use red wiggler worms to aid in the composting process. When the final product is screened, the result is a finely graded, nutrient rich, PH-balanced compost that's excellent when added into our topsoil blend.

More about Our Topsoil Process

Topsoil will be installed at a depth of 3-4” after compaction. 

The soil will be sacrificed to receive hydroseeding with maximum result.

The seed application rate will be approx 7 LBS per 1000sf. This is nearly 3x the recommended minimum application rate.

Starter fertilizer will be added to the hydroseed slurry.

We use a combination of wood cellulose fiber mulch and virgin wood fiber mulch. The combination of mulches is a great water retention agent and aids significantly in erosion control on 3:1 slopes or less.
