Woodway is large, wooded lots and a town of 1,384 people. The canopy is the landscape. Lawns live in the gaps between old trees, the soil stays shaded and cool, and privacy is the reason people bought the property. No farm grows sod for the floor of a cedar grove. Laid there, it thins, mosses, and you have paid for a temporary green.

Sod is the wrong product in deep shade
We will sod the open part of a wooded lot, the piece that gets real afternoon or morning light. Under the canopy we stop and talk about bark, ferns, and a smaller lawn. That is cheaper over three years than replacing sod.
Where light is marginal, we say so in the bid. If you still want sod, we prepare the soil and we tell you it is a shorter life. We do not pretend otherwise to win the job.
The ground in Woodway
We are not opening these lots to the street. Pruning is about structure, light, and keeping limbs off the house, done so the screen of trees stays. Under that canopy the lawn is the hard part: moss, thin grass, and roots at the surface. Aeration helps the pockets that get some sun. The deep shade wants a different floor — bark, ferns, and the understory that is already trying to grow — not another season of seed that germinates and dies.
Hardscape, when it belongs, is a terrace or a quiet patio in a clearing, built for wet shade so it does not turn green and slick. Bark on the beds keeps the mud down and the edges readable from the house. The work should look like it was always in the trees, because it is.
How we do the work
Sod is instant cover and a slow root. It dies when it is laid on compacted clay, on a moss mat, or in a low spot that stays wet. We strip or till, we fix the grade so water leaves, and we lay tight seams on soil that has been loosened a few inches down.
The first two weeks are water and no traffic. After that we want roots chasing soil, which means less frequent watering. A sod lawn that is sprinkled every day forever is a sod lawn that peels up in August.
We lay what arrives that day. Sod that sits on the pallet through a warm afternoon cooks in the roll, and we will not install it.
What we look at first
- What is under the old lawn
- Grade and where the roof water goes
- Access for the pallets
- Sun, because sod in deep shade is an expensive way to grow moss
The first two weeks
Water enough that you cannot peel a corner up by the end of week two. Stay off it. Mow the first time at three inches once it resists a tug. Then ease the water back so the roots leave the roll.
When seed is the better buy
Large areas, deep shade, and tight budgets that would force us to skip prep. Seed costs less and roots deeper if you can wait a month. Sod is for the yard you need to use, on soil we were allowed to prepare.
What is under the roll
A few inches of loosened soil and compost, graded to leave the house. Not the old lawn. Not landscape fabric. Not a sand bed that turns into a pan. If we cannot prep, we should not lay sod.
