St. Patrick’s Day celebrates the color green, and we want to help your yard look as green as your St. Patrick’s Day celebration. So which topsoil or topsoil mix is best for your garden?
At Washington Rock’s topsoil plant east of Tacoma, all of our topsoil is mined directly from virgin earth, so you can’t go wrong with one of our products.
Our Basic Topsoil is a screened sandy loam. If you look at the Soil Textural Triangle below, you can see how much sand, silt, and clay our sandy loam has compared to other topsoils.
Our 3-Way Topsoil is a blend of clean sandy loam and compost. It’s a great choice for flower beds, gardens, and new lawns. Our product meets the planting bed soil requirement for Post Construction Soil Quality required by Pierce, King, and Thurston counties.
Wanting to build a rain garden? Our Bioretention Soil Mix is just what you need. It’s a blend of 60% well-graded sand and 40% fine compost. It is free draining, and the compost helps retain moisture. The City of Seattle uses the same blend around retention ponds and in gardens on high-rise buildings.
If you’re looking for something hardier, try our Garden Mix. It’s a blend of 50% clean sandy loam and 50% organic yard waste compost. It’s an excellent choice for gardens and raised planter boxes. It drains well and provides lots of nutrients for plants and vegetables.
