Get matched with top mulch and topsoil pros in Coon Rapids, IA

The number of bags of topsoil you need depends on the depth you’re filling. The average topsoil is sold in a roughly forty-pound bag, covering 12 square feet at a one-inch depth. Since topsoil is by nature the uppermost layer of soil, you can bet on only needing to fill about 4 to 8 inches of soil depth with it.

While they’re popular and have a lot of pros, the cons of river rocks include the following:

• River rocks don’t break down or provide nutrients to plants. 

• These stones can get hot and scorch nearby plants. 

• River stones may heat the surrounding soil to inhospitable temperatures. 

• Rocks can block rainwater from seeping into the ground if installations are too thick or tightly packed.

Most downsides occur when using river rock as mulch in gardens and flower beds. However, you can still incorporate river rocks into your landscape as long as you use them in the correct ways.

Timing is key when determining the best time to hydroseed your lawn. It’s best to hydroseed in the spring or fall due to the already wet conditions of your lawn and the more mild temperatures. 

Your local pro will also offer watering and fertilizer instructions for the months after your application. Make sure you will be available to water it consistently, especially in the first two to three weeks for best results.

A 40-pound bag of topsoil covers 0.76 cubic feet, enough for 4.5 square feet with a 2-inch depth or 36 square feet with a .25-inch depth, such as topdressing a standard garden bed. If you want 2 inches of fresh topsoil for your 36-square-foot garden bed, you’ll need eight 40-pound bags.
