Folks are always asking what types of mulch we carry. These are the two mulches we stock in bulk and sell by the cubic yard:
Double Shredded Hardwood Mulch
Our favorite mulch. This is a fine textured, uniform, naturally dark brown mulch derived from the bark of hardwood trees (very little woody material is included). It is from a Michigan source. It is particularly nice for working in beds with smaller plants such as perennials and bulbs, and composts into the soil over the course of 2-3 years, feeding the plants as it does so.
This is our coarser, more economical utility mulch. It is less uniform in particle size than our Shredded Bark, and has a lighter coloration due to the higher percentage of woody material. It is a by-product of local arborculture activities. We age our Woodchip Mulch for 6-12 months to ensure that it is far less likely to rob garden soils of nitrogen — a nutrient vital to plant growth. Woodchips typically last about three years in the landscape. Once groomed (to remove twigs) it is ideal for pathways, under play structures, and in beds where the aesthetic value is less primary.
Recommend Mulch Depth
With either material we recommend maintaining a three inch layer of mulch to ensure an adequate weed barrier, as well as conserve soil moisture, regulate soil temperature, and provide a groomed look for your landscape.For purposes of calculating how much mulch you need, keep in mind that one cubic yard of mulch covers a hundred square foot area (10′ x10′ or equivalent) to a 2-3″ depth.
