Minnesota Weather and Mulch

We have been getting lots of questions about what type of mulch to use in your garden beds, rock or a shredded wood.  Both are good to use in their own applications, but the plant type plays a more important part in picking the type of mulch.  For example if you have a sunny garden bed and use are planting perennials you would want to use a wood mulch, and here is why.  The rock on a sunny day gets hot under the sun as you well know, but when perennials are added you can stress out and at times even kill these plants by the intense heat.  The sun hits the plants from above and the rock bakes them from under, way to much stress.  A shredded wood be the perfect mulch for water retention and to not hold so much heat.
A rock mulch works better with shrubs and trees because of the age of the shrub or tree is a few years.  They can handle more of heat from the sun mixed in with the heat of the rocks.
