Gro-Bark® Canada Red SPM® is a beautiful mulch product that will help you maintain your landscapes in a safe and
natural way. Canada Red SPM® is now over 25 years old and it is still the number one choice of landscape professionals in Ontario. It is very consistent and always arrives at a job in a form that is easily spreadable. Unlike stringy fibrous mulches, once Canada Red SPM® is established at a 4” depth in a bed, it is easy to top up with just an inch or two in subsequent years because it flows so easily. Great aroma and colour makes Canada Red SPM® a great aesthetic choice as well.
Canada Red SPM® increases moisture retention and root zone cooling, which minimizes
frequent irrigation. The added benefits of adding organic matter to the soil together with the acidifying
properties of pine mulch make a perfect ground cover for gardens, planters and tree plantings.
Gro-Bark® Canada Red SPM® has proven weed suppression characteristics unlike any other. Compared to untreated
bare soil, Canada Red SPM® has the best weed control in areas where chemical control cannot be used. Compared
with other mulch types, weed suppression is 80% higher with Canada Red SPM®.*
