Need Organic Mulch? We Have You Covered!

All of Hansen’s mulch, including our dyed mulch, is 100% organic. It is made from the green waste we produce when pruning and taking down trees.

Bulk mulch is available for pick at our O’Fallon and Arnold Missouri locations Monday-Friday. Saturday pick-up has seasonal hours. Please call 636.379.1830 for current pick-up times.

Hansen’s organic mulch is also available locally at Kirkwood Material Supply and World Outdoor Emporium locations.

How Deep Should Mulch Be In Your Plant Beds and Around Trees?

Hansen’s recommends an overall mulch depth of 3″. This depth will provide adequate feeding and moisture control for trees and shrubs. Keep in mind mulch breaks down at a rate of approximately 1″ per year, making yearly applications necessary.

Deeper depths are generally reserved for playgrounds and natural pathways.

Problem. Gone. I had two willow trees that grew up big, beautiful and fast and then they quickly became diseased and died in less than a year. After my previous experience with cutting down and digging out my own dead tree that was only 5" in diameter, I said there is no way I'm even contemplating doing this for a 10 inch diameter Willow! I heard them advertise for a long time with glowing reviews on the Dave Glover show and so gave them a call. They had a quote to me within 24 hours after their estimator came out and looked at my two Willows. From the time I replied to the e-mail (I accept the proposal, please remove them!) to the time the two trees were gone and stumps ground out was only 2 days! The two gentlemen that arrived were very polite and careful with their work, ensuring the yard was only disturbed to the extent required. They ground out those gnarly roots and went down a foot or so, then back filled it with ground up matter and soil. They even put back our grandma's memorial stones in the area and in the same pattern they found them! Very reasonable pricing, incredibly fast service and excellent staff. I will be using Hansen's for all my future tree needs.read more

Hansen’s pruned three trees at my business location. All the trees were around the parking lot. They were very careful not to let any of the branches fall on my staff’s cars and they cleaned up beautifully. Would definitely hire them again.read more

Hansen's removed a huge pine tree from our front yard that was past saving, for a very reasonable price. They also cut out an overgrown bush in the backyard and hauled it off for free!read more

We have used Hansen's twice. The first time, we had to clean up woods behind our new house that were overgrown from the lot being unoccupied before our house was built. They provided excellent advice on what to cut down and what to keep, and the woods still look great seven years later. This morning they removed a tree from my front yard that never did well (builder installed), and again they did a great job and cleaned up after. I would definitely recommend them.read more
