i have used the undyed cypress mulch before as wellI brought some cheap mulch before and the dye came off onto my goats turned me off of colored mulch.. From what I calculated, it’s 47-50 for a truckload of sand vs 35 or so bags at 3.50-4.50 each. So going to save a lot with the truckload. And I have to clear my walkway for the wheelbarrow but it shouldn’t be to bad. I’m still considering adding a lime base first and now I also may need to consider lining the bottom with another 2x4 for depth
