I have a mulch job coming up with a total of 600 square feet of beds. 4 different beds, 2 are just open areas and 2 are foundation beds with shrubs. Someone put down that hideous red mulch some time ago. Person wants new mulch installed because they don't like the red. It's not very thick, maybe 2 inches and you can see bare ground in some areas. Would you rake all the red mulch out onto a tarp and make many trips and dump on the property in a back wooded area, or, just mulch over it? I feel removing it is the best way to do it but I wanted to see if I was just being anal retentive and mulching over it would be acceptable.
