All this time I've been wrong?????
I recently purchased a viburnum from a Master Gardener who has been in the nursery business forever. He gave me a handout which stated that every type of mulch I've ever used is tantamount to poisoning my plants. I've been using a high quality root mulch (not dyed) and with the exception of my flower beds things seem to do well. He states that the ONLY acceptable type is Southern Pine Bark which is like $55-60 a yard as opposed to the $20 per yard I use. We need about 60 yards every year so that's a huge difference. The place I get my mulch suggested that I upgrade to their organic peat mulch @ $36. per yard. I got 15 yards to see what it was like and it's obviously better but I'm inclined to use it only in my prime bedding areas. Any opinions?
