I read in many places that pine bark is light and heavy rain will wash out the mulch. Can I use two layers? First layer of Pine bark which and second layer on the top of Cedar mulch. So the pine bark will decompose and provide nutrition to the soil and top Cedar layer will protect the mulch and keep it in place.
Most folks will use one kind of mulch or another, depending on the plants and how frequently you will want to reapply or replace, however you could potentially cover pine bark with cedar. Pine Bark mulch will decompose more quickly and be reapplied as needed. Cedar mulch decomposes more slowly, but when reapplying you will want to remove the old mulch and then apply fresh mulch in its place. If you have young, tender plants, then cedar mulch may damage them.
