Answer: There is a good possibility that pH is in fact the cause for this. Pansies prefer a more alkaline growing range of 6.5 to 7.0 and snapdragons from 6.0 to 7.5. You might also find that there is some other imbalance in the soil if you test it. You might wish to confer with your County Extension (836-4204) about testing your soil and any possible amendments especially if you plan on extensive use of this mulch.
