Hi, I'm not real sure about this mold where you live, but we have mold on our cherry trees, and if I spray them with garden sulphur it usually cures it. The mould on the pine while it is curing, is usually a sign of not enough air circulation. The bleach and water solution works for me, plus get some more heat and air circulation around it. I tried drying pine boards in my basement, thought it was a great idea. Stuck it and piled it correctly. Well in the spring it was a mess of mould. It needs light, and air circulation, plus some heat if there is any. The best place for me to dry wood, is overhead in a building. Nothing gospel in my information, just my two cents worth. Hope it is some help. :
