Blueberries

What I know now. Plant them no deeper than half the root ball into the joyful Oregon clay soil (or they'll drown) and mound up a mix of soil, manure and fir sawdust (or shavings). The manure will add nitrogen to help with the breakdown of the fir (Douglas fir is the most readily available) and thus increase the acidity of the soil (lower the pH). If you can, incorporate fir sawdust into the soil the year prior to planting. If you can't then add a fertilizer high in sulfur (or add elemental sulfur). Either way Blueberries like slightly acidic dirt and just barely damp toes. Also, pluck off any berries for the the first couple of years otherwise the bush could become stunted and low-producing.
