Blueberry bush with one large trunk

I have several blueberry bushes and I largely ignored pruning them for several years. The time finally arrived and I pruned several of them last year. All but one had numerous canes of varying ages. However, one plant has a single large "trunk", bigger than my wrist. A foot or so up it splits into several branches. I pruned off a large, problematic branch last year and was rewarded with new growth in the vicinity of the cut, but not new canes coming up from the ground. How would I go about pruning this...tree?

Putting sulfur in hole with blueberry plant

I plan to plant some Star blueberry's tommorow, but my soil is 6.2 pH. My plan is to mix some sulfur with the dirt under the plant, then put some peat between the sulfur and plant, then after planting sprinkle more sulfur around plant and then cover with pine bark. Questions are: will this be safe for plant? How much to use? How long before I see a reduction in pH?
