Answer: The acidic soil should not be a problem. You probably do have a redbud tree, the shrubby form is part of it's natural growth habit. They do take a while to flower, 4-5 years wouldn't shock me at all. You can help things along by fertilizing your redbud regularly. I would apply a layer of compost or composted cow manure about 1" thick (mulch style) at the base of the tree all the way out to the drip line. I would also try fertilizing with a "superphosphate", this is simply a fertilizer with a high phosphorous content such as a 5-20-10 (phosphorous is the second number).
