Rhododendron - Lime haters?
 

I would love to grow a Rhododendron sinogrande but my soil PH is around 6.5 (about the same as rainwater). The RHS recommend a soil ph for Rhododendron of between 4.5 and 5.5. Does it really matter that much?

For best results, yes. You can mulch with peat moss to help keep a
low pH.

Or use an acid-type fertilizer. It's also good on azaleas, hollys, and
various other evergreens.
