I've purchased a 5gallon rhododendron about 2 years back (forgot the name now but searched high and low for that specific species..flower is supposed to be white in the center and hot pink on the edge) and planted at the side of the house under a willow tree so it gets plenty of shade. The plant is very healthy except it doesn't flower!!! For 2 consecutive years, it produces the buds but will blossom into leaves instead of flower. I've reasoned that it was adjusting on the first year but cannot excuse it this year. Did I neglect to supplement it during planting? I used supersoil potting mix and/or steer manure. We're in San Jose, CA (I think that's zone 9a?) and we get plenty of clay soil here.
Thanks in advance for your input.
