not blooming rhododendron

My 'Cunningham White' Rhododendron I planted didn't bloom last summer--why? The summer before was in a pot was gorgeous.

There are a number of possible reasons your Rhododendron didn't bloom. It's most likely that the plant devoted energy to establing its root system in the new location and diverted energy away from flower bud production. Soon after a Rhododendron is finished blooming, it starts forming buds for the next year's blooms. If you pruned it more than a month after it bloomed, you may have pruned off the following year's blooms. When the weather is dry in late spring or summer, Rhododendrons won't produce as many blooms for the following year. To keep your Rhododendron happy, make sure it gets at least 3 hours of sunlight per day and mulch it with an organic mulch like shredded cypress or cedar.
