Answer: Your rhododendrons are certainly mature enough to bloom! They are probably not getting the correct amount of sunshine - and that amount varies, depending upon the cultivar. In general, they should get a few, up to 4 hours of morning sunshine but be shaded from afternoon sunshine. You may need to move your rhodies before they will be happy enough to bloom. Pruning is another consideration. Rhodies develop flower buds all summer long for their spring floral display. If you are pruning your rhodies in summer, you may be pruning off the following year's bloom. Try pruning after their normal bloom time (usually mid to late May) so they have time to develop flower buds. Hope this information helps!
