It isn't unusual for a recently planted rhododendron to skip a season or two of producing flower buds while becoming established in your garden - this tendency will vary somewhat according to variety. It could be establishing roots and framework in lieu of flowers...

Other reasons for failure to bloom are too much shade, over fertilization, and drought in late summer when buds are normally set. Also pruning at wrong time of year, but I suspect you haven't pruned such a young shrub :)

Thanks for you response. It's the typical purple rhododendron...don't remember the variety. No I havent pruned it or fertilized it. It's possible it wasnt watered enough end of last summer...but youre probably right, it's probably establishing roots. I'll patiently wait another year with fingers crossed!

Is it getting enough sun?

my Azaleas were beautiful as usual except one. It has bloomed for years but suddenly this spring and last no blooms? It appears healthy , it is growing around four others that bloomed beautiful, Any one have any advice? Thank you

Sometimes the trees around azaleas grow to the point that the light decreases.
