Rhododendron That Won't Bloom
Several (approx 6) years ago we transplanted a rhododendron. When we did
so we cut it way back to basically the trunk. It has re established
itself well in its new location. However, it has not bloomed since the
move. This spring for the first time it does have one bloom bud on it.
Is there anything we can do to improve this situation? It has gotten
to about 4 ft tall and 4 feet in diameter with lots of healthy new growth
but only one bloom. Thanks for whatever advice you may offer. Annelle,
After cutting a Rhododendron back this severely, the key word is patience.
Rhododendrons tend to have a mind of their own when it comes to producing
bloom vs.foliage. They tend to grow in cycles, with leaf production one
year and bloom the next. Not only did you cut your plant back, you also
transplanted it at the same time, so for the first year or two, the plant
had to produce a new root system, adjust to a new environment, and
regrowing. I can only assume that when you replanted, you added peat moss
to the soil so the pH was within 5.0-6.5 and you have been feeding your
shrub with an appropriate Rhododendron
fertilizer. Since it has
produced a healthy crop of foliage in the past couple years, it is probably
getting itself ready for a great flower show. Feed it well again this spring,
and each month until August, and expect a pleasant surprise next spring!
