- Look for tiny buds forming at the tips of the branches.
Likely causes
Inadequate Light
Most likelyHow to tell: The plant is growing but shows no signs of bud development. It is likely in a spot with partial shade instead of full sun.
What to do: Transplant the shrub to a spot with full, unobstructed sun. It needs the intensity of direct light to trigger its blooming cycle.
Improper Pruning
PossibleHow to tell: You pruned the plant in late spring or summer, removing the growth that would have produced flowers. The plant looks healthy but lacks buds.
What to do: Wait until late winter or early spring to prune. This ensures you do not cut off the developing flower buds before they have a chance to open.
