Pruning
Prune this shrub immediately after flowering.
Remove a full one-third of all stems, and also remove any water sprouts or suckers at ground level.
It’s best to grow these shrubs from cuttings.
Like most viburnums, doublefile is fairly easy to propagate by softwood cuttings.
Sprayneem oilon the plant to kill anyaphidsas soon as you spot them.
The leaf beetles are a more serious problem.
Control measures should target the larvae, not the adults.
The University of Florida Extension suggests biological control, recommending that predaceous insects prefer larvae and adult beetles.
Another issue for your viburnum not blooming could be because of the time of year it was trimmed.
Always prune right after the shrub has flowered.
Another cause for viburnum not producing blooms is the fertilizing of the lawn or surrounding areas.
Fertilize carefully around any areas that have these types of shrubs.
Usually, this happens when the plant is not sited in ideal conditions or it is under stress.
These typically can be prevented by not watering with overhead irrigation and keeping the leaves dry.
These shrubs can grow around 1 to 2 feet per year with proper care and maintenance.
