We have a large viburnum
Our plant is not flowering. It has always in the past but not this year. I don't think we are doing anything different. It looks healthy. Any ideas? Thank you.

Too much nitrogen-rich fertilizer can discourage viburnums from blooming. You can counteract this by adding more phosphorus, like bone meal, to the soil around your shrub to encourage more blooms.
