|My snowball viburnum is about 3 1/2 to 4 foot tall and it has never bloomed. Do I need a special soil or acid something to make it bloom or do I need to have a pair of them. I am in zone 7. Thanks|
You don't need a pair for a plant to bloom. The reason for a lack of blooms may be that the plant needs more light. It can take partial sun but not too much shade. It also prefers an area with summers that are a little milder than yours. You are in heat zone 9 and it is rated for up to only heat zone 8. The stress from heat may be part of the problem.
Thanks for the question. Please stop in again soon!
