Snowball Viburnum Not Blooming: Pruning Time and Fertilizer Balance

Why No Flowers

Wrong pruning time: Pruning after July removes next year's buds. Prune only late summer to early fall.
Excess nitrogen: Promotes leaves, not flowers. Use low-N, high P/K fertilizer.

Prune after flowering (late spring) to control size. Never after October.
