pruned at the wrong time
Hi, My husband accidentally pruned our viburnums -- one snowball, one with tiny white flowers-- at the wrong time last year. This spring, they did not have any flowers except for a couple at the bottom of the plant where he didn't prune. I am wondering if we should prune the new flowerless green growth back this spring, or should we leave it til next year? Thank you,
If the plant is the size and shape you want, you don't need to prune again. Those flower-less branches should bloom next year.
In general, the best time to prune blooming shrubs is just after they have bloomed.
