Viburnum fruit set
I would be curious about other people's experience regarding how many viburnums of a given species you need to have them set berries. I have read/heard contradictory things. I recently planted 1 arrowwood, 2 cranberrybush, and 2 blackhaw. All quite small right now, so it will be a while before I see the answer for myself.
Will I need to plant one or more additional arrowwoods in order to get fruit set?
