Q.I Planted 3 Arrowwood Viburnum Shrubs In Early Summer, Spaced About 6 Ft Apart. One Has A Lot Of New Growth (about 10 New Shoots)
while the other two look healthy but have no new growth. Should I be concerned or do anything about this? I water and feed them all equally. They get morning sun. The only difference I can think of is that the one with new growth may get more water from my sprinklers, but I don’t run them often. I usually water the shrubs manually when there isn’t any rain or if it’s very hot outside.
I should have mentioned that my soil has a lot of clay. Now that I think about it, the one with the new growth probably does get a bit more sun. Could it possibly be a male/female plant issue? I read that I should plant more than one shrub if I want to get a lot of flowers and berries, but I didn't think that they're specifically male or female, like holly or sumac.
