Help needed with my Viburnum plant
I hope to get your advice about a Blue Muffin Viburnum that I planted in my backyard about 5 years ago. I live in Brooklyn, NY. This is the only viburnum growing in my garden. And it is receiving southern exposure light, so it receives lots of sun.
Here are my two problems:
1) In the first 2 years, it produced lots of beautiful white flowers that turned into little unripened green berries but which never reached its maturity. I would see the unripened berries for a few days, and then the next day, most would disappear and whatever remained seemed to have broken off. We get many sparrows and a few mockingbirds visiting our garden. Perhaps the birds are responsible…I can’t be sure because I have never caught any of them eating the berries.
2) For the past 3 years, the viburnum did not produce any flowers, just lush green leaves and lots of them. This past spring, it produced not more than 4 clusters of flowers which then turned to unripened tiny green berries that eventually disappeared.
I am befuddled about this and would sure appreciate any advice you can give. I am so disappointed that my viburnum has never reached its full potential and hope there is some solution to rectify this problem.
