Viburnum flower buds not opening
I have a viburnum bodnantense dawn that has flower buds all along its branches but they don't seem to want to open. Only 2-3 have dared to open but even they seem a little tentative! This is only the 2nd year I've had this plant. It's in a pot & sits on a north facing balcony & only gets sun in the morning. I haven't noticed any bugs or pests.
Am I just being impatient (the buds have formed for at least a month now) & they will open eventually or is there something I should be doing to help them along a bit? Eg does it need feeding?
Be grateful for any tips. Thanks
