I have 4 viburnum bushes planted 2 years ago that have grown well. Have had no flowers and noticed last few months that new leaves are quite brittle and brown. They only get about 2 hours sun in summer. Can you help?

The browning could be from unsual temperature changes or a fungus. This could also be inhibiting the blooms. Typically, they need lots of sun for blooming too, but you can try adding some bone meal to the soil around your shrubs to help encourage flowering. Also, cut out the dead, brown foliage and treat it with a fungicide, like neem oil.
