Viburnum Shrubs
Q.

My viburnum minus leaves and flowers have turned brown, dry and wilted.

Could it be cause by a disease or fertiliser burn because I spread about a handful of Growmore granules around the roots in early March.

I'm not able to enlarge this image and can't really get a good look at the plant or any detail on the leaves.

Yes, over fertilizing a plant certainly can lead to burns or plant die off.
Leaf fungus issues or bacterial disease can also be an issue with a plant in the description you give. Clean up any dead plant material around the plant and dispose of.
Avoid overhead watering.
