Q.

Why are leaves turning brown and curling?

Hello, All 3 of my Viburnum Cardinal Candy (Viburnum dilatatum 'Henneke') have many of the leaves turning brown from the outside edge going inward, curling and becoming crispy. Planted on 4-20-2018. Any help would be appreciated. Thanks, John

The type of drying that the photos show appears to be from desiccation/drying. That can be a result of water-deficit/drought-stress or fertilizer burn. High Nitrogen, high salt index chemical fertilizers can desiccate roots and therefore restrict uptake of water. The extremes of the leaf tips and leaf margins dry up first. If the condition is severe the drying can continue into wider scale leaf burn and die-back.

This link is for an article on viburnum leaf browning, for your general information. But I don't believe your plants are suffering from any of the fungal disorders indicated.
