Q.Why are the edges of leaves on my Popcorm Viburnum turning brown and crispy?
I planted this popcorn viburnum bush earlier this spring. I live in zone 5. It is in a location where it receives 6-8 hours of direct sun daily. At first, it was doing quite well but lately the leaves are turning brown and crispy all along the edges as if they are burnt. I water this shrub deeply about every third day. What can I do to save this shrub?

It is possible that there are air pockets in the soil that are affecting the roots. I would step firmly on the root balls to help collapse any air pockets. Flood the area with water to help fill them in. Up its watering as well. It may also have a fungus disease, so I would treat the plant with a fungicide.
