Q.Leaf Spot/No Flowers on Mountain Laurel
I have several mountain laurels that lose their leaves in the spring with leaf spot. New growth appears and the bushes seem healthy, but no flowers or very few. I live in a community not far from the water. These bushes are quite old. Any suggestions? Thank you.

Here is a great link with growing and care information. Pruning and a light fertilizer may help refresh your shrubs.
