Azalea Flower Buds

Question

This spring, many of the flower buds on my azaleas turned brown from the center out and, of course, did not open. Some bushes have a dozen flowers, all near the ground, and some have none. One bush is blooming beautifully. Was it the cold snap after a warm period, or is some disease attacking the buds?

Answer 1

It could be either botrytis or thrips. These articles will help: https://www.gardeningknowhow.com/plant-problems/pests/insects/controlling-thrips.htm, https://www.gardeningknowhow.com/plant-problems/disease/treating-botrytis-blight.htm
