I planted 2 Kousa Dogwood trees in the spring and they had been beautiful, but now that the weather is hot, they are dying. The leaves are turning brown and falling. I am watering them and the soil does feel wet. Could I be watering too much? I do not see bugs on them. We used mushroom compost to mix with topsoil when planting.

How long are you watering them for? The problem may be that you are not watering deep enough to really get down to the roots. If you are watering the soil for less than 10 minutes, I would leave the water on at a medium pace for at least 10 minutes. Water like this about 1-2 times a week. You need the water to get all the way down to the lower roots.
