We have a 2 year old dogwood and has been doing great but I see where a few of the leaves have turned yellow and have sort of brown spots on them. I water twice a week for it has been dry and hot. We live in Southern Indiana but I wonder what am I doing to cause this? It is planted at the NE corner of our house, gets some sun in the morning but not the hottest of the sun during the day. It sort of sits at the NE corner of our house underneath the overhang. What would cause this?
This could be watering issues; too much or too little, pests, disease or nutrient issues.
