We have a pine tree next to our deck 30ft off the ground. lately I've noticed a yellow sulfur poder on the leafs we clean them by washing or brushing them litely. Can this hurt them-the Girls or change soil-PH? Any info please Thanks Blissed
I have the same thing going on. It turned out to be pollen from a giant protocarpus growing about 6 feet away. it's all over my corn, orange tree and the weed.
