japanese red maple tree
The leaves have yellow spots on some of the leaves. What does it need to correct it? Thank you.
The most important thing is to learn what is causing the yellow spots, whether a disease, insect, or mineral imbalance. The simplest thing is to take leaf and soil samples to the nearest Extension Service office for analysis and recommendation.
