cherry tree

Question

Tree looks as if it’s dying. Leaves have not been a good green all summer, and have noticed holes in leaves. Keep watering but no different, flowers were white instead of pink. Could you tell me what trouble is, please?

Answer 1

This could be a nutrient deficiency. Leaves that don't fully turn green are often a sign of this. Here are some possibilities:
