Client: My Ficus tree has begun to lose many leaves. That has happened in the past; then it turned out that we had watered it too much and almost killed it by drowning. But this time my wife said that she was sure she did not over-water it.
Question: Why is my ficus losing its leaves?
Answer: The chart shows the ficus is too dry.
Treatment: Water it.
Outcome: The client cautiously began watering it. It recovered and stopped losing leaves in a matter of days.
