Can rain water “overwater” your plants?
Answer:
It certainly can, if you have flooding, or even huge amounts of rain. Plants that are overwatered by rain (or too much watering) can suffer root rot or may even fall over because the roots can’t hold in the soil anymore.
Obviously, if you are overwatering, you can just stop, but when the water comes from storms or storm surges, that doesn’t work so well....
