Why are my leaves turning yellow and falling off?
Poor drainage or improper watering
Water issues — either too much or too little — are the leading reason behind yellow leaves. In overly wet soil, roots can’t breathe. They suffocate, shut down and stop delivering the water and nutrients plants need. Underwatering, or drought, has a similar effect.
Will Overwatered yellow leaves turn green again?
When the leaf loses its chlorophyll, the plant abandons it and begins to absorb leftover nutrients from the leaf. That’s why once the leaf turns yellow, you generally can’t make it turn back green again. (Although in cases of nutrient deficiencies, sometimes yellow leaf color can green back up again with treatment.)
Can green beans be overwatered?
Watering. Keep both bush and pole beans well watered, but be careful, as beans tend to rot in the ground if over-watered. To avoid this, allow the top layer of soil to dry in between watering your starts.
