The Q&A Archives: Overwatering plants

Question: How do I know if I am overwatering plants?

Answer: When soil is saturated for long periods of time, oxygen is driven out and roots can suffocate. This usually shows up in wilting or yellow foliage, and eventually stem collapse. All plants need adequate water and well-draining soils. Infrequent, deep soakings are better than frequent light waterings. If you're unsure, you can water as usual, then wait 2-3 days and dig down into the soil to see how moist it is. If it is still moist 1 1/2 to 2" below the soil surface, you can wait a few days before watering again. If the soil is dry 2" below the surface, it's time to water. Hope this answers your question!
