Over-watering

Over-watering container plants is surprisingly common. According to the University of California, improper irrigation is the #1 cause of plant problems.


Unfortunately, the signs of too much water look an awful lot like the signs for not enough water: yellowing, wilted leaves, stunted growth, and leaf drop are just a few of the signs for both problems.


Rather than drowning your plants, allow the soil to dry out between waterings. Don't guess! Physically look at the soil at root level to check on the roots' living conditions. An inexpensive moisture meter can be purchased at any garden supply store.


As critical as water is for good plant health, this is not a time to assume your plants are getting the water you give them. Soil structure can move water away from roots. When plants show water stress symptoms, dig down next to the root system to make sure the water is going where it is needed.
