Hi,

I just came home from a weekend away and noticed that my Hydrangea tree is sprinkled with yellow or yellow/brown leaves. The leaves that are green look healthy, but the ones that are yellow are starting to show brown speckles. On Friday I gave it a good watering because we needed the rain and I didn't know if we'd get rain before I came home. Are the yellow leaves a result of one day's overwatering, or a slower more subtle result of a long time without rain? The tree is only a few years old and is maybe 6' tall. It's got lots of blooms ready to burst, but I am worried that the leaves will continue to yellow and fall off. Soon I'll have a naked tree with ivory blooms. Should I go out now and water it some more, or leave it alone? It's that age-old question - did I over-water or underwater? Can one over-watering make a difference?

Thanks,

Michelle
