1. Approx. how much water (in gallons) should I use in watering hydrangeas as a function of size? I have two quick fire hydrangeas and one climbing hydrangea (schizophragma moonlight variety). I planted about 2 months ago in partial shade, and was told to water 2-3x/week. I would guess the soil drainage is fairly normal.
2. How can I tell if I am over-watering or under-watering by looking at the plant?
Thanks.

You can start with 1 gallon of water per watering. It is best to determine if you are under/over watering by looking at the soil as there could be many reasons that make a shrub respond in the same way.
To see if the soil need moisture, insert a finger into the soil to a depth of 4" or so and water when the soil feels dry or almost dry. Always water the soil and not the leaves because watering the leaves often can result in powdery mildew infections. Water early in the mornings and maintain 3-4" of organic mulch so the moisture does not easily evaporate. Apply the mulch thru the drip line or further if the location is windy.
