I live in Fairfield, California, Western Garden Zone 14. I am having a
hard time figuring how much I should water my plants. My drip system is
fairly accurate; so if I know the number of gallons per week (during peak
watering time) for my plants, I should be able to get it right.

I have been told that a "small shrub" should get about 10 gallons per
week, but I don't know whether that applies here or not. Is there any place
that I can get better information?

I would like this information for specific plants as well, if possible.
Some of the plants I have a Hydrangeas, Persimmon tree, Crape Myrtle
trees, Lemon tree, Jade plants, Cymbidiums, Roses.
