I just put in a drip system to water my roses(1yr old), my Italian Cypress' (newly planted, 3ft), my FanTex Ash (newly planted 6ft), and my Mexican Elder (1yr 4.5 ft). I've been looking everywhere, but I can't find out how much and how often I should be watering them. Right now I'm watering every other day my Elder (6 gallons), and each rose bush (2 gallons). I'm watering every day my FanTex ash 6gallons and the cypress 4 gallons. Does this sound right?
