We live in Queen Creek.  We planted three chinese evergreen elms in April, and they don't seem to be thriving.  I have been watering them for one hour every three days.  Someone once told me that if the leaves on a tree or plant turn yellow before they turn brown, that means they are overwatered.  Can you please tell me what to look for to know if I am under- or over-watering the trees?  How often/long should I water?  (p.s. we ran dripper lines to the tres).

Thanks
