As everybody know, we have the worst summer in Texas since 50 years. Every plant is stressed. We have a hedge of 10 Leyland Cypresses , they are meanwhile around 7 feet high but start getting brownish at some parts of the tree. I'm reading different suggestions about watering now. Some gardener experts say ,only water once a week, even in a drought and others say keep it even moist. I'm aware of standing water or overwatering that this will cause problems. We just have given them new mulch and we laid out a soaker hose, but we are just not sure , if we are supposed to use it every day and for how many minutes/hours? I'd be grateful about every hint you could give me!

Thank you!
