I think you misunderstood. I don't water once a week. I water all day every day, but each section gets watered only once a week. I have seven hoses, by a happy coincidence, so I've assigned a day of the week to each. Watering each of those seven sections is pretty much a full-time job with no days off.
I worry about my trees because I'm concentrating on watering each flowering plant and ignoring the spaces without them.
I wish I could plant 200 irises. I used to have hundreds and hundreds of them here, but after I enclosed all of the roses in gopher-proof cages, the gophers went after the irises, which are dwindling at an alarming rate.
