I need to irrigate a small flowerbed which is about 20 feet from where my water source is. I know my options for getting water to the bed but I am thinking the least damaging at this point would be running the 1/4" tube. I don't want to dig up the lawn again to get 3/4" pvc pipe down there. I am thinking i can run the 1/4" brown tube real close to the soil and the grass will grow over it at least until i feel like digging up the grass again.

I am going to setup a dedicated zone to this bed which will run the tube. Will it work? Will I lose too much pressure? I am not worried about gophers or moles...just pressure....is it decent enough?
