My Grandmother is having problems keeping her flower bed watered. Right now she has a soaker hose strung along its length, but it is forgotten and the plants die. She wants me to help her set up something automatic, but I don;t know what sort of system would be best. Should I put a timer on the soaker hose? this would probably be easiest. Should I run pipe and setup a bubbler or drip system? Its about 4.5' wide and runs 70' then curves around the side of the house, narrows to 2' 8" and runs for 24'.
