I’ve been planting pine trees and my usual tomato garden at the beach, and decided it was time to investigate an easy hose-faucet-timer irrigation system.  My beach neighbor Tom suggested the Simple Soaker by LR Nelson.  Indeed, it doesn’t get any simpler.  The kit comes with 50 ft of hose and 5 sprinkler heads that sit on stakes that you push into the ground.  Screw the sprinkler head down, and it neatly punctures the hose. No muss, no fuss.  If you screw up the placement of your sprinkler heads, unscrew them, put a plug in the puncture (plugs included) and reposition the sprinkler head. It’s $29.13 with free shipping at Amazon.com.
