It's been terribly dry in our area resulting in a need to sprinkle the garden. I have been using a normal oscillating sprinkler, having to move it from here to there plus determine exactly how far "left", "right" or "center" I needed to set it. It would over sprinkle or under sprinkle. Now, I think we have found the perfect sprinkler for this area. It was $12.99 at Tractor Supply.
Since we fenced around the beds with T-posts, this model sits right on top of the post. It works just like the stake sprinklers, setting the area with the movable bars and the pressure by dialing up or down the nozzle. We can now reach both beds and we don't overshoot the area. I believe we will pick up another to take care of the more narrow lower beds. It looks like we will need to fence it a little too -- deer tracks plus our stinky visitor from last night! They haven't bothered the watermelon, zucchini or pumpkins for now but one never knows!
