I am in the process of starting a small garden (6'x9'). My current sprinkler system doesn't do a great job of covering the area where I have placed the garden, so I would like to tap off of my existing system to add a head dedicated for the garden.
How tall should I make the head for this garden? Should I place it several feet above the ground so that it is able to get over some of the taller plants, like tomatoes? Also, is it better to place one single head for the whole thing or a few heads with less pressure around the garden? Or is there some better method for automated watering of this garden? I would like to have most everything underground while having to perform minimal amounts of digging to get it underground.
