If you are planning to install driplines to water your trees or brushes. Watch this video. You will thank me later. I have run driplines to water my fruit trees and some nozzles are above ground and some are buried. The buried ones get clogged up with dirt and roots while the above ground ones get destroyed by my weed wacker. I will show you how to protect your driplines from both of these problems. Also this will allow you to add fertilizer to your plants using the installed pvc pipe set up.
