Drip Line: Bury or not to Bury (very long run).
OK! So I need to run a Drip line to some very Drought hearty Trees and shrubs along 1,000 feet of property line. This is provide occasional deep watering to Acacias, Melalueca's, Pines and other mature trees and shrubs.
I think I'm going to go with a large drip line with inline emmiters every 18" inches or more.
Neighbors tell me that rats eat holes in drip lines here occasionally. My question is this: Should I bury these lines under a heavy layer or wood mulch? Or does this just make it really hard to find leaks when they occur and perhaps its better to run it right on top of the ground for ease of inspection and troubleshooting. What should I do?
