Root watering

I’m working on an irrigation system for my ~20 fruit trees, and I was wondering what everyone thought about root watering. My searches turned up empty.

I’ve seen the section of PVC trick all the way up to the Rainbird RWS (root watering system). Does it work better than just plain old drip irrigation?

I have dense clay soil, so I’m not sure if that makes the idea more or less effective.


No one? I guess that doesn’t speak highly of the product.

I noticed all the sidewalk trees put in by the city have two of these root-waterers installed.
