    I have not used either..my concern is the same as Kiril's. The other concern,
    as with other buried devices is, "how do you know it's working?" I suppose
    you could mark a spot so you could check it with the Lincoln moisture probe.
    Call me old fashion, I prefer a "four poster"of spray zones around trees, at
    the drip line..you always know if it's working.:)

    I have used them and been happy with the results. It’s really pretty easy to tell if they are working...if you get the version with the high flow bubbler they fill pretty quickly to the top of the cylinder so you can see (and hear) that they are functioning (the lid/grate in installed at grade). I have not seen any issues with root intrusion so far…

    Neat..looked like a cool idea, in theory, glad someone's put it into service.

    Another thing I would be concerned about is water usage. Seems if it is on the same zone as turf, your potentially putting ALOT of water outside the effective root zone.
     
  7. Yeah I'm not real sold on those either. Here is a technique I've thought of but never tried. I'm assuming most tree watering is for establishment. Once established I feel the irrigation system will provide needed watering when established. What if you took 12" spaced netafim and before backfilling the ball circled the ball at different heights using stakes to hold it against the ball. Finish it off with two runs at the surface. Once established cut the netafim off at the source and replace with a bubbler or not run at all?
    GOOD IDEA OR BAD IDEA?

    Not too sure about that. Seems to me that might lead to the roots never leaving the root ball. Perhaps if you did a triangle from the surface down?

    I can draw a picture if that helps.
     
  9. I can visualize what you are saying. Don't know that I agree with roots not leaving ball. Root growth is genetic.

    Yes, but roots will only grow where there is water. You want to draw the roots away/down from the root ball/surface by using your water to lead them in the direction you want them to go. Course this is all moot when your talking trees in turf.
