Great idea -simple but I think roots would grow to the holes and block
them
unless pipe is on top of the gound-paint green and you won't see the
pipes.alternatively put stocking or fine mesh over outside before burying
but will prob rot.

Thanks Stan,

I guess a simpler idea would be to use the "aggi" pipe instead of the PVC.
Its a flexible, black plastic perforated tubing. Its got more holes in it
and might solve the problem you mentioned.
