setting up a grow site in the ground with no watering needed

[mary scholz]

i came across this youtube video that showed by burying all plant debris , brush, logs etc it created a under ground water holding place . i don't know how to link but copied the name/ title. i am using it on plants in the ground. worth watching

try to google    "hugelkultur - the ultimate raised garden beds"   on youtube. maybe someone can post the link for me.
