This is my new experiment. Our acreage is studded with HUGE boulders and many mid size to small ones too. I have a few fig trees. I plan to take cuttings soon, dig a slant hole on the South side of a boulder, and let the dampness under the boulder encourage roots and water the tree. No irrigation ever. I have nothing to lose. These are cuttings from trees I own. Just would rather reap and share fruit with the birds, the coons, and whatever than look at tumbleweeds.

I edited this to say that figs do not like "wet feet." They love to be under rocks in that dampness, but their tops love sun.

Have any of you planted anything under a boulder to let the dampness provide the water it needs?
