Hello everyone, I moved to Phoenix about 7 years ago and was sucked into the xeroscape gardening and now I would like to transform this into a food forest . I live on a very small lot and have tons of landscape rock that I put in myself because that was what I thought was the right thing to do. It was suggested to experiment and remove the rock in some places and sheet mulch and then sheet mulch directly over the rock in other areas. . In the rocky areas I would just remove a small area to plant trees but leave the remaining rock surrounding it . I am trying to see if avoiding the removal of the rock and planting over it would work. I was curious if anyone has tried this before and which was was more successful ?

I would remove the rocks and use them to make berms or other landscape features. I tried gardening on top of rocks and it failed miserably. Digging them out is hard, but worth it, in my personal experience!

Not sure how many or how large your rocks are. Here we have rocks of all sizes some as big as houses some you can use in a slingshot. We move, split,pile, push and sell them. Move the rocks if nessary the earth likes grooming, likes to feel your fingers,water and your plants.

If your land has a slope to it, you could move the rocks from the uphill side to the lower side. Half circles on the lower side of trees, shrubs and beds could greatly help storing the scarce rainfall you receive.

I don't think you need to remove all the rock. rock mulch can moderate temperatures relatively well. thicker layers of rocks and piles can provide some water to plants through condensation on the interior cold rocks. piles can also be good for critter habitat. you'll have to move the rocks to dig holes for planting, but you can put it back afterward.
I'm definitely with yukkuri kame, though: definitely don't sheet mulch over the top or otherwise bury the rocks.
and more specifics about the rock in question would help us help you.
