I'm pouring a driveway and will have excess dirt. I am in Phoenix, AZ. I need a place to put it and the thought is to build a larger 3-4ft mound for desert plants to grow on top off and on the side off.
I am also trying to make use of scrap pavers that can't be reused. I have a lot of cut offs from a patio project, smaller ones that provide little purpose. I thought I may build a base with these and bury it in the dirt.
The mound will have native species, saguaro, agave, ocotillo, etc.
If I make a pile of pavers, dump the dirt over the top via excavator, slight amendments to break down the clay. Do you see any issues in doing this? I'm not sure it helps with drainage as soil is caliche, but with some amendment maybe? I think the cacti will still grow, but any ideas to make it drain efficiently?
