Recently, I planted a couple of fruit trees in my garden. I placed
large flat stones (like crazy paving, but without the mortar) around
the base to deter weeds from growing and drawing on the soil's
nutrients. Was this an OK thing to do? I keep the trees well watered,
using a hose. I ask because I can't remember seeing this method of
weed control used anywhere else.

They might sulk if it excludes oxygen from reaching the roots.
ISTR fruit trees can reach badly to being buried too deep.

Thank you. It did occur to me that the weight of the stones might compress
the soil unnaturally. I also wondered if it would have any effect on the
earthworm population around the roots.
