Growing roses in a gravel covered bed
We are buying a house, and there are is one bed the previous owners used rock/gravel as basically the mulch. If I dug down and planted my roses in this bed, would the rocks make it too hot for the roses? They will get morning sun but shaded in the afternoon.
The question I guess is basically, do we need to remove the rocks, leave them, or just cover them with mulch?
Thanks for the help!
