I am digging in the garden today with a 2 yr old great grandson, we have relocated at least 9 - 5 gal tubs of dirt today, forgive the exhaustion, but I meant the thread starter and changed the directive. Zoe you are in NM when the sand dries out and a cloud bursting gully washer comes thru, the water doesn't penetrate the sand, because the particles repulse moisture. Works on small pots and under Cumulo Nimbus towering cloud bursts exactly the same.
