CLEANING TERRA-COTTA POTS
Terra-cotta pots need to be properly cared for so they’ll do their job well the next year. Before storing, disinfect pots to rid them of moss and soil residue that may carry diseases harmful to new plantings, especially to vulnerable seedlings. First, soak the pots in a sink, bucket, or bowl filled with a solution of one part bleach to ten parts water. Then scrub them inside and out with a scouring pad or bristle brush (we used a bottle-cleaning brush). To prevent buildup of dangerous and unwanted mold, let pots dry completely before stacking and storing.
