Do you have an excessive number of flowerpots kept from past purchases? If you often share plants with friends or garden club members, then you may have just the right number of flowerpots. But, if you don’t exchange plants with others, then you may have toppling stacks of pots.
Save the best and release the rest. Also, Do you have old potting soil that’s not in the best condition and could be spread through your garden or compost heap?
