I had a rubber plant that was infested with what looked like tiny red
spider mites. It was potted in a clay pot.
I've since thrown away the plant and soil, but wonder what I need to
do to properly clean out the pot so that there are no stragglers. So
far I've just washed the pot with water, but want to make sure that
the its next resident doesn't become host to a spidery-family.
Should I be using a soapy solution? Something else?
Thanks in advance!
