we have a plant that comes in every winter and back out on the porch every summer. i do spray it when it comes in and it is on a different floor than other things growing. It is advised that grows not be subject to house plants, just as a matter of safety....just sayin
+1, we put a couple plants outside every year and bring em back in for winter. They do get sprayed and kept separate from my indoor garden tho.
Most recent hitchhikers were a petunia and a cottonwood sapling! I'll probably pull the cottonwood, we have no need for a potted tree.
