When frost threatens the garden, bringing in potted plants and tender plants is an ideal way to keep plants for the next spring. There are a couple of problems with bring in plants with the main one introducing insects indoors. I kid you not, I brought in an asparagus fern that hid a spider almost the size of a quarter! Other common insects in potted plants are ants, earwings and pill bugs. Outdoor potted plants can also introduce plant diseases that may spread throughout other houseplants. There are a few ways to avoid these problems.
- tap the pot several times before and after moving which will knock off some insects especially earwings and pill bugs
- brush the pot well to make sure there are no spider nests
- check the plant itself for any spiders, caterpillars or other insects
- spray plants with Safer's soap or a homemade soap solution
- isolate plants from other house plants to ensure insects and/or disease do not spread
