I "feed" my hibiscus monthly with fertilizer sticks. Should I continue this practice when I bring it in for wintering?
No fertilizer in winter: plants don't grow much due to the low light level. Unless you have a true tropical hibiscus, your plant needs to have a dormancy period to reset its flowering schedule. Monitor moisture level carefully - it will likely need less than when outdoors and growing vigorously.
