Answer: You can repot gloxinia tubers each spring, generally in fresh soil in the same container. If the roots continually grow out of the bottom of the pot, use a larger pot the next time you repot the tuber. At the end of the season, after the leaves turn yellow, allow the soil in the pot to dry out. Then store the plant, pot and all, over the winter. Don't water during this resting phase. In the spring remove the tuber from the pot, brush off the potting soil, then repot in fresh potting soil. Keep soil barely moist until new shoots appear, then water regularly, provide bright light (but not direct sunlight), and use tepid water to keep the soil moist but not soggy wet.
Hope this clarifies things for you!
