Place gloxinias in a bright area, a location near a window, away from direct sunlight is ideal. The growth of gloxinia plants flourish in average room temperatures between 16-24 C. Watering, often enough to keep the soil moist pot not to porridge. Leaves develop brown spots if they get wet, so apply water directly to the soil, not to the leaves. If allowed to dry completely, the gloxinia goes dormant. Use a liquid feed every two weeks on your flowering gloxinia plant.
