As soon as possible after receiving the Begonia rex, plant it in a flower pot. Choose a pot with holes in the base with a saucer for drainage. Or use an ornamental pot with an inner pot so that the water can be collected. Sprinkle a layer of hydro granules over the bottom of the pot, cover with fresh potting compost and plant the root ball of the Begonia rex at the correct depth. Fill with compost, allowing sufficient space at the top for watering and press firmly. Water generously after planting and place the pot in a cool place in partial shade. Avoid a sunny windowsill as direct sunlight could cause leaf-burn.

Always keep the soil moderately moist, do not allow it to completely dry out. During the growing period add some plant food when watering on a regular basis. This leaf begonia loves a high humidity. Preferably choose a cooler spot and not above the central heating radiator.
