Here we have the 10 inch hanging basket dark leafed Begonia. The dark leaves take full sun. However, a Begonia also comes in a light color which takes only the shade. You can use it in a hanging basket. Then we have what you call the Double Begoias which takes full sun or they can be put in shade. These Begonias take little water. You can water every three to five days which would be perfectly fine. Every seven to ten days you can fertilize again with the Miracle Grow. Again we use the Slow Release Fertilizer when we make our baskets. Always remember to lift your basket up to check for your water. If it is dry you make for sure you put water in it until you see the water come over the sides.
