Begonias are versatile flowering tubers. They will grow indoors and out. In areas that are hot and humid they fair better as house plants. They have long-lasting blooms and large leaves. Growing them in containers keeps the plant compact though blooms may still reach 8 inches in diameter. These are easy plants to care for once they are established.
Fill starter pot ¾ of the way with loose potting soil. Place tuber in hollow side pointing up, and cover lightly with potting soil, about one inch. Water thoroughly once until sprouting begins. Do not allow the soil to become dry.
Transplant into a permanent pot once sprouts are 1 to 2 inches tall. Fill flower pot ¾ of the way with potting soil that has been mixed with vermiculite. Use your finger to make a hole big enough for the root system, and gently place the plant in. Cover with 2 inches of soil, and water lightly.
Move containers outdoors once all danger of frost has passed. Remove any leaves that turn yellow as soon as possible, as well as any stems that are longer than others to keep a uniform appearance. Fertilize once per month.
Bring containers indoors when frost becomes imminent. Place in a sunny location to begin with, and slowly lessen the amount of sunlight that the plant receives. This will allow it to adjust to being indoors.
