After your begonia
starts looking like the one above, you can transplant it into a larger container or outside (make sure the weather has warmed up and the danger of frost has passed). If you do move your begonias outside, choose a part shade location that doesn't get too much hot, midday sun. Morning or late afternoon sun is best. Water when the soil is dry to the touch and be sure to check more often during dry, hot weather. Removing spent blooms and wilted leaves will encourage your begonia to bloom longer and prolong its beauty.
