Light : Keep this baby out of bright sun in the sunnier months. You can easily scorch the leaves. A bright, lightly shaded spot will probably do your begonia best. These are shade tolerant.
Water: Allow the top couple of centimetres dry out before you water him.
Humidity: keeping your begonia moist will keep those leaves from crisping.
Temperature: Your normal household temperature will keep him happy.
Food: You can feed your begonia in the warmer months.
Toxicity: This is not one for nibbling critters.
