Do not place this young plant in direct sunlight. Gradually introduce it to more sun as it matures. Tropical bougainvillea prefer full morning sun and light shade during the afternoon. ALWAYS PROTECT FROM TEMPS BELOW 50! Tropical bougainvillea are easily damaged by cool weather! 

Bougainvillea's like moist well drained soil. Don't let it get bone dry but don't keep it soaked either. Just evenly moist & well drained. Reduce water in winter.
