These tropical climbers are suitable for large containers placed in the garden during summer but must be kept frost-free in winter.
Sunlight: For the best results put your plants in full sun. If you want good blooming give them at least 5 hours a day of full sunlight as a minimum. More hours of direct sun is better. Less than 5 hours and the plant may not bloom very well. Your plants will thrive in shade or partial shade, but only have nice growth with little or no blooms.
Soil: They thrive in almost any soil as long as it is well drained and fertile. Soils that work for other plants you grow will be fine.
Water: Make sure you dont let the plants dry out between waterings. If you want to be successful. keep containers moist but also they need to be well drained. No sitting plants in standing water.If growing in pots, DO NOT USE SAUCERS under your pots. A healthy container grown plant will drink a lot of water during the warm times of the year. In cooler periods or when you bring your plants indoors for the winter, the water requirement will be much less.
Temperature: Bougainvilleas are hardy throughout the South but young growth will be damaged by frost. Optimum growing temperatures are warm days.
A light frost will not kill the plant, but you can soon expect all the leaves and bracts to fall off. In this case, the plant will regrow if not subjected to more frosts for longer duration.
Fertilizer: Mature plants can be heavy feeders. Here is some quick fertilizer tips.
High phosphorus with micronutrients, as well as additional iron and magnesium
Slow or timed release fertilizers are acceptable. Make sure you follow the fertilizer label
Plants grow best with small amounts of nutrients constantly available
Do not apply fertilizers to dry soil, Do not overfertilize, in this case less is better than more
