Bougainvillea peruviana

The great bougainvillea prefers abundant light, which promotes vigorous growth and a lush appearance. While young, it can tolerate somewhat lower light levels. Insufficient light may lead to poor flowering, whereas too much can scorch the leaves. Native to sunny environments, it is adapted to strong sunlight.

Great bougainvillea grows best in its native habitat with warm temperatures between 20 and 38 °C (68 and 100 °F). It favors hot, dry conditions and can withstand temperatures up to 48 °C (118 °F) without much trouble. In colder periods, it may need temperature adjustments through indoor care or protective coverings.

The best time to fertilize a Great bougainvillea is in early spring as it comes out of dormancy. This encourages overall growth and the development of flowers. Fertilization improves the foliage, stems, and branches, and promotes flowers that are large, vivid, and long-lasting. It also helps move nutrients from the roots to the flowers and enhances the plant's health and resistance to disease.

When repotting Great bougainvillea, choose a pot 1-2 inches (2.5–5.1 cm) larger with ample drainage. Use a well-draining potting mix. Repot in spring or fall, ensuring that the root ball is slightly lower than the rim of the flower pot. Water thoroughly after repotting and place in a warm spot with indirect sunlight.
