About 18 different species of plants belong to the genus Bougainvillea, all of which originate from South America and all of which are able to offer us a unique and wonderful spectacle through their flowering. These climbing shrubs can grow up to 13 yard high and, depending on the climate, bloom all year round. In a climate like ours, they bloom from spring until late fall. Contrary to what it may seem, bougainvillea flowers are small and white, surrounded by bracts that take on different colors and have a papery texture. Bougainvillea needs full sun to bloom properly. For this reason, this species should not be treated as an indoor bonsai. Bougainvillea bonsai must be protected from frost and wind. In any case, do not be alarmed if the plant loses its leaves during the cold months: This is part of its life cycle.
Potting soil for bougainvillea bonsai
Bougainvilleas have a very thin and delicate root system, so it is important to use a porous and acidic potting soil.
Watering Bougainvillea Bonsai
Water when the topsoil begins to dry. It is important to keep the potting soil moist but avoid waterlogging. Remember to use reverse osmosis water, as the presence of dissolved salts in the water can change the pH of the soil.
Pinch and prune the bougainvillea bonsai
Bougainvilleas are climbing shrubs, so they tend to form shoots at the tips, which in turn serve to cling to other trees. To shape the structure of the bonsai, pinch the acids more intensely to help distribute the “vigor” to the lower branches. Perform pinching after flowering. Pruning at two buds is recommended to strengthen the plant and stimulate the growth of new branches directly from the old trunk.
Bonsai Wiring
It is not recommended to excessively wire a bougainvillea bonsai, as its branches can easily break or dry out from the wire. In any case, do this on shoots that are still tender to give direction to their growth.
