Bougainvillea – Proper Care for the Wonder Flower

The bougainvillea, also known as the "Drillingsblume" (Three-flower), is a highly popular plant, especially among our European neighbors in the Mediterranean region. It’s no surprise that many associate their best vacation memories with these beautifully blooming shrubs and are eager to bring their rich beauty into their own gardens.

Of the 18 known species, most are climbing plants in their native South America and are commonly grown to adorn building parts, walls, and garden sheds. These fast-growing flowering shrubs are quite successful in this role, often requiring regular, drastic pruning.

In our regions, bougainvilleas are usually offered as shrubs or small trees in pots and containers. Anyone deciding to purchase such a wonder flower or propagate new plants in spring from stem cuttings should reserve a very bright location for their new plant. Direct sunlight is essential for the bougainvillea to produce its stunning flowers. During the frost-free period, this can also be outside on a terrace or balcony.

During the growth phase, make sure that the nutrient-rich substrate doesn't dry out and water regularly. To start the dormant period, it’s best to significantly reduce the amount of water. In winter, simply ensure that the soil doesn’t dry out completely.

A mixture of compost soil and peat is ideal, as the bougainvillea has high nutrient requirements. However, regular potting soil also works. The best time to repot is early spring, and once the plant begins growing, apply a regular liquid fertilizer once a month. When the flowers appear, you can switch to a special flowering fertilizer.

Although the bougainvillea is technically an evergreen plant, it is possible that it will shed its leaves for a short time during winter in our regions.

Since the bougainvillea is a fast-growing plant, it’s advisable to prune it at the beginning of the growth phase in spring. For this, cut back the long shoots, leaving only two buds. If necessary, you can also reduce about one-third of the overall volume. To maintain a bushy shape and ensure abundant blooming, you can trim your bougainville every four weeks.
