The genus Bougainville includes about 40 species of shrubs and vines. The decorative attractiveness of the plant is given by bracts of inflorescences, painted, depending on the variety, in white, pink or red. Basically, bougainvillea is used to decorate walls, balconies, etc.
When growing bougainvillea, it should be borne in mind that the plant needs a mild climate, only in this case it can be cultivated in open ground. At home, bougainvillea is grown in a sunny, warm room. In order to achieve repeated flowering indoors, the plant must be placed on the balcony after the flowering period has ended.

Bougainvillea is a photophilous plant, therefore it is necessary to grow it in a place brightly lit by the sun.
Bougainvillea does not tolerate temperature drops below 7 degrees. In summer, the optimum temperature should be 20-22 degrees, the maximum limit is 32 degrees.
In summer, bougainvillea requires frequent, plentiful watering. In winter, watering is reduced. The plant responds well to the high content of calcium and magnesium salts, so you can water it with hard water.
Potted plants are required to be transplanted annually into a larger container, however, it should be borne in mind that, compared with the aboveground part, the pot should not be too large.
The soil for the plant should be soft and fertile. It is necessary to provide good drainage, which will not allow stagnation of excess moisture.
Bougainvillea flowers appear on last year's shoots. It is necessary to carry out constant pruning of dry branches and side shoots, reducing them by 2/3 of the length. Potted specimens are cut more intensely.
Propagated by bougainvillea apical cuttings. In summer, shoots about 7 cm long are taken from young branches and placed for rooting in a well-drained soil at a temperature of 22-24 degrees. Lignified cuttings are taken in January, their length should be approximately 15cm. The rooting temperature in this case is about 18 degrees.
