Complete Guide to Bougainvillea Cultivation Methods and Precautions

Bougainvillea is an evergreen climbing shrub with a long blooming period, bright and beautiful flower colors, and small, delicate flowers. Every three bracts cluster together to form a triangular flower, which is why it is also called paper flower. So how should bougainvillea be grown? What should be noted when cultivating it? Let's find out together.

1. Soil Selection

Bougainvillea does not have high requirements for soil, but a fertile and breathable soil is preferable. Generally, it can also be used after cow manure, leaf mold, and sand are piled up and decomposed. For cultivation today, mixing garden soil with leaf mold and sand together is sufficient.

2. Watering and Fertilizing

Bougainvillea likes a humid environment, so its water demand is relatively high, especially in the hot summer. At this time, lack of water will directly cause yellowing leaves and drying out in bougainvillea, and it will also affect bougainvillea flowering. Therefore, during the summer blooming period, bougainvillea should be watered twice a day, sprayed in the morning and watered in the evening, and watering should be appropriately reduced after the flowers fade. Bougainvillea blooms heavily and consumes relatively more nutrients, so bougainvillea likes fertilizer. After the temperature warms up in spring, generally apply nitrogen fertilizer about once every half month, apply cake fertilizer once a week during the growing period, apply phosphate fertilizer as a top dressing in late autumn, reduce fertilizing in autumn and winter, and stop fertilizing in winter.

3. Light and Temperature Requirements

The suitable growing temperature for bougainvillea is between 20-30 degrees. In winter, below 5 degrees, it is prone to cold damage that causes leaf drop, so the temperature must be well controlled. In summer, pay attention to cooling, and in winter, pay attention to keeping warm. Bougainvillea is a flowering plant that likes light. During the growing season, if there is insufficient light, the plant's growth will not be vigorous enough, affecting flowering. Insufficient light will also cause it not to bloom.

4. Precautions

Bougainvillea should be fertilized with decomposed fertilizer. Fertilization should be done in small amounts and multiple times, and the concentration should be light, so as not to damage the root system and affect its growth. Bougainvillea should have watering controlled before flowering. Normally, watering should follow the principle of not watering when not dry and watering thoroughly when watering, so that the flowers bloom neatly. Bougainvillea grows quickly, has a developed root system, and has many fibrous roots, so it should be repotted once a year. In addition, because of long-term watering and fertilizing, the potting soil is very prone to compaction, so the soil should be loosened regularly and weeds removed to facilitate its growth; otherwise, it will cause root rot and poor growth.
