In summer, bougainvillea needs plenty of sunshine and water during its growth. The watering time depends on the degree of dryness and wetness of the soil and the evaporation rate of water. If there is no water at a depth of 3 cm, it means that it is time to water. May-July is the best fertilization time, and the appropriate fertilization times are 2-3 times a month. It is recommended not to fertilize after August.

Summer maintenance is the key to a large number of bougainvillea and a long flowering period. First of all, from the perspective of light, bougainvillea likes light and is suitable for growing in places with sufficient light. For example, a balcony with good light is more suitable for planting potted bougainvillea.

Secondly, because of the high temperature in summer, bougainvillea, which often grows in the sun, evaporates quickly and needs to keep enough water. If you don't water it in time, the leaves will wither easily the next day, or even turn yellow and fall off. The watering time can be seen from the soil in the flowerpot. The color of the soil in the flowerpot is white, and there is no water in the depth of 3 cm, indicating that it is time to water. The watering amount only needs to thoroughly irrigate the soil.

fertilize the soil or land

Finally, the problem of fertilization. If bougainvillea grows well, the fertilization time should be from May to July every year. Fertilization is mainly a compound fertilizer of phosphorus and potassium, because it grows fast during this period and needs a lot of nutrients. The number of fertilization should be controlled at 2-3 times a month, and the amount of fertilization should not be too much. Fertilization is not recommended because the amount of nutrients it needs will decrease after August.
