1. Flowering period

Triangle plum can blossom all year round, but it is difficult to do family breeding. Generally, it blooms only once a year. The higher the latitude, the earlier the flowering time

In Guangdong, Hainan and other places with suitable climate, it has a long flowering period and can bloom from December to February of the next year; In the relatively cold north, such as Beijing and other places, its flowering period is relatively short, and it usually blooms around October

2. Curing method

Planting trigonometry plum needs to provide sufficient sunlight every day, and the illumination time should be kept between 8-10 hours. When planting in the north, pay attention to the control of water in summer, and ensure the indoor temperature in winter, which can not be lower than 8 ℃, so as to ensure the illumination for 8 hours. In addition, pay attention to the application of phosphorus and potassium fertilizer and the pruning of flower branches
