You can calculate the flowering time from December to new year's day, or even spring festival in Guangdong, and October to November in Guilin. The flowering time and temperature in these areas are suitable. The average daily temperature is 12 ℃, at this time, the flowering period can be as long as 60 days, but if the National Day flowering, the temperature is high, the flowering period is short.
In conclusion, it is suggested that the flowering period should be from the end of October to November, which can not only prolong the flowering period, but also ensure the winter. The northern region can consider October, but the more northward, the earlier.
Water control generally takes three weeks, and it also takes about 20 days from budding to flowering. According to the calculated flowering time, water control starts 40 days in advance. If you want to bloom in October, you need to control water at the end of August.
The water control method is very simple. According to the size of the flowerpot, do not water in the stage of water control. When the flowerpot is short of water and withers, only half of the usual water or sprinkle some water. Every day to ensure that the plant half day withers, half day does not wither. According to the climate, if the weather is sultry, water more appropriately, or do not water in case of rain. In a word, the purpose of water control is to appear the state of leaf withering every day, not sprouting and growing new leaves, so that the plant nutrients are all supplied to the old leaves, and promote the branch maturity and flower bud differentiation.
Pay attention not to apply fertilizer during the period of water control. In the dry state, the absorption of fertilizer is not good and the root will be damaged. However, during the period of water control, the plants are in wilting state, and those with poor mental tolerance should not use water control method, which is very tangled.
After three weeks of water control, sufficient water shall be poured, and then the soil shall be loosened and the roots shall be cut, and the fertilizer shall be applied three times, usually once a week, twice before flowering, and once again when the flowers are full, so as to promote the bud germination.
In order to control the length of inflorescence, make the flowers concentrated and plant compact when flowering, Paclobutrazol was used once to restore watering, with a concentration of 2 /10000.
