Lagerstroemia Zhu Dinghong

Zhu Dinghong is a bulbous flower, also known as Pogostemon fragrans and safflower. The natural flowering period is generally from April to June, and autumn is the last growing period, which is also the stage of accumulating nutrients and preparing for dormancy after planting bulbs, so autumn will not bloom in non-greenhouse environment. Moreover, with the continuous decrease of environmental temperature, the leaves will turn yellow slowly before and after the first frost and enter a dormant state. At this time, it is necessary to dig out the seed balls or put them in a greenhouse environment for wintering. The winter temperature in the south will not be below zero for a long time, so they can overwinter on land.

Zhu Dinghong is not cold-tolerant, and has the characteristics of short dormancy period in autumn and winter;

Although Zhu Dinghong is a perennial herb, it is not hardy and has a short dormancy period in autumn and winter. September to 65438+ 10 is the golden period of bulb nutrition return and rejuvenation. Therefore, it is necessary to strengthen the light and supplement the diluted phosphorus and potassium fertilizer appropriately, so that the bulbs can be full again before complete dormancy. When the ambient temperature drops to about 5- 10℃, the leaves will slowly turn yellow and completely enter the dormant state. In the northern area, if you choose not to take protocorms for dormancy, it is generally necessary to move the flowerpots indoors for wintering after the first frost, keep the ambient temperature at about 65438 00℃, and still give them proper light and a small amount of living water to make them pass the dormancy period smoothly. The dormant period in Zhu Dinghong is not very long, generally lasting about 2 months, and it will enter the growing period again after the climate warms around the Spring Festival.

Although Zhu Dinghong can't blossom in autumn, it can be planted out of season and may bloom again during the Spring Festival.

Although Zhu Dinghong generally does not bloom in autumn and winter, it can be cultivated in greenhouse after low temperature vernalization to make it bloom during the Spring Festival. There are also some experienced gardeners who use the heated greenhouse environment to raise the ambient temperature appropriately, so that Zhu Dinghong can end its dormancy in winter ahead of schedule, and create suitable ambient temperature and light conditions, and use the combination of phosphorus and potassium fertilizers to promote flowering, and also successfully realize the example of making Zhu Dinghong blossom ahead of schedule during the Spring Festival.
