Red hydrangea, also known as red xiandan, long boat flower, belongs to the Rubiaceae family and is native to the southern regions of China. It is also distributed in places like Myanmar and has certain medicinal values, including dispersing blood stasis, stopping bleeding, regulating menstruation, and lowering blood pressure. The main propagation method of red hydrangea is cutting. Next, let me introduce its cultivation methods.
I. Cutting Methods
1. Choosing cuttings
It is best to choose semi-hardened branches with a diameter of more than 3 millimeters and a length of 10-14 centimeters in spring and summer. After cutting, the cuttings can be dipped in solutions like indole butyric acid for a few seconds.
2. Soil selection
Generally, use well-ventilated and moisture-retaining soil as the cutting medium, and mix pearl rock, vermiculite, and river sand in a certain proportion.
3. Cutting time
Usually choose to cut in late spring to early summer when the temperature is around 15-25 degrees Celsius. After cutting, it is important to shade it in time until it develops roots.
II. Maintenance Methods
1. Light
Red hydrangea loves light. Besides shading it after cutting and placing it in a cool place, it should be provided with sufficient nutrients at other times.
2. Temperature
Red hydrangea enjoys heat and is not cold-resistant. The optimal temperature range for its growth is between 23-32 degrees Celsius. When the temperature in winter drops below 10 degrees, the growth rate of the plant will significantly slow down, eventually entering a dormant period.
3. Soil
Plant red hydrangea in fertile soil with good drainage and aeration, preferably in acidic soil. If the soil is alkaline, you can use some acidic liquid fertilizers to lower the pH value of the soil.
4. Fertilizer
Generally, nitrogen and phosphorus fertilizers are used. More nitrogen fertilizer can be applied during the germination period, and the content of phosphorus fertilizer can be increased during the bud formation and early flowering stages.
