How to acclimate chrysanthemums after potting
As a traditional famous flower in China, the survival rate of chrysanthemums after repotting directly affects the quality of blooming later on. Mastering scientific acclimation methods can help the plant quickly adapt to the new environment. This article systematically explains the key points of caring for chrysanthemums after repotting from three critical dimensions.
Core care methods for chrysanthemum acclimation
Best time for transplanting
In spring and autumn (March-April / September-October), when the daily average temperature is stable at 18-25°C and the air humidity is maintained at 60%-70%, repotting at this time can reduce root damage. In the southern region, it can be extended to mid-November, and in the north, it is necessary to avoid the frost period.
Specialized substrate mixing plan
It is recommended to use a golden ratio of peat soil: perlite: decomposed leaf soil = 5:3:2, and add 5% bone meal to enhance nutrients. Choose a terracotta pot, with a diameter 5-8 centimeters larger than the original soil ball, and place a 3cm layer of ceramsite at the bottom for drainage.
Four elements of environmental regulation
① Light: Place in a diffused light environment after potting, and gradually increase the duration of direct sunlight after 7 days. ② Humidity: Mist the leaves in the morning and evening, keeping the substrate slightly moist without积水. ③ Ventilation: Ensure 4 hours of air circulation every day. ④ Temperature: Keep the temperature at night no lower than 15°C and avoid exceeding 32°C at noon.
Signs of successful chrysanthemum acclimation
Signs of new tissue development
Observe the expansion of the top bud 15 days after repotting, and new tender green leaves can be seen about 20 days later. It is normal for the bottom 1-2 old leaves to turn yellow and wither, and they should be trimmed in time to avoid nutrient consumption.
Root stability testing method
Use the three-point positioning method to test: gently lift the base of the plant to feel the soil grip; observe the bottom of the pot for new white roots that are faintly visible; tap the pot wall, and a dull sound indicates dense roots.
With systematic care, chrysanthemums usually complete acclimation within 25-35 days. During this period, it is necessary to maintain a stable care environment and avoid frequent moving of the pot. When the plant shows a continuous growth trend, a phosphorus-potassium fertilizer diluted 1000 times can be applied to promote bud differentiation.
