How to Care for Green Chrysanthemums in Summer
The scorching summer is both an opportunity and a challenge for the growth of green chrysanthemums. Mastering scientific care methods can help green chrysanthemums maintain vigorous vitality during the high-temperature season. This article systematically analyzes the three core techniques for summer care of green chrysanthemums, focusing on key aspects such as temperature control, light management, and water supply, and provides practical illustrations to guide gardening enthusiasts in creating a suitable growth environment.
Summer Environmental Control for Green Chrysanthemums
Precise Temperature Control Strategy
Stabilize the care temperature within the range of 18-22°C, and immediately initiate the cooling program when the temperature exceeds 28°C. It is recommended to use the morning and evening misting method to cool down, and combining it with shade nets can reduce the ambient temperature by 3-5°C. In air-conditioned environments, ensure that the plants are kept more than 2 meters away from the air outlets to avoid alternating hot and cold stimulation.
Creating Day-Night Temperature Difference
Maintaining a temperature difference of about 8°C between day and night can promote nutrient accumulation. At night, you can open the north-facing windows to form natural convection. Use temperature monitors to assist in observation, ensuring that the high temperatures at noon do not exceed the plant's tolerance threshold.
Green Chrysanthemum Light Management Plan
Controlling Shade Periods
Use a sun protection net with 50% light blocking from 10 am to 4 pm, and receive 2-3 hours of gentle sunlight during the early morning and evening. For southeast-facing balconies, you can set up a retractable shade curtain, which can be adjusted flexibly according to the UV index.
Monitoring Light Intensity
Equip a lux meter to measure light intensity, and keep direct sunlight within the range of 15,000-20,000 lux. Immediately increase the number of shade layers when the leaves start to curl to maintain photosynthetic efficiency.
Green Chrysanthemum Water Supply System
Intelligent Irrigation Plan
Follow the principle of watering when dry and keeping it moist, with terracotta pots watered twice a day (morning and evening) and plastic pots watered once a day thoroughly. Use an insertable soil moisture meter to assist in judgment, maintaining the substrate moisture content within the range of 60-70%.
Cooling Mist System
Configure a micro-sprinkler system and perform foliar misting at 10-11 am and 2-3 pm daily, combined with circulating fans to accelerate moisture evaporation and cooling. Avoid misting open flower clusters to prevent waterlogging and rot.
Summer Care Summary for Green Chrysanthemums
Through a three-dimensional care system of temperature gradient management, light cycle regulation, and precise water supply, combined with regular checks of leaf conditions, green chrysanthemums can continue to sprout new buds in summer. It is recommended to apply a 1:1500 amino acid water-soluble fertilizer every two weeks to enhance the plant's resistance and lay the foundation for a burst of flowers in autumn.
