Management of Twelve 卷 under High Temperature in Summer
Today, the editor will elaborate on the experience of raising the Twelve 卷, focusing on the management of Twelve 卷 under high temperatures in summer. Next, a comprehensive introduction will follow.
Many flower enthusiasts always consider Twelve 卷 to be dormant or semi-dormant in summer, but this is not the case. In the past few years of my cultivation, I have made some mistakes and lost some things, but I have also learned a lot. Now, let me introduce my cultivation experience.
Let's talk about the management during the high-temperature season:
1. Twelve 卷 is more heat-tolerant than we think, but there is a limit and it should not exceed 42 degrees (ambient temperature).
2. Temperature difference is crucial for Twelve 卷, with a difference of more than 10 degrees being very necessary for them. Otherwise, they will grow extremely slowly in a high-temperature environment with little temperature difference and are prone to root rot and necrosis.
3. Twelve 卷 is very sensitive to light. 40% shading causes the plants in the north to turn brownish-red, with slow or halted growth. 65% shading results in normal growth and green leaves, while more than 80% shading causes the leaves to turn emerald green with a stretching phenomenon.
4. Ventilation for Twelve 卷 is essential in summer. Even with proper shading, the pot can still be heated by the sun. Adequate ventilation and appropriate watering can remove the heat and reduce the ambient temperature. It can also remove excessive humidity during rainy days and prevent the occurrence of diseases and pests in summer.
5. Watering is crucial for Twelve 卷, especially in summer when the evaporation rate is high. Once the pot dries out completely, it can cause significant damage to the roots. My method is to fill an empty pot with the same substrate, water it thoroughly, and place it in the same environment to observe how many days it takes to dry out. This way, you can estimate the watering interval. Flower enthusiasts might want to try this method.
6. Do not repot or propagate by cutting Twelve 卷 in summer when the temperature is high and it is not easy for them to root.
Let's also discuss some bad phenomena that occur when growing Twelve 卷 in summer:
1. Leaf tip drying: This phenomenon occurs more frequently in summer. From my observations, it is mainly caused by reduced water absorption due to root damage and high evaporation rates. The treatment method is to first check for root rot and change the pot if necessary. If not, move it to a cool and ventilated place to recover.
2. Brown spots on leaves, which sink and cause leaf drying without spreading; this phenomenon occurs when some flower enthusiasts like to use transparent containers to cover the plants, leading to this issue. It might be caused by water droplets on the container walls forming a lens effect under sunlight, burning the leaf surface. The solution is not to use containers to cover the plants.
The above is the full content on the management of Twelve 卷 under high temperatures in summer. I hope it can help you and also hope that everyone will come to see more green plant and flower experience and knowledge!
