With the arrival of summer, the high temperature and humid climate pose a challenge to the survival of many plants. Cycads, a widely planted ornamental plant in our country, often show yellowing leaves in summer. What are the reasons for the yellowing of cycad leaves in summer? How should we carry out maintenance? This article will answer these questions for you one by one.
Reasons for the Yellowing of Cycad Leaves in Summer1. High Temperature and Drought: Although summer is hot and humid, it is also accompanied by drought, which can lead to cycads being unable to absorb enough water, causing the leaves to turn yellow.
2. Insufficient Light: With strong sunlight in summer, if cycads are kept in a dark environment for a long time, it can easily lead to leaf yellowing.
3. Improper Fertilization: Over-fertilization or unbalanced fertilization can also cause cycad leaves to turn yellow.
4. Diseases and Pests: Summer is the peak season for diseases and pests. If they are not controlled in time, it can also lead to yellowing of cycad leaves.
Care Guide for Yellowing of Cycad Leaves in Summer1. Proper Watering: In the hot and dry summer, keep the soil moist but avoid waterlogging. Water in the early morning or evening, and make sure to water thoroughly each time.
2. Adjusting Light: With strong sunlight in summer, provide appropriate shading to avoid direct sunlight. You can place cycads in a semi-shady environment or use shade nets for shading.
3. Reasonable Fertilization: Follow the principle of "fertilizing less but frequently" in summer, avoid over-fertilization, and choose a compound fertilizer with a suitable nitrogen, phosphorus, and potassium ratio, applying it every 15 days.
4. Control of Diseases and Pests: Regularly inspect cycads, and if diseases or pests are found, control them in a timely manner. You can use insecticides and fungicides, but be mindful of the safe use of chemicals.
5. Pruning Withered and Yellow Leaves: When cycad leaves turn withered and yellow, prune them in time to avoid affecting the growth of the plant.
The yellowing of cycad leaves is a common phenomenon in the hot and humid summer environment. However, by understanding the reasons and taking corresponding maintenance measures, we can effectively prevent this phenomenon. It is hoped that this article can provide some help to cycad enthusiasts. According to the "China Flower News," the planting area of cycads in our country has reached several hundred thousand mu, and summer maintenance of cycads has become an important task.
In future maintenance, we should pay close attention to the growth status of cycads and adjust maintenance measures in a timely manner to ensure that cycads can grow vigorously in summer, adding a touch of green to our lives.
