What Causes the Curled Leaves of a Fortune Tree
As a star variety of indoor green plants, the curling of fortune tree leaves is a common maintenance problem. This article provides real-shot symptom illustrations and scientific solutions to help you quickly identify the cause of the disease and implement effective treatment.
I. Abnormal Leaves Caused by Environmental Factors
1.1 Analysis of Symptoms Caused by Intense Sunlight Burn
From late spring to early autumn, between 10:00-15:00, when the UV intensity exceeds 2000μW/cm², the cuticle layer of the leaves will show dehydration wrinkles. This can be improved by installing a 30% light-blocking shade or moving it to an east-facing windowsill.
1.2 Humidity Control Techniques
It is recommended to maintain the air humidity between 60-75%. Using a humidifier with a misting function provides the best results. During the winter heating period, a humidity meter can be used to monitor, and local humidity can be increased by placing wet pebbles in a tray.
II. Solutions to Biological Invasions
2.1 Identification and Treatment of Pests
Focus on checking for red spider mites (0.5mm red spots on the back of leaves) and scale insects (white waxy protrusions). Use abamectin (diluted 1500 times) to spray weekly, combined with 75% alcohol cotton swabs for physical removal.
2.2 Disease Prevention Measures
Use carbendazim 800 times solution to water the roots monthly, preventing fungal diseases such as (T-J) disease. Pruning tools need to be disinfected at high temperatures, and wounds should be coated with wood ash to accelerate healing.
III. Systematic Maintenance Suggestions
Establish a "3-checks-1-record" system: check the front and back of the leaves, the moisture of the potting soil, and the spacing of the plants weekly; record the watering and fertilizing times. Apply slow-release fertilizer (N-P-K=15-5-10) in spring and autumn, stop fertilizing in summer, and supplement with potassium dihydrogen phosphate in winter.
By precisely controlling the light intensity, scientifically supplementing water and increasing humidity, and regularly preventing and treating pests and diseases, combined with a systematic maintenance plan, the fortune tree can maintain a tall and graceful appearance, becoming a permanent green landscape in your home.
