What's going on with the dried leaves of the wealth tree?
As a beloved indoor foliage plant, the problem of dried leaves on the wealth tree troubles many plant enthusiasts. This article will systematically master the causes and solutions for leaf drying through specific maintenance scenarios and combining five key maintenance points.
I. Soil compaction causes root hypoxia
1.1 Analysis of the causes of compaction
The roots of the wealth tree are fleshy roots. Long-term use of heavy clay soil can lead to: ① Loss of organic matter ② Imbalance of pH value ③ Porosity drops to below 15%. Experimental data shows that when the soil bulk density > 1.4g/cm³, the root water absorption efficiency is reduced by 60%.
1.2 Improvement plan
It is recommended to repot every 2 years. The substrate ratio is recommended as follows: peat soil 40% + perlite 30% + decomposed leaf soil 20% + vermiculite 10%. After repotting, using HB-101 plant vitality essence can improve root adaptability.
II. Light imbalance causes leaf burn
2.1 Standard of light intensity
Suitable light range is 500-1500 lux: ① Accept direct morning light in spring and autumn ② Need 50% shading in summer ③ Full sunlight in winter. When using a lux meter to test, if it exceeds 2000 lux, shading is required.
2.2 Remedial measures
If sunburn spots appear, immediately move to a scattered light environment, spray with brassinolactone 500 times liquid, and cut off the leaves that are damaged more than 50%.
III. Double impact of humidity imbalance
3.1 Management of air humidity
Keep 60-70% relative humidity: ① Use a thermometer and hygrometer for real-time monitoring ② Use an ultrasonic humidifier ③ Set a cobblestone water tray at the bottom of the pot. Special attention should be paid to the winter heating period when humidity often drops sharply to below 30%.
3.2 Leaf cleaning skills
Wipe the leaves with beer diluted solution (1:20) every week, which can remove dust and supplement amino acids. Avoid wiping the newly sprouted tender buds.
IV. Hidden culprit: improper watering
The details of watering that most people overlook: ① Water in the early morning in summer ② Water in the afternoon in winter ③ Using the immersion pot method can ensure uniform moisture. Use a soil moisture meter, and water when the value is below 30%.
V. Disease and pest defense system
Regularly check the back of the leaves to prevent red spider mites: ① Spray neem oil monthly ② Keep the environment ventilated ③ Isolate immediately when pests are found. Use yellow and blue sticky traps for physical control.
By systematically maintaining the above five dimensions and combining the practical operation diagrams in the text, the problem of dried leaves on the wealth tree can be effectively solved. It is recommended to establish a maintenance log, recording data such as temperature, humidity, and watering cycles, and gradually find the maintenance rhythm that suits your home environment best.
