What to Do When the Leaves of a Peace Tree Become Dry
As a popular indoor ornamental plant, the Peace Tree often causes concern among plant enthusiasts when its leaves become dry. This article systematically explains the key points of leaf care for the Peace Tree through cause analysis and practical guides, helping you quickly restore the vitality of the plant.
Analysis of the Four Main Causes of Dry Leaves on the Peace Tree
Care During Environmental Adaptation Period
When the Peace Tree is repotted or experiences a sudden change in environment, it will activate its self-protection mechanism. At this time, the drying of the edges of the old leaves is a normal metabolic process. Maintain an environmental temperature of 18-25°C and avoid direct sunlight. It is recommended to use a hygrometer to monitor the air humidity, keeping it above 60%, and to promote the germination of new leaves by misting to increase humidity.
Adjustment of Soil pH
The Peace Tree is sensitive to soil pH. When the pH of the potting soil is detected to be greater than 7.5, iron sulfate can be used at a ratio of 1:1000 for monthly root irrigation. For daily care, it is recommended to use a mixture of pine needle soil, decomposed leaf soil, and river sand in a ratio of 4:3:3, and to add 5% sulfur powder during the annual spring potting to maintain an acidic environment.
Winter Cold Protection Management
When the temperature drops below 10°C, the Peace Tree will activate its dormant mechanism. At this time, reduce the watering frequency to once a month and use the pot-in-pot method for insulation: place the plant in an outer pot that is 10cm larger in diameter, filling the gap between the two pots with foam granules. In case of a cold wave warning, wrap the canopy with a non-woven fabric insulation cover.
Maintenance of Root Health
In the early stage of root rot, the tips of the leaves may become scorched and the new leaves may wilt. During treatment, it is necessary to completely remove the brown rotting roots, leaving only the healthy white roots. After pruning, soak the roots in a carbendazim solution for 30 minutes, then dry them before using a sterile soil mixture (vermiculite: perlite = 1:1) to promote new root growth. Wait for new buds to sprout before changing to a nutritious soil.
Key Points of Daily Care for the Peace Tree
Keep the potting soil moist but not waterlogged in spring and autumn, mist in the morning and evening in summer to increase humidity, and control water in winter to prevent freezing. Apply a special fertilizer for ornamental plants once a month, ensuring the nitrogen, phosphorus, and potassium ratio is controlled at 3:1:2. Rotate the pot regularly to ensure even light exposure and prune dense branches every spring to improve ventilation.
Through scientific diagnosis and precise care, the problem of dry leaves on the Peace Tree can be effectively improved. It is recommended to establish a care log to record data such as temperature, humidity, and fertilization schedule, and to complement this with regular soil testing to create a suitable microenvironment system for the Peace Tree to grow.
