How to Care for (X-D) Grass in Winter
As the temperature gradually drops, whether (X-D) grass can safely survive the winter becomes the most concerning issue for caregivers. This type of fragrant herb with air purification functions requires special attention to environmental regulation during winter care. Mastering scientific care methods can not only help the plant survive the winter smoothly but also maintain its unique ornamental value.
Key Points for Winter Care of (X-D) Grass
Light Control and Placement
In winter, the plant should be moved to a south-facing windowsill to ensure 4-6 hours of direct sunlight daily. In northern regions, supplementary lights can be used, maintaining a distance of 30-50 centimeters from the plant to avoid leaf burns. Rotate the pot by 90 degrees weekly to ensure even light exposure.
Temperature Management and Cold Protection Measures
Maintaining a temperature of 10-15°C is ideal, with night temperatures not falling below 5°C. In rooms with underfloor heating, raise the pot by 3-5 centimeters and use a humidifier to maintain 40% humidity. For outdoor plants, it is recommended to use double-layer insulation film, with an air gap of 2 centimeters between layers for better effect.
Adjusting Pruning Rhythm
Stop shaping pruning from November to the following February, only removing withered and old leaves. Retain stems 15 centimeters or taller and apply wood ash to the cuts to prevent fungal infection. Keep enough leaves for photosynthesis to help accumulate nutrients for overwintering.
Water Control Techniques
Use the "lifting pot method" to determine when to water, adding water when the pot soil is 1/3 lighter. Use warm water at 25°C during the noon to water slowly around the pot edge. Add phosphorus acid potassium (0.1% concentration) once a month to enhance cold resistance.
Protection Strategy for (X-D) Grass Frost Damage
When the temperature continuously drops below -3°C, the plant may experience cell freezing damage. Initially, the leaves will appear translucent, and they should be moved to a 10°C environment to defrost slowly. Severe frost damage is indicated by blackened stems, which need to be immediately cut off and treated with carbendazim.
Through scientific environmental control and meticulous care, (X-D) grass can not only survive the winter safely but also rejuvenate in the spring. Regularly observe the plant's condition and adjust the care plan flexibly according to regional climatic characteristics to allow this functional green plant to continue playing its role in purifying the air.
