How to Care for White手掌 in Winter
As a representative of tropical ornamental foliage plants, white palms require special attention during the winter. This article systematically analyzes five core maintenance techniques to help your white palm safely survive the winter, maintain glossy leaves, and continue blooming.
I. Double Assurance of Environmental Regulation
1.1 Accurate Temperature Control
Maintain a temperature range of 10-15℃. At night, a mini greenhouse can be set up using double-layer plastic bags and a frame. Open holes for ventilation after 10 am during the day. Avoid direct exposure to heating vents in the north, and it is recommended to use a temperature-controlled heating mat in the south without heating.
1.2 Scientific Light Distribution
In winter, ensure 4-6 hours of scattered light per day. Combine south-facing window sills with gauze curtains to filter strong light. Rotate the pot 180° every 10 days and use smart grow lights to extend the lighting to 8 hours to promote bud differentiation.
II. Golden Rules for Water and Fertilizer Management
2.1 Control of Watering Cycle
Use the "three-finger detection method": Insert your fingers into the soil up to the second joint, and water thoroughly if dry. Keep the soil slightly moist in an environment above 18℃, and strictly control water in low-temperature environments. Water during noon, and the water temperature should be the same as the room temperature.
2.2 Strategy for Nutrient Supply
Stop fertilizing below 15℃, and in heated rooms, apply a diluted foliage plant-specific liquid fertilizer (1:2000) once a month. Spraying potassium dihydrogen phosphate (1:1500) on the leaves can prevent leaf edge scorching.
III. Key Measures for Disease Prevention
3.1 Humidity Balance Plan
Use a humidifier to maintain 50%-60% air humidity, combined with the evaporation method using pebble trays. Avoid spraying in the evening and use a misting spray bottle to spray at a 30cm angle away from the leaves.
3.2 Key Points for Ventilation and Disease Prevention
Ensure 2 hours of air circulation daily, using a circulating fan on low speed. Regularly wipe the back of the leaves with garlic extract solution, and immediately kill aphids with 75% alcohol cotton swabs.
By precisely adjusting temperature, light, and water fertilizer, combined with a scientific disease prevention system, white palms can not only safely survive the winter but also accumulate energy for blooming. It is recommended to repot and prune roots in early March, using a new substrate of peat soil and perlite (4:1) to prepare for the spring growing season.
