How to Care for a Happiness Tree in Winter
Winter is a crucial period that tests one's ability to care for a happiness tree. As a typical tropical ornamental leaf plant, the happiness tree is extremely sensitive to low temperatures and will show symptoms of frostbite such as yellowing leaves and leaf fall when the temperature drops below 10°C. Mastering scientific overwintering management methods can not only help the plant survive the cold winter safely but also store energy for the following spring's growth. This article will systematically analyze the five core elements of caring for a happiness tree in winter, from environmental regulation to water and fertilizer management.
Key Points for Winter Environmental Regulation
Temperature and Wind Protection Management
When the temperature drops to 15°C, it's time to start taking measures against the cold: prioritize moving the plant to a south-facing enclosed balcony or a bright indoor area, and make sure to keep it more than 1.5 meters away from heating equipment. Especially at night, a double-layer protection method can be used - first wrap the plant with a transparent heat-insulating film and then cover it with a cotton cloth bag. Remove it promptly after sunrise the next day.
Optimal Lighting Solution
In winter, ensure at least 4 hours of direct sunlight daily, and rotate the pot 180° weekly using a rotating cultivation method to ensure even exposure to light. In case of consecutive cloudy and rainy weather, it is recommended to supplement with LED plant grow lights 50cm away from the tree canopy for 2-3 hours daily, taking care to avoid direct contact between the lights and the leaves.
Tips for Water and Fertilizer Management
Scientific Water Control Plan
Adjust the watering frequency to 1/3 of that in summer, using the 'lifting pot method' to judge: when the pot feels significantly lighter when lifted, choose a sunny morning at 10 o'clock to water slowly with 25°C warm water along the pot edge. It is recommended to use the bamboo stake test method, inserting the stake 2/3 into the potting soil, and only water when no moisture is felt after pulling it out.
Overwintering Fertilization Stop Principle
Completely stop fertilizing from November to the following February, but apply potassium dihydrogen phosphate (diluted 1500 times) as a cold resistance preparation 20 days before winter. Special attention should be paid to avoiding the residue of nitrogen-containing fertilizers, and promote the decomposition of fertilizer effectiveness through loose soil maintenance to prevent winter fertilizer damage.
Handling Special Conditions
When slight frostbite (yellowing at the leaf edges) occurs, immediately move it to a 15°C environment, prune the damaged leaves, and apply wood ash to the cut. For severe frostbite (shrinking branches), emergency repotting is needed, removing the decayed roots and soaking in carbendazim before replanting with new soil.
Through precise regulation of temperature, lighting, and water and fertilizer, combined with necessary physical protective measures, the happiness tree can safely overwinter indoors in the north. It is recommended to regularly monitor the environmental humidity with a hygrometer and maintain it within the appropriate range of 50%-60%, allowing this symbol of happiness green plant to accompany you through every cold winter.
