How should one care for the bougainvillea in winter? This article will unveil the secrets to caring for bougainvillea in winter.

Reasons for Leaf Drop in Bougainvillea in Winter

1. Insufficient Light: With shorter daylight hours in winter, bougainvillea may not receive adequate light, leading to slow growth and prone to leaf shedding.

2. Low Temperature: The cold winter temperatures can be harsh on bougainvillea, which is not cold-tolerant. If the temperature drops too low, it can cause frost damage and lead to leaf drop.

3. Improper Watering: Bougainvillea requires less water in winter, and excessive watering can lead to root rot, causing leaf shedding.

4. Improper Fertilizing: Bougainvillea needs less fertilizer in winter, and over-fertilizing can cause fertilizer burn, leading to leaf drop.

Winter Care Methods for Bougainvillea

1. Increase Light Exposure: Bougainvillea needs more light in winter and can be placed near a window indoors, but avoid direct sunlight.

2. Control Temperature: The suitable growth temperature for bougainvillea in winter is between 15-25°C. If the temperature is too low, move the plant indoors and keep it warm.

3. Water Moderately: Bougainvillea requires less water in winter, and the soil should be kept slightly moist, avoiding waterlogging. Watering once or twice a week is generally sufficient.

4. Fertilize Appropriately: Bougainvillea needs less fertilizer in winter and can be given a low-nitrogen, high-phosphorus and potassium compound fertilizer once a month.

5. Clean Diseased Leaves: When leaf drop is noticed, promptly remove the diseased leaves to prevent the spread of disease.

6. Prune Branches: In winter, it's appropriate to prune the branches of bougainvillea, removing dead and diseased branches to promote new growth.

Points to Consider for Winter Care of Bougainvillea

1. Avoid Direct Sunlight: Bougainvillea should not be exposed to direct sunlight in winter to prevent leaf damage.
