1. Suitable temperature

2. Sufficient light

3. High humidity

4. Reasonable fertilization

The flowering period of azaleas is generally between April and May, but with proper care, they can bloom in winter. First, control the temperature of the environment and keep it above 12°C. At the same time, appropriate light should be provided every day, and a plastic bag can be used to cover it when the ambient temperature is low. In addition, watering should be sufficient and spray water appropriately to keep the air moist. In terms of fertilization, topdress once every half month and foliar fertilizer once a week to provide sufficient nutrients.

1. Suitable temperature

Azaleas will enter a dormant state in winter. If they want to bloom, they must provide higher temperatures to allow them to continue growing. The ambient temperature should be controlled at around 15-30°C and cannot be lower than 12°C, otherwise the growth will be slow and not conducive to flowering.

2. Sufficient light

Think For rhododendrons to bloom, they need sufficient light. The daylight hours are shorter in winter, but the lighting is softer, allowing you to be in the sun all day long. Of course, you should also pay attention to heat preservation while lighting. It can be placed on the balcony or windowsill indoors, and it should be covered with plastic bags outdoors to maintain the temperature.

3. High humidity

Rhododendrons have a high demand for water, especially before they bloom. Watering must be adequate. In addition, the ambient humidity should be increased as much as possible, and water can be sprayed around to humidify. The water temperature in winter must be strictly controlled. Cold water will freeze the plants and needs to be close to the indoor temperature.

4. Reasonable fertilization

Winter It is generally not suitable to fertilize, but in order to promote flowering, it needs to be supplemented with certain nutrients. In autumn and winter, you can apply some decomposed organic fertilizer, which should be diluted before use to ensure that it will not damage the roots. After that, top dressing should be done every 15-20 days, using urea and potassium dihydrogen phosphate to supplement various nutrients. In addition, foliar fertilizer can be applied once a week to facilitate absorption. After it blooms, fertilizer must be stopped in time.
