Winter flowering management of azalea, management matters during the flowering period of azalea

1. Suitable temperature

Rhododendrons go dormant in winter, and if you want them to bloom you must provide a higher temperature so they continue to grow. The ambient temperature should be controlled at around 15-30℃ and should not be lower than 12℃, otherwise it will grow slowly and be unfavorable for flowering.

2. Sufficient light

If you want azalea to bloom, it needs plenty of light. The daylight hours are shorter in winter, but the light is milder and you can stay in the sun all day. Of course, you also need to pay attention to heat preservation while exposing it to light. It can be placed on the balcony or windowsill indoors, and covered with a plastic bag outdoors to maintain the temperature.

3. High humidity

Rhododendrons have a great demand for water, especially before flowering, so they must be watered sufficiently. In addition, the ambient humidity should be increased as much as possible, and water can be sprayed around to increase the humidity. The water temperature in winter must be strictly controlled. Cold water will freeze the plants. It needs to be close to the indoor temperature.

4. Reasonable fertilization

It is generally not advisable to apply fertilizer in winter, but in order to promote flowering, it is necessary to supplement it with certain nutrients. In autumn and winter, you can apply some decomposed organic fertilizer. Dilute it before use to ensure that it will not damage the roots. After that, top dressing should be applied 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, be sure to stop fertilizing it in time.
