Cultivation methods and precautions of Rhododendron tubulosa

Cultivation method of Rhododendron tubulosa

soil

Rhododendron tubulosa is most afraid of alkaline soil. It is necessary to choose acidic soil with good air permeability and rich in humus. If it is cultivated in alkaline soil, it will lead to poor plant growth and even death in severe cases.

illumination

Azalea tubulosa likes light but is afraid of scorching sun. It likes ventilation but is afraid of strong wind. When planting and maintaining it indoors, try to place it in a sunny and ventilated place. It is best to keep the ambient temperature between 18-22.

Watering

Azalea likes moist soil. The soil in the pots indoors is often wet but not dry, so watering must be strictly controlled. If you find that the young leaves are slightly wilting, it means that the soil in the pot is short of water. At this time, you can spray water on the leaves first, and then water the roots. In winter, spraying water should be the main method, with watering as a supplement.

Fertilization

In order to maintain the acidity of the soil, it is necessary to apply some alum fertilizer water on a regular basis, or you can also add a small amount of ferrous sulfate to the water. When repotting the plant, you can add an appropriate amount of slow-release fertilizer.

Precautions for breeding Rhododendron tubulosa

The watering of Rhododendron tubulosa is different in four seasons. In winter, it is better to keep the soil on the dry side, and in summer, it is better to keep the soil on the moist side. The plants grow vigorously in spring and autumn, so watering is required sufficient but not excessive.

If you use tap water to water the tubular azalea, it is best to let it dry in the sun for a day or two first. Do not water it when the soil is not dry, and when you do water it, make sure it is watered thoroughly.
