Rhododendrons require well-drained, acidic soil. Give it a certain amount of scattered light every day to avoid exposure to strong light, which may cause the leaves to burn. The temperature should be kept between 15-25℃, not higher than 35℃ in summer and not lower than 5℃ in winter. In daily maintenance, water frequently to keep the substrate moist. Apply cake fertilizer and water every 10 days during the growth period, and topdress every 15 days after flowering. Before winter, add more phosphorus and potassium fertilizers to help it survive the winter safely.

1. Soil

Rhododendron is suitable for growing in acidic soil with good drainage. Alkaline soil in the north needs to be added with a small amount of peat soil. For potted plants, you can prepare your own potting soil, mainly leaf mold soil, with a small amount of sand added to enhance drainage. In addition, a certain amount of cake fertilizer can be added to provide nutrients for its growth.

2. Light

Cuckoo update It likes a well-ventilated semi-shady environment, the light should not be too strong, and it can be placed in a place with scattered light for a long time. Pay attention to shade in summer and avoid strong light exposure, otherwise the leaves will be sunburned and the plant will die.

3. Temperature

Azalea It can grow normally in an environment of 12-25℃. If the temperature is higher than 35℃ in summer, its growth rate will slow down and it will enter a semi-dormant state. Appropriate cold protection measures should be taken in winter to avoid frostbite on plants. The temperature should not be lower than 5℃. When the temperature in the north is too low, place it in a warm place indoors, or cover the plant with a bag to keep it warm.

4. Watering

Cuckoo Flowers have a high demand for water. You cannot wait until the soil is dry before watering. You must keep the substrate moist at all times. Generally, water should be watered once every 2-3 days, and watering should be done every day in summer. Do not use tap water directly, it is best to let it sit for a few days before watering. In addition, the water temperature must be controlled well. If the water is too cold, it will affect the water absorption function of the roots.

5. Fertilization

Fertilizing rhododendrons is usually done in spring and autumn. When entering the dormant period in summer and winter, fertilizers tend to accumulate, causing the fertilizer to be too concentrated. Apply cake fertilizer and water every 10 days during the growing season. Topdress once 15 days after flowering to replenish the nutrients consumed by flowering. Apply more phosphorus and potassium fertilizer before winter to help plants survive the winter.
