Growing azaleas requires soft light, but avoid strong light. The soil is prepared by mixing leaf humus soil, sandy soil, etc. Watering should be based on seasonal changes, once every two days in spring and autumn, watering every day in summer, and then watering when it is dry in winter. Fertilizer is mostly applied after the flowering period, and top-dressing is sufficient every 15 days. Propagation is generally based on cuttings. If you encounter pests and diseases, you need to remove the diseased leaves and pests, and then use drugs to control them.

1. Breeding methods

1. Breeding methods

1. Sunlight: Rhododendrons are not suitable for exposure to sunlight, but they can grow under scattered light. Excessive sunlight can cause leaf burns, leaf edges withering, and death. Therefore, it must be shaded in time at noon in summer, or placed in a semi-shady place.

2. Soil: Rhododendron has certain requirements for soil. In addition to good drainage, it is best to be acidic. Generally, a mixture of humus soil and sandy soil is used, and a small amount of cake fertilizer is introduced as the base fertilizer.

3. Watering: The azalea cannot be watered dry. It should not be damp, just keep the soil slightly moist. Generally, water every two to three days in spring and autumn. It needs to be watered every day in summer, and in winter it needs to be completely dry before watering. Water quality must also be strictly controlled. It can be acidified with ferrous sulfate or vinegar before use, and the temperature should be close to room temperature.

4. Fertilization: Fertilizing rhododendrons is very demanding. In early spring, organic fertilizer can be added to the flowerpot as a base fertilizer. After the flowering period, topdress every 15 days. When the branches stop growing, you can stop fertilizing. Topdressing once in autumn is beneficial to overwintering, but it is not advisable to fertilize in winter.

2. Reproduction skills

Cuckoo There are many ways to propagate flowers, including cuttings, grafting, layering, division and sowing. Cuttings are the most common and are mostly carried out in May-June. Select the current year's branches, cut out 10 cm segmented segments, keep the top 3-4 leaves, and remove all the rest. Insert the cuttings 3-4 cm into the pot soil, compact and water thoroughly, wait for them to take root and then transplant.

3. Pest and disease control

1 , Diseases: root rot, brown spot, black spot, etc. Infected branches and leaves should be pruned and sprayed with chemicals to prevent recurrence.
