How to raise Hongyun Dangtou

1. Breeding environment

1. Soil: Use breathable, loose and well-drained soil for breeding.

2. Watering: It likes a humid growing environment. To ensure sufficient water, it can be watered every 5-7 days. After entering autumn, its growth will become slow. At this time, you must control the amount of watering. Just keep the soil in the pot moist. There must not be water accumulation to avoid root rot.

3. Fertilization: Apply liquid fertilizer once every 10-20 days during the growing season. You can use fermented cake fertilizer. When fertilizing, do not spread the fertilizer into the leaf tube, otherwise fertilizer damage will occur. No fertilizer is required during flowering and dormant periods.

4. Light: Give it about 10 hours of light and a ventilated environment every day, it will grow better and the color will be brighter.

2. Breeding Methods

1. Propagation by division: April is the best time to do this. First take out the mother plant, break off the new buds, and then cut the wound to keep it smooth, which is more conducive to rooting. Disinfect it, coat it with wood ash, place it in a ventilated place to dry and plant it. No need to water it, just leave a layer of water on the surface of the soil in the pot. It will take root in about 20 days in a ventilated place.

2. Seeding propagation: The temperature should be controlled at 16℃ during sowing. After sowing, cover with film to keep moisture. Then control the temperature at 25-30℃. Seedlings will grow in about a month. When the seedlings are 4cm long, they can be transplanted. As they continue to grow, they can be transplanted.

3. Common pests and diseases

1. The most common disease is Fusarium, which can be controlled by spraying with thiophanate-methyl when discovered.

2. Common insect pests include red spiders and scale insects. If it is red spiders, you can use dicofol to prevent and control them, spraying once every half a month; scale insects can be controlled by spraying a mixture of dichlorvos and malathion, spraying once a week.
