Cultivation methods and precautions of Erythrina cockscomb

1. Maintenance methods

1. Soil management: The choice of soil is widely applicable. Generally, sandy soil is used for planting. Soil with good drainage and high nutrients is more suitable for the growth of Erythrina cockscomb.

2. Water management: Erythrina crestina can grow in arid and barren places and can also resist saline-alkali. However, when watering Erythrina crestina, there should be no accumulation of water. Too much accumulation of water will cause its roots to rot and affect its growth.

3. Nutrient management: Apply organic fertilizer before planting, and apply some urea water after planting. The time for urea water irrigation is about 30 days. This can promote the absorption of nutrients by Celosia cresteda and is more conducive to its growth needs.

4. Light and temperature management: Erythrina cockscomb has good adaptability, prefers an environment with high light and temperature, and is also very cold-resistant. It is best grown outdoors in a location with good light, and both full-day and half-day exposure time are possible.

2. Breeding techniques

1. Pruning: When the branches turn yellow or withered, they should be pruned in time, and the pruned branches should be disposed of and buried in time to avoid the growth of their rhizomes affected by pathogens and pests in the branches.

2. Cuttings: Generally, cuttings are used for propagation. Choose strong branches, about 20 to 40 centimeters, and insert them in moist and nutritious soil. They will germinate in about two days and can be transplanted after about 30 to 60 days of cultivation.

3. Problem diagnosis and treatment

1. Skin rot disease: After Erythrina crestina gets skin rot disease, it is very easy to die. At first, it will show external rot symptoms and then slowly expand and grow. At this time, the rotten branches should be cut off in time and the branches can be wrapped with pesticides.

2. Leaf spot disease: Leaf spot disease mainly appears on branches and leaves, and the diseased areas will have gray-black symptoms. At this time, you should use fenpropimorph emulsion to dilute it with water and spray it on the branches of Erythrina crestina.

IV. Other issues

1. How to enter the winter: When winter comes, it should be transplanted indoors for cultivation. The temperature should be above four degrees Celsius. It is best to place it in a well-ventilated and well-lit place. There is no need to water it too much in winter, just keep the soil moist.

2. Whether it can be exposed to rain: On rainy days, the cockscomb erythrina must be drained and dewatered in time. Water must not be allowed to accumulate, as stagnant water will cause its roots to rot.
