Cultivation methods and precautions of American dianthus

1. Maintenance methods

1. Light: It likes to stay in the sun, so be sure to give it enough sunlight. When the temperature is high, provide shade for it to avoid direct sunlight.

2. Temperature: The most suitable temperature is 15~20 degrees Celsius. When the temperature is high in summer, the temperature should be lowered. When the temperature is low in winter, it should be placed in a greenhouse and kept above 12 degrees Celsius.

3. Water: It does not require much water. You do not need to water it every day. Just water it when you see the soil is dry.

4. Nutrients: There is no need to fertilize frequently. Apply enough base fertilizer when planting. In the future, you only need to fertilize it at critical times such as when flower buds are formed. Generally, organic fertilizer is used.

2. Breeding techniques

3. Problem diagnosis and treatment

1. Bacterial spot disease: Long gray-brown spots will appear on the leaves, rhizomes and petals. In severe cases, the leaves will turn yellow and fall off. If the disease is discovered, the humidity should be reduced in time and streptomycin sulfate should be sprayed for prevention and control.

2. Brown spot disease: Brown spot disease mainly harms its leaves, pedicels, and rhizomes. Circular spots appear in the early stage of the disease, and there are brown rings around the spots. When the disease is serious, the leaves dry up and the flowers wither. When the disease is found, spray benomyl in time.
