Cultivation methods and precautions of peony

1. Maintenance methods

1. Temperature: It has a very strong adaptability to temperature. In winter, it can withstand temperatures as low as minus fifty degrees Celsius. In summer, if the temperature reaches 38 degrees, it will not affect its normal growth and flowering. However, the most suitable temperature is between fifteen and twenty-five degrees.

2. Light: It prefers sunlight. Generally speaking, when it is growing fast and before and after flowering, it needs to be placed in a sunny location so that it grows well and blooms more. However, it needs to be placed in a shaded location in summer, as too strong light will burn its leaves.

3. Watering: It likes moisture, but too much waterlogging will have adverse effects. During the growing and flowering periods, it needs to be slightly moist. However, water must not accumulate and drainage is required during the rainy season. Furthermore, when the temperature is low, do not water too much.

4. Fertilization: Pay attention to the richness of nutrients. Generally speaking, the best ratio of nitrogen, phosphorus and potassium is two to two to one. In addition, it is best to water after fertilizing.

2. Breeding techniques

1. Reproduction: The material used for the reproduction of peony is its foot bud root segment. The foot bud refers to its white fleshy rhizome. These can be found in the soil layer thirty centimeters below the ground. It can be done in spring and autumn, and after digging them out, they can be planted. Some base fertilizer needs to be mixed into the substrate in advance. After planting, keep the temperature suitable and it will germinate in about ten days.

2. Pruning: The most important thing is pruning after flowering. Because the dry branches left after flowering will be very long, affecting subsequent growth. In addition, diseased, insect-infested, and redundant lateral branches need to be pruned in time to prevent them from affecting the overall health.

3. Problem diagnosis and treatment

1. Disease: There may be the harm of "root rot", which is most likely caused by too much watering. It can be controlled by carbendazim and oxadiazon. There are also "leaf spot disease" and "brown spot disease", which can be treated with chlorothalonil.

2. Pests: In summer, there are many pests. For example, there are "termites", "grubs", "leaf rollers", etc. You can spray some insecticides regularly for prevention and control.
