Cultivation methods and precautions of flower peony

1. Maintenance methods

1. Temperature: Judging from its origin and distribution area, it prefers higher temperatures, specifically between 20 and 32 degrees. If the temperature is too high, its leaves will easily wither, so it should not exceed thirty-five degrees. Some varieties have good cold resistance and can withstand temperatures as low as minus eight degrees Celsius, but some are also more afraid of the cold.

2. Light: Peonies love light very much, and only need shade when the light is too strong. Generally speaking, there is no need for shade except in summer. In summer, the light cannot be completely blocked, and the shading degree should be kept at around 50%.

3. Watering: Although peony likes moisture, it is also afraid of waterlogging. Therefore, it can be adjusted according to drought and flood conditions. During dry spells, water more often to keep the plants moist. But when there is a lot of rain, we must pay attention to drainage.

4. Fertilization: It has a longer flowering period and more leaves, so it requires more fertilizer. In addition to base fertilizer, try to use liquid fertilizer once or twice a month, especially during the flowering period.

2. Breeding techniques

1. Repotting: Peonies grow faster during the growth period and consume more nutrients during flowering. Therefore, try to change the soil every year. Mountain soil can be used as the main matrix and mixed with materials such as sawdust. In addition, base fertilizer is still relatively important, and available ones include animal manure, cake fertilizer, etc.

2. Pruning: Peonies grow fast, so pruning is very important, and the plants are relatively resistant to pruning. Generally speaking, you can pinch off the tips of the flowers in spring to ensure more flowers bloom later. Before entering winter, it is best to prune, mainly cutting off old and dry branches and leaves.

3. Problem diagnosis and treatment

1. Disease: There is "soot mold", which seriously affects the branches and leaves, especially the leaves, affecting their photosynthesis. Thiophanate can be used for prevention and treatment. There is also "anthracnose", which spreads very quickly and needs to be prevented and treated with Bordeaux in time.

2. Pests: Mainly "nematodes", which harm the roots. It is very important to disinfect the soil.
