1. Sunshine and temperature: Peony likes plenty of sunshine and needs at least 6 hours of direct sunlight every day. At the same time, peony flowers also have certain requirements on temperature, and the suitable growth temperature is 15-25 degrees Celsius. When the weather is hot in summer, you can consider shading or moving seedlings to the shade to avoid overheating and leaf burns.
2. windproof and ventilation: peony seedlings need to maintain a stable environment during their growth to avoid being attacked by strong winds. You can choose a relatively sheltered garden for planting, and take appropriate shelter measures when the wind is strong. At the same time, it is also important to keep ventilation to prevent water retention and germ growth.
3. Suitable soil: Peony likes loose, fertile and well-drained soil. When planting seedlings, appropriate amount of humus soil or decomposed organic fertilizer can be added to the soil to improve the water retention and fertility of the soil. At the same time, it is necessary to avoid excessive humidity and stagnation of the basin soil and prevent root rot.
4. Proper fertilization: Peony flowers need proper nutrient supply in the growth period and flower bud differentiation period. Fertilization can choose organic fertilizer or compound fertilizer, but pay attention not to be too high, so as not to burn roots or flower buds. Fertilization time is generally in early spring and late autumn.
5. Flower bud management: The flower buds of peony flowers are generated in autumn, so special attention should be paid to protecting the flower buds from accidental injuries. In winter, seedlings can be covered with heat preservation materials or plastic films to avoid low temperature injury and freezing injury.
6. Pest control: Peony flowers are prone to some pests and diseases, such as gray mold, anthracnose and aphids. You can check the status of seedlings regularly, and take corresponding prevention and control measures in time when you find pests and diseases, such as spraying appropriate pesticides or using biological control methods.
In a word, the maintenance of peony seedlings needs to pay attention to sunshine and temperature, wind and ventilation, soil conditions, fertilization, flower bud management and pest control. Only by giving the seedlings a good growth environment and proper care can we ensure the healthy growth and beautiful bloom of peony flowers.
