Can peony flowers be transplanted in spring?
Peony, known as the "national beauty and fragrance," has a direct impact on plant survival and flowering quality. Every spring, many flower friends ask about peony transplanting. This article will provide an in-depth analysis of the prime time and matters needing attention for peony transplanting to help you master the cultivation secrets of this rich flower. 1. Analysis of the best transplanting time of peony flowers 1.1 Three major advantages of autumn transplanting The golden period for peony transplanting is from the beginning of September to mid-October of the lunar calendar (9th to October of the Gregorian calendar). At this time, the plant is in a semi-dormant state, and the root system can quickly repair damage in the soil environment of 15-20℃, and can resume growth vitality after the temperature rises the following spring. Transplanting at this time can make full use of the winter dormancy period to complete root reconstruction and avoid nutrient consumption. 1.2 Potential risks of spring transplanting The growth characteristics of peony that "root roots in spring and cultivate roots in autumn" put spring transplanting at risk of root damage. At this time, the plant is in the germination stage, and transplanting may easily cause new buds to wither and flower buds to fall off. Data shows that the survival rate of transplanting in spring is about 40% lower than that in autumn, and it takes 2-3 years to restore flowering ability. 2. Spring Emergency Transplanting Operation Guidelines 2.1 If spring transplanting is necessary, complete soil balls with a diameter of more than 30cm must be retained. During operation, the soil balls are first wrapped with straw ropes and then wrapped with linen to ensure that the roots maintain close contact with the native soil during transportation and maximize the protection of capillary roots. 2.2 Apply 5kg of decomposed sheep manure to the bottom of the transplanting hole at the key point of nutrient supply, and fully mix it with the surface soil. After planting, watering rooting agent solution (diluted at a ratio of 1:800), combined with foliar spraying potassium dihydrogen phosphate solution (concentration of 0.2%), once a week for 3 consecutive weeks. 2.3 After the three elements of water management are irrigated with root-fixing water for the first time, the soil moisture is maintained at 60%-70%. Use the dipping basin method to replenish water to avoid water flow impact and damage to the root system. In the rainy season, timely drainage is needed to prevent root rot caused by stagnant water. 3. Maintenance and management after transplanting Build a 50% sunshade net for 2 weeks after transplanting and gradually increase the light intensity. Remove the current season flower buds in time to concentrate nutrients to promote root development. Before germination in spring the following year, organic fertilizer is applied to circular ditches to supplement nutrients.
Mastering the principle of "autumn planting and spring cultivation" for peony transplanting, combined with scientific soil transplanting techniques, even emergency transplanting in spring can achieve a high survival rate. It is recommended that flower friends follow the laws of nature as much as possible so that this "king of flowers" can complete the perfect transition of its life cycle at the most suitable time.
