Off-season Peony Revitalization Management
Here are some related experiences for everyone on growing peonies at home, including off-season peony revitalization management. The editor will introduce the following to netizens.
Since the promotion of peony flowering during the Spring Festival is an off-season cultivation technique, after the flowers fade, the peony's nutrients are basically depleted, and the newly formed absorption roots are few or even non-existent, which cannot absorb nutrients normally. If continued cultivation, the survival rate and growth potential are not ideal, and the cost of cultivation is high. Therefore, the peony seedlings after flowering can be discarded.
However, if you do not want to give up, you can take the following measures to revitalize. If managed properly, they can continue to survive and even bloom in the future.
1. Post-flowering Seedling Training
Remove the residual buds from off-season peonies after flowering to reduce nutrient consumption. Gradually lower the temperature, frequently ventilate, and gradually extend the ventilation time to enhance the plant's ability to adapt to the external environment. Watering should follow the principle of "do not water when not dry, water thoroughly when watering," to prevent both water shortage and root rot. Additionally, increase top dressing and spray foliar fertilizers.
2. Potting and Transplanting
In April, as the external temperature rises, the plants can gradually adapt to the external environment. At this time, the off-season peony should be repotted, and the original plant can be planted in the ground or continue to be maintained in a pot, but ground planting is more effective. When transplanting, properly prune the plant's branches and leaves, cut off the diseased and weak branches, leaving 4-6 healthy branches per plant, removing 1/3-1/2 of the leaf mass, and also removing diseased and rotting roots to promote the regeneration of new roots, enhance water absorption capacity, and relieve the balance of moisture between the aboveground and underground parts. Apply sufficient base fertilizer when planting and water thoroughly after planting.
Subsequent daily maintenance: Watering should follow the principle of "do not water when not dry, water thoroughly when watering," spray water on the plants once a day on sunny days until before the rainy season. Avoid waterlogging during the rainy season. Fertilization is done through foliar sprays and water fertilization, mainly using fast-acting fertilizers, following the principle of "small amounts multiple times," about every 20 days, and during the rainy season, the fertilizer concentration can be slightly increased, with foliar sprays about every 10 days. During cultivation, timely loosen the soil and remove weeds.
3. Shading for Summer
During revitalization cultivation, due to the weaker plants, it is important to shade the peonies from strong sunlight and high temperatures in the summer. Generally, about 50% of sunlight is needed, and good ventilation must be ensured. As water evaporation is high, watering should be timely, and after each watering, promptly loosen the soil, remove weeds, and pay attention to the prevention and control of diseases and pests. Spray a soilless cultivation nutrient solution once a week, but be sure not to apply top dressing. This is crucial during this period.
4. Management in Autumn and Winter
After the beginning of autumn, temperatures gradually decrease, and rainfall increases, and the roots of off-season peonies grow rapidly. At this time, the concentration of fertilizers for watering can be slightly increased, following the principle of "small amounts multiple times," to promote rapid and robust root growth. Foliar sprays about every 10 days until before defoliation. In mid-to-late September, the shading net can be removed. Before winter, apply a compound fertilizer. During winter, take measures to prevent cold and frost.
5. Revitalization Management in the Second Year
After a year of maintenance and revitalization management, the plant's growth potential gradually recovers by the second spring. After the spring weather warms up, apply fast-acting fertilizers. Begin foliar sprays after the leaves start to unfold, applying thin fertilizers frequently, every 10 days until before defoliation. Also, apply root top dressing once a month. After a year of meticulous cultivation, some plants may have flower buds. To fully restore their growth potential, all flower buds should be removed. Also, pay attention to the prevention and control of peony diseases and pests.
The above comprehensive introduction to off-season peony revitalization management is hoped to provide green plant enthusiasts with some knowledge about green plants.
