What months is the best time to transplant peony flowers
Xiaobian will tell you how the best time for transplanting peony flowers is to introduce green plants in the months. Next, we will share the details.
What is the best time to transplant peony flowers? Mastering these five key points will increase the survival rate by 90%. As a national flower, peony is known as the "king of flowers." For flower lovers who want to transplant peonies, choosing the right transplanting time is crucial. This article will analyze in detail the best time period, operating points and maintenance skills for transplanting peony from a professional perspective to help your peony survive smoothly.
1. Golden time for peony transplanting: From mid-September to late October. After years of horticultural practice, the best time for peony transplanting in most areas of China is concentrated in autumn, specifically from mid-September to late October. This period has three significant advantages: 1. Temperature advantage: At this time, the surface temperature is stable between 15-20℃
The temperature gradually decreases in autumn, but the ground temperature remains within the appropriate range. Monitoring data shows that the soil temperature at a depth of 10cm is usually around 18℃ at this time. Water will not evaporate too quickly due to high temperature, nor will root development be affected by low temperature. 2. Physiological characteristics: pre-dormancy
Peonies begin to accumulate nutrients in autumn to prepare for the winter, and transplanting at this time has less stress on the plants. The root system can still maintain an active period for 2-3 weeks after transplanting, which is conducive to wound healing and new root germination. 3. Climate adaptation: avoiding extreme weather
The precipitation in autumn is moderate, and the air humidity remains in the range of 60%-70%, avoiding the dual threat of cold spring and high temperatures in summer. 2. Guidelines for adjusting geographical differences 1. Northern Region (Northeast, Northwest)
Best window: early September to mid-October
Special considerations: It is necessary to ensure that a rooting period of at least 30 days is reserved before the soil is frozen. It is recommended that no later than October 10 in severely cold areas such as Harbin. 2. Yangtze River Basin
Best window: September 25 to early November
Advantages: The ground temperature in winter is rarely lower than 5℃, and it can even be extended to mid-November in Wuhan and other places. 3. Southern region (Lingnan, etc.)
Alternative: It is recommended to transplant from December to January of the following year
Notes: Avoid the rainy season. Special attention should be paid to selecting planting sites with excellent drainage in Guangzhou. 3. Why is spring not suitable for transplanting? 1. Prominent physiological contradictions
Peony enters the germination period in spring, and transplanting at this time will block the "budd-root" nutrient cycle. Data shows that the survival rate of peonies transplanted in spring is on average 40% lower than that in autumn. 2. Environmental pressure has doubled
The warming process accelerates leaf transpiration, while damaged roots lack water supply. Observations show that the wilting rate of peony leaves transplanted in April is as high as 65%. 3. special case handling
If transplanting in spring is necessary, keep intact soil balls (diameter not less than 2/3 of the plant crown width) and cut off more than 80% of flower buds. 4. Professional transplanting 5 steps 1. Root pretreatment
- Irrigation thoroughly 3 days before seedling raising (soil moisture should be 30-35%)
- Keep the main root more than 30cm, and the cut of the diseased root should be flat
- It is recommended to soak in rooting powder (recommended ABT No. 1) for 30 minutes 2. Preparation for planting acupuncture points
- Excavate 60×60×60cm planting hole
- Lay a 10cm gravel layer on the bottom layer (particle size 1-3cm)
- Backfill soil formula: 50% garden soil +30% leaf soil +20% river sand 3. Planting depth control
- Grafted seedlings: The interface is 3-5cm below the surface
- Divided seedlings: The original soil seal is level with the ground
- Container seedlings: Remove 1/3 of the outer roots 4. Post-colonization treatment
- Build 50% sunshade net for 15 days
- Pour thoroughly root-fixing water for the first time (add 50ppm indole butyric acid)
- Earthing pile height 15cm for overwintering protection 5. Key maintenance nodes
- 30 days after transplanting: foliar spray 0.2% potassium dihydrogen phosphate
- Spring of the following year: postpone the leaf expansion period for 10 days (spray 100ppm paclobutrazol)
- The second year: Strictly control flowers (retain no more than 3 flower buds) 5. Three details to improve survival rate 1. Treatment of variety differences
- Central Plains variety group: relatively resistant to transplanting (for example,'Luoyang Red' has a survival rate of 95%)
- Jiangnan variety group: More soil needs to be brought (it is recommended to keep soil balls with a diameter of 40cm)
- Japanese varieties: Re-cut before transplanting (retain 3-5 main branches) 2. Soil improvement strategies
pH adjustment plan:
- Alkaline soil (pH>7.5): Mix 500g sulfur powder into each hole
- Acidic soil (pH<6.0): Add 2kg of oyster shell powder 3. pest prevention
- Root rot: Soak roots with 50% carbendazim 800 times solution before planting
- Underground pests: Experience in planting holes and applying 5% phoxim granules (20g/hole) shows that peonies that strictly follow the autumn transplanting procedures can have a flowering rate of more than 70% the next year, while plants transplanted in the wrong season often need 3 years to restore flowering ability. It is recommended to combine local phenology observations and find that when the temperature difference between day and night stabilizes at around 10℃ and the ginkgo leaves begin to turn yellow, it is the ideal time to transplant peonies.
