How Much Space is Needed for Planting Peonies
As the king of flowers, the cultivation of peony requires careful planning. Planting spacing not only affects the growth trend of the plants but also directly relates to the quality of flowering and land utilization. Scientific and reasonable cultivation distances can avoid root competition and create a beautiful landscape effect, which is a key element for successful peony planting.
Seedling Age Grading Management
1-2 Year Old Seedling Cultivation
New seedlings are usually less than 30cm tall, with roots not fully spread out. Using a dense planting mode of 20cm×50cm ensures that each seedling gets 4.5㎡ of growing space while increasing the seedling rate per unit area. Pay attention to diagonal offset planting to form a diamond-shaped layout that allows for ventilation and light.
Three-Year Old Strong Seedlings Formation
When the main stem diameter reaches 2cm, it is necessary to expand to a spacing of 40cm×50cm. At this time, the horizontal expansion range of the roots reaches 60cm, maintaining a leaf opening angle of 25-30° to ensure each plant gets 6-8 hours of direct sunlight.
Adult Plant Optimization and Adjustment
Five-year-old plants can have a crown width of up to 80cm, using a dynamic adjustment strategy: initially planted at 50cm×60cm, and in the third year, every other plant is transplanted to form a permanent spacing of 1m×1.2m. Combined with organic base fertilizer applied in furrows, a 30cm operating passage is reserved between rows and plants.
Functional Zoning Design
Production Planting Density
Commercial cultivation uses a 50cm×60cm matrix, combined with a drip irrigation system to form planting zones. Control 18,000-20,000 plants per hectare, and update the planting area every 5 years through a crop rotation system to maintain soil fertility balance.
Landscape Aesthetic Layout
The observation area implements a 1m×1m square planting, combined with terrain undulations to create a three-dimensional sea of flowers. It is recommended to interplant early, middle, and late flowering varieties to extend the viewing period. Key areas can be expanded to 1.2m spacing, reserving space for photography.
Scientific spacing planning needs to be carried out in conjunction with soil improvement, it is recommended to deeply turn the soil by 60cm three months before planting, mixing in decomposed manure. Regularly monitor the microclimate between plants, and thin out branches when the relative humidity is consistently above 75%. Mastering these techniques will help cultivate high-quality peonies with beautiful shapes and vibrant flowers.
