Land

The most hospitable soil for peonies is moderately clayey, humus-rich, deep, permeable, and well-drained, sub-acidic and slightly alkaline. Plants should be fertilized at the end of the growing season.

Watering

Plantation

Peonies are planted with about 80 centimeters of space between plants and covering the root ball with a 7-8 centimeter layer of soil. In June, propagation is carried out by layering.

The best time to plant peonies, whether bare-root or in a pot, is from September to the last days of November.

Keep in mind that if you plant too deep, the peony will grow but not flower.

Flowering

The tree peony does not need to be pruned: just remove the flowers and dry leavesThe particular beauty of peony flowers (a genus comprising 25 species) is due to their multitude of colors: white, pink, yellow, red, purple, and violet.
