Solution of peony not flowering

Inappropriate environment, insufficient nutrients, soil problems, pests and diseases, too dense planting, variety problems, improper rooting time and too deep planting.

1, unsuitable environment. Peony likes sunshine. If the light in the growing environment is insufficient, it will affect flowering. Choose a place with sufficient sunshine and good ventilation, maintain proper humidity, avoid excessive watering, and prevent diseases caused by excessive soil moisture.

2. Insufficient nutrition. Paeonia lactiflora needs enough nutrition to maintain its growth and flowering. If the soil lacks nutrients, it will lead to no flowering. Fertilization should be carried out frequently, especially phosphorus and potassium fertilizer, and organic fertilizer can be used to improve soil nutrients.

3. Soil problems. Loose and fertile sandy soil with good drainage should be selected to avoid water accumulation in the soil and affect the root respiration of Paeonia lactiflora.

4. Effects of pests and diseases. Paeonia lactiflora is susceptible to diseases and insect pests, such as rust, anthracnose and aphids. Preventive measures should be taken in time and the equipment condition should be checked regularly.

5. The planting is too dense. Too close planting of Paeonia lactiflora will affect ventilation and light, thus affecting flowering, so the planting density should be adjusted appropriately.

6. Variety problem. Some varieties of Paeonia lactiflora have difficulty in flowering or short flowering period, and may not bloom. Varieties suitable for local environment and planting conditions should be selected.

7. Improper rooting time. The best time for Paeonia lactiflora to propagate by dividing roots is in late autumn, and dividing roots in spring will affect the plant's absorption of nutrients and lead to no flowering.

8. Planting is too deep. When planting Paeonia lactiflora, the thickness of covering soil should not exceed 5 cm of root system, otherwise it will affect the growth and flowering of plants.
