Growth habits of Primrose

Primrose prefers well-drained and humus-rich soil, preferring to be wet. But need to be dry, seedling stage avoid strong sun and high temperature, like a warm and ventilated environment. It can grow well in sandy loam and clayey loam with more humus (pH5.5 to 6.5). In the places where the soil is heavy in the south, it is generally mixed with self-made rotten leaf soil (soil made by collecting leaves and acid soil, chicken dung and charcoal powder). The original clay must be broken before mixing, otherwise it will not play the role of soil improvement.

Propagation methods of Primrose

Primroses are often propagated by seeds, but their seed life is short and their germination ability is lost quickly. If the seeds harvested in spring are sown in autumn, the germination rate will be halved. Therefore, the harvested seeds should be dried and refrigerated to reduce their metabolic activity and prolong their life. Sowing time should be determined according to the required flowering time, winter flowering can sow in late spring, spring flowering can sow in early autumn. Sowing seedlings in late spring will soon enter the hot summer, it is necessary to do a good job in cooling, otherwise the seedlings are very easy to die in the extremely hot weather. A small amount of planting can be sowed in April, and when summer comes, the seedlings have grown up and have strong heat resistance, so they can spend the summer safely in a shady and ventilated place.

Culture methods of Primrose

1. Soil: primroses prefer rotten clayey soil and sandy soil, whose PH value can be kept at about 5.5-6.5.

2. Environment: primroses like warm, ventilated and moist environment, which can properly receive astigmatism and is not suitable for direct sunlight.

3. Watering: Primrose likes a humid environment, but it can't touch too much water, otherwise it will cause rotten roots.

4. Diseases: primroses are mainly leaf and stem diseases. 75% chlorothalonil wettable powder 600: 700 times aqueous solution can be used at the initial stage of the disease, spraying once every 5 to 7 days, several times to control the development of the disease.

5. Pests: the diseases and pests of primroses are mainly red spiders, aphids and other pests, which should be mainly prevented, spraying 3 to 4 times a year, the first before flowering, the second after flowering, and the third from July to August.
