Evening primrose cultivation methods and precautions

How to grow evening primrose

illumination

Evening primrose likes light and is suitable for cultivation in a ventilated and bright place in the courtyard. It can also be grown on the balcony to absorb sunlight every day.

Fertilization

During the growth period, apply liquid fertilizer 1-2 times a month. Nitrogen fertilizer is mainly used during the growth period, and phosphorus and potassium fertilizers are mainly used during the bud formation period.

Watering

Evening primrose is relatively drought-resistant but not water-resistant. Water it in time when the soil surface is dry. After each watering, tillage and weeding should be carried out in time to facilitate moisture conservation and ventilation, and promote the healthy growth of the plants.

soil

Evening primrose is not very demanding in terms of soil. Generally, neutral, slightly alkaline or slightly acidic soils are acceptable. It grows best in sandy loam with good drainage, looseness and fertility.

Precautions for evening primrose cultivation

Pinching after planting

If the evening primrose is transplanted from somewhere else, it is necessary to pinch the tops of the plants after they have been established to promote branching and dwarfing of the plants and increase the amount of flowering.

Can overwinter in the open in the south

Evening primrose is relatively cold-resistant and can overwinter in the open field in warm areas of the Yangtze River Basin. However, if the temperature in northern regions is too low, it must be transferred to a greenhouse for cultivation.

Fertilize during flowering period

During the flowering period of evening primrose, use dilute human urine, or liquid fertilizer made from fermented bean cake, rapeseed cake, or colored bones, diluted with 9 parts of water, and apply once every 3-4 days.

October is suitable for sowing

Evening primrose is generally suitable for sowing in October. When winter comes, the seedlings should be transferred indoors for wintering and then transplanted in spring.

Biennial cultivation produces more flowers than annual cultivation.
