This kind of flower is as white as jade when it blooms.

Jade hairpin, I guess a lot of flower friends are not common. It is a fragrant flower, white as jade, fragrance floating a few miles, is a very suitable for decorating the courtyard, or placed in front of the window table a few potted plants. As long as the hairpin blooms, it is full of branches in strings, and the color is the most provocative.

Generally planted hairpin, flower friends had better choose earthen pots, pottery pots, generally about 20 cm in diameter flower pots. Hosta is a deep, well-drained, fertile sandy loam. Flower friends can use fine sand or moldy soil: sand according to 3:2 preparation, or garden soil: humus soil: river sand according to 5:4:1 mixture.

To plant the hairpin, first put a tile on the seeping place of the flowerpot, then spread a layer of culture soil, and then put the plant into the pot. The planting depth should be moderate, the roots should not be exposed in the shallow, and the heart should not be buried deeply. After planting, pour water once and put it in the shade to slow down the seedlings.

The maintenance of Hosta requires that fertilization should follow the principle of "light fertilizer, frequent application, small amount and complete nutrition". In the germination period, nitrogen-based fertilizer should be applied; in the budding period, phosphate-based liquid fertilizer should be applied.

From the beginning of bud germination, nitrogen and phosphorus combined with thin liquid fertilizer every 2 to 3 weeks, after summer to apply phosphorus and potassium fertilizer mainly, which can promote flower bud differentiation, but also can maintain pure flower color. Flowering should stop fertilizing. After autumn, continue to apply liquid fertilizer until the ground part withers and then stop, so as to ensure that the roots absorb enough nutrients, greatly enhance their cold resistance, but also conducive to their growth in the coming year.

Hosta likes moisture and cannot tolerate drought. Pay attention to watering during growth, but it should not be too dry, but it should not be excessive and produce ponding. Too much ponding can easily cause death of Hosta. Watering time is generally best at sunrise, and leaves should be kept dry at night to prevent disease. If watering at sunset in the evening, spray some fungicides.

Do not water flowers at noon at high temperatures, otherwise it is easy to cause burns and diseases. Watering should be uniform and consistent to prevent local dryness and dampness, which may cause root diseases. Water after each application.

Hosta prefers bright light. In spring, autumn and winter, because the temperature is not very high, it can accept direct sunlight, which is conducive to photosynthesis and flower bud formation, flowering and fruiting.

In summer high temperature weather, to carry out appropriate shade, shade degree in 50%, otherwise, the plant receives direct sunlight, growth is very slow or enter a semi-dormant state, and leaves will be burned and slowly yellow, fall off. When placed indoors, try to place it in a bright place.

Hosta likes warm climate, but summer high temperature, sultry, especially in the temperature above 35℃, and air relative humidity above 80% environment is not conducive to plant growth. At this time, it is necessary to strengthen the air circulation to facilitate its transpiration, help it reduce the temperature in the body, and also spray the foliage to cool down. Winter temperature requirements are very strict, the temperature must be above 10 ° C, otherwise below 10 ° C, it will stop growing, in the frost can not safely winter.

The flowering period of hairpin is from July to September. Before flowering, phosphorus and potassium fertilizer can be sprayed, which can make the plants bloom beautifully. After flowering, the light can be shortened appropriately, which can prolong the flowering time. It can also be cooled appropriately to prolong flowering.
