1. Planting method of fragrant snowball seeds

Fragrant snowball seed, cuttage propagation can be, but generally multi-seed propagation. In northern China, spring sowing is more common, usually in March in greenhouse seeding seedlings, fragrant snowball seeds germinate faster than ordinary flower seeds, emergence neatly, germination temperature is 20℃, about 5 days to emerge, 3~4 true leaves planted on the pot, June flowering. To summer hot when poor growth, flowering few, at this time to cut off the flowering, strengthen fertilizer management, autumn and can bloom again. North China and South China are mostly autumn sowing, winter in cold bed protected areas, pot or planting in March of the following year, flowering in April.

Temperature:

The optimum temperature for cuttings rooting was 18℃~25℃, lower than 18℃, cuttings rooting was difficult and slow, higher than 25℃, cuttings were easily infected and rotted, and the higher the temperature, the greater the proportion of rot. After cutting encounter low temperature, insulation measures are mainly used to cut the pot or container wrapped with film; cutting temperature is too high temperature, cooling measures are mainly to cut shade, to cover 50~80% of the sun, at the same time, to cut spray, 3~5 times a day, sunny temperature higher spray times are more, rainy days lower temperature is larger, spray times are less or not spray.

Humidity:

The relative humidity of the air must be maintained at 75 - 85% after cutting. The humidity can be increased by spraying cuttings 1 to 3 times a day. The higher the temperature in sunny days, the more the number of spraying times. The lower the temperature in rainy days, the less or no spraying times. However, excessive spraying, cuttings are easily infected and rotted by germs, because many kinds of germs exist in water.

Light:

Cuttage propagation can not be separated from sunlight, but the stronger the light, the higher the temperature in the cuttings, the more vigorous the transpiration of cuttings, the more water consumed, which is not conducive to the survival of cuttings. Therefore, after cuttage, the sun must be blocked by 50~80%. After the root system grows out, the shading net is gradually removed: the shading net is removed at 4:00 p.m. every day on a sunny day, and the shading net is covered before 9:00 a.m. the next day.

Potting or transplanting:

When the seedlings are potted, first put 2~2 cm thick coarse grain matrix or ceramsite into the bottom of the pot as a filter layer, sprinkle a layer of fully decomposed organic fertilizer as a base fertilizer, the thickness is about 1~2 cm, and then cover a layer of matrix, the thickness is about 1~2 cm, and then put in the plants to separate the fertilizer from the roots to avoid burning the roots.

Second, what is the value of fragrant snowballs

Fragrant snowball plant short and multi-branched, pale purple or white petals, and send out bursts of fragrance, attracting a large number of bees, is an excellent arrangement of rock garden flowers, flower beds, flower border excellent border materials, potted ornamental is also very good.
