Key points of maintenance of raw grass

There are some special requirements for the maintenance of raw grass. The highlights are as follows:

① high shading: after potted, the raw grass should be placed in the shade for 7 to 15 days, and the degree of shading should be controlled above 80%. More attention should be paid to shading in the early stage of planting.

② must not be too wet: grass planted on the ground should also pay attention to controlling the humidity of the soil. The root of grass is seriously damaged, and those with poor water absorption can take shading, leaf sprinkling, ground sprinkling and other measures to increase air humidity.

③ free fertilizer: no fertilization in the first year, and only appropriate application of thin liquid fertilizer in the second and third years.

④ flower picking: strictly control its flowering in the first year. Flowering will deplete the nourishment of the unhealthy female parent. If there are more flower buds, only 2 flower buds will be retained; the rest will be picked. After flowering, the identification, planting, numbering, recording and photography of the varieties were completed, and the scape could be removed.

⑤ plant protection: in the case of reduced resistance, diseases and insect pests are very easy to spread and spread in the grass, so it is necessary to control them as soon as possible.

Note: novel varieties selected from raw grass are rarely luxuriant and strong, and their plants are often few and weak, so they must be cherished and carefully maintained to ensure their survival, domestication and development. After more than three years of cultivation, most of the roots, stems and leaves are renewed and gradually adapt to the new environment, so they become the so-called "ripe grass".
