How to cultivate the grass

1. Maintenance methods

1. Temperature: Ornamental grass likes warmth. Specifically, the most suitable range is between 15 and 25 degrees. In summer, it does not like hot and stuffy environments, so the ventilation conditions in summer must be good. In winter, although it has a certain degree of cold resistance, the temperature cannot be too low.

2. Light: It has certain requirements for sunlight, but it also has a certain degree of shade tolerance. However, during the flowering period, it cannot be placed in a very dark place, otherwise flowering will be hindered. Generally speaking, you can always place it where there is diffuse light. In summer, when there is strong light, it needs to be shaded.

3. Watering: The sedge is afraid of waterlogging and has a certain degree of drought resistance. Therefore, the principle to follow when watering is "better dry than wet", but you must not go without watering for a long time. In summer, considering that evaporation will be higher, you can water a little more.

4. Fertilization: The demand for fertilizer of the orchid grass is relatively high. During periods of vigorous growth, fertilizer should be applied regularly. Generally speaking, foliar fertilization is used once every ten days.

2. Breeding techniques

1. Reproduction: Natural sowing can be used, but it will take a long time from sowing to growing true leaves. The specific steps are: collect the fruits and then take out the seeds. Then sprinkle on the substrate. During this period, do not let them get exposed to rain. It will take about three months for true leaves to grow. Providing a good environment will have an impact on the germination rate.

2. Pruning and weeding: First of all, when you find dry and yellow leaves, be sure to cut them off. The next thing is to prune the flowers, mainly after they bloom. In addition, when weeds appear in the fields, they also need to be cut off.

3. Problem diagnosis and treatment

1. Disease: Common types include "rust", which harms the leaves and also affects the overall growth. Mancozeb can be used for prevention and control. There is also "white rot", which is more common during the rainy season. Lime can be used to disinfect the soil.

2. Pests: "Scale insects" are the most common type of pests. They can also spread other diseases, which can be controlled by spraying with omethoate.
