How to cultivate and maintain white grass in water? How to distinguish between white grass and orchid?

White grass, alias green bamboo, white orchid. It is a persistent root and foliage plant with strong drought tolerance and is suitable for small potted plants for viewing. The white grass is very similar to the silver-edged orchid, but it does not walk the stem. The leaves are delicate and soft, and there are white spots on the green leaves.

1. Hydroponic method

(1) hydroponically cultivated white grass can be washed by root washing method, cut off the overdense root, soak 10min in 0.5%-0.1% potassium permanganate solution, rinse again, plant in a transparent impervious container, fix the root with foaming stone, shell sand, colored stone, etc., add water to about 1prime 2 of the root of the plant, do not flood the whole root, so as to avoid root rot.

(2) the yellow leaves are easy to fall off when the winter temperature is low, which can lower the water level, cut off the yellow leaves and put them in the bright place of the indoor windowsill when the temperature warms up in spring, many new leaves and buds will sprout again. As shown in the picture, it is hydroponically cultured white grass.

two。 Maintenance guide

The main results are as follows: (1) the temperature and light suitable for the growth of white leather is 22-28 ℃. If the temperature is below 15 ℃, it will go into human sleep, and the leaves will gradually turn yellow and wilt. White grass likes to have enough scattered light, and avoid strong direct sunlight in summer.

(2)。 Water-changing white grass is easy to rot at the initial stage of water culture, and it is necessary to change water and remove the rotten roots every day. When the roots adapt to the aquatic environment and no longer rot, change the water every 2-3 days, and change the water 10-15 days after rooting.

(3) the nutrient solution should be added when fertilizing and changing water. When the growth of white leather is relatively rapid, the nutrient solution should be added to provide the nutrition needed for growth. When the summer weather is hot, you can often spray water to the leaves to keep the air moist and clean.

(4) Prevention and control of diseases and insect pests. White grass is resistant to drought and humidity, and there are almost no diseases and insect pests in hydroponics, so it is a standard lazy plant. However, freezing injury can occur when the weather is cold in winter, and the indoor temperature should be kept above 15 ℃. If freezing injury has occurred, the withered leaves can be cut off and the plant can be placed in a warm place.

How to distinguish between White Grass and Cymbidium

White grass and Cymbidium are often mistaken for Cymbidium because their color and plant shape are very similar. However, if you pay attention to the observation, you can tell the difference between the two. Although the leaves of Artemisia mandshurica are similar to those of Cymbidium, the stem will grow away from the root, and there will be plantlets growing on the stem, but the grass does not have this characteristic. The hypertrophic root of white grass is not found in Cymbidium, which is the best sign to distinguish between the two.
