The potted plant of peacock and taro is suitable to use loose, fertile, well drained and humic loam. Generally, it can be mixed with 3 parts of rotten leaf soil, 1 part of peat or sawdust, 1 part of sand, and a small amount of soybean cake as the base fertilizer. Do not use heavy Garden soil. When the basin is on, the basin bottom is first padded with 3cm thick coarse sand as a drainage layer to facilitate drainage.
In the growth period, sufficient water should be given, especially in summer and autumn, in addition to keeping the basin soil moist, water should be often sprayed on the leaf surface to cool down and moisturize; it requires high air humidity, preferably 70% to 80%; air drying and basin soil drying should be avoided, but water should not be accumulated. After the end of autumn, water should be controlled in order to survive the cold. In winter, it keeps dry environment. If it is too wet, its basal leaves will be scorched, which will affect its ornamental value.
During the growth season from May to September, it should be placed in the shade or semi shade, with a light transmittance of 40% - 60%, avoiding direct sunlight. Excessive light or air drying will easily cause the leaf tip to be scorched and the leaf surface to be dark; however, the light should not be too weak. If it is placed in the dark room for a long time, the temperature is low and the light is insufficient, it will also grow weak, which is unfavorable to the formation of leaf color and lose the unique metal luster of the leaf surface. Direct sunlight through glass is acceptable in winter.
When malachite and taro were short of fertilizer, the plant was obviously short, the leaf color was dim, and the golden luster was not brilliant. In the growth period, the application of thin liquid fertilizer once every 20 days, the ratio of N, P and K should be 2:1:1, which can make the leaves bright and bright, and avoid excessive proportion of nitrogen fertilizer. For example, the application of 0.2% liquid fertilizer directly on the leaves every 10 days is extremely beneficial to germination and growth, and the rotation of fertilizer should be stopped in winter and summer.
The root of konjac is shallow, so it is better to choose a shallow basin with a large mouth, which will not affect the growth of the root, and the leaves will not appear heavy in the daytime. The basin soil is loose, permeable, well drained and nutritious.
In spring, the pot of konjac should be changed once every 1-2 years. When the pot is changed, a new culture soil should be added, and the residual roots and leaves should be cut off and replanted for growth.
There are few diseases and insect pests on konjac, but if the ventilation is poor and the air is dry, the scale insects will also occur. Imidacloprid series of drugs are used for spraying control.
