Konjac with cat's eye is originated from the tropics and subtropics. It is suitable for growing at 20-30 ℃. The growth temperature in winter should be kept at about 16 - 18 ℃.
Shade tolerant plants, like half shade, should be placed in bright indoor light. Avoid direct sunlight, exposure, etc. to avoid burning leaves. Shade and ventilate well in summer.
In the growth period of the catnip, it is necessary to fully water the pot soil to keep it moist. At the same time, it is also necessary to avoid water accumulation in the soil, so as to prevent rotten roots and even death of plants. Because the leaves are large and the water evaporates quickly, the air humidity around them should be kept high. Spray can often be carried out to the blades to keep the surrounding air moist, which is conducive to the growth and extension of its leaves. Once it is found that the leaves are curly and atrophic, it means that the plants are in a state of water shortage.
Follow the principle of "diligent and thin". In winter dormancy period and summer continuous high temperature, stop fertilization.
Every other year change basin once, should choose fertile, loose, good permeability and drainage, contains rich humus micro - acid soil.
The common pests are mainly scale insects and spider. According to the disease situation, the scale insects can be sprayed with 1000 fold solution of 40% Omethoate, 1000 fold solution of 50% dichlorvos and 3000 fold solution of 2.5% deltamethrin. For the red spider, it can be controlled during the adult period after hatching. It can be killed with 1000 times of 20% dicofol emulsion or with 1000 times of 40% Omethoate emulsion.
The common diseases are mainly white silk disease and leaf spot disease. For the white silk disease, we can add 70% pentachloronitrobenzene of 0.2% of the soil weight to disinfect the soil, remove the diseased plant and soil, add new soil, and do well in ventilation. For leaf spot disease, it is necessary to remove the diseased leaves in time, increase the base fertilizer and enhance the disease resistance.
