The nutritious soil is made up of loose, well drained and aerated peat, 2:2:1 pond mud, peat soil and coarse sand mixed with a small amount of retting cake fertilizer. The peat is mixed with water (standard of adding water: after mixing with water, hold a handful of peat tightly, and the water seeps out of the finger joint) and wait for the cup to be planted.
For the reused old basin, it must be soaked in 2000 times solution of potassium permanganate for more than half an hour, then washed with water and dried for use. In general, the large potted plants are planted in a 20cm size potted plant. When planting, place a 4cm substrate on the bottom of the cup first, and then move the screened seedlings into the cup. The planting of the small seedlings should not be too deep, and it is better to flat the base of the plant. The substrate should be moderately tight, and be filled until the cup is 8 points full, 2-3 plants /pot.
Dishui Guanyin is particularly fond of humidity. In the growing season, not only the basin soil is required to be wet, but also the air humidity is required to be no less than 60%. In summer, when the temperature is high, it is necessary to strengthen water spraying to create a relatively cool and humid environment for it, which is placed in the indoor air-conditioning hall, not only to ensure that the basin soil is wet, but also to spray water on the leaves from time to time. If the room temperature can not reach 15 ℃ in winter, watering should be controlled, otherwise it will easily lead to rotten roots of plants. In general, spraying warm water once a week can keep the leaves green.
Dishui Guanyin prefers to be fat. From March to October, the liquid fertilizer should be applied every half a month, in which the proportion of nitrogen element can be increased appropriately. If a little ferrous sulfate can be added, the leaves will grow as large as lotus leaves, bright and clean. Fertilization should be stopped when the temperature is lower than 15 ℃.
Dishui Guanyin is a foliage plant. If the zhongzhiyang lake is not suitable, its biggest leaf will turn yellow and dry. At this time, it should be removed together with the stem, otherwise it will affect the growth and ornamental of other leaves.
You can use rotten leaf soil, peat soil, river sand and a small amount of cake fertilizer to mix the nutrient soil. In addition, you can also hydroponics, but you should pay attention to prevent rotten roots and add nutrient solution. Generally, the basin is changed once a year in spring, and the basin soil can be loosened once a month to keep it in a good state of permeability.
