The suitable temperature range is from 12 ℃ to 25 ℃, and the best temperature in winter is above 5 ℃.
It is suitable for growing on loose and deep humus soil.
In order to improve the air humidity, create a cool environment, and facilitate its growth and development, water should be sufficient in summer and in spring and summer.
The watering should be reduced after late autumn and controlled in winter, so as to keep the basin soil dry.
During the growth period of Hewang orchid, it is required to apply thin fertilizer once a half month.
For home breeding, it is best to irrigate fermented rice washing water or soybean soaking liquid.
0.5% superphosphate can be added into the fertilizer solution from the formation of flower stem to the full flowering stage, which will make the flower color more colorful.
Hewanglan has thick fleshy roots, developed roots and fast growth, so we need to change pots in time.
Hewanglan usually does not seed, and it can do so by artificial pollination. The seeds mature in three months, and are sown immediately after seed collection. The seeds germinate in two to three weeks under the temperature of 25 ℃ to 30 ℃, and the seedlings can blossom after three years.
Generally, it can be carried out in spring and autumn. The method is to buckle the seedling basin upside down, cut it from the root neck with a knife, and smear grass ash on the incision to prevent mildew. To reproduce in ramets, it is required to keep 2 to 3 buds per plant, so that it can bloom in the same year.
I'm afraid of strong sunlight and cold, so I need to keep warm for her.
Hewanglan is a fleshy root, afraid of waterlogging and drought. If the basin soil is wet for a long time, it is easy to cause root rot. therefore, watering should be dry and wet. In addition to sufficient watering in summer and flowering period, watering should be properly reduced in early spring and controlled in winter when the room temperature is low.
In summer, it is necessary to spray water on the leaf surface and the surrounding ground 1 to 2 times a day to improve the air humidity and reduce the temperature.
It should be properly shaded to avoid direct sunlight, otherwise it will burn the leaves.
The suitable temperature for growth is 18-24 ℃. When the temperature is over 32 ℃, spray water to cool down.
