Emerald breeding and cultivation in the north

The emerald is a perennial evergreen plant with thick leaves and crystal clear green, air roots on the stem sections, and climbing nature. Since it is a tropical plant, the north should adopt indoor cultivation.
The pots that have been filled with the column are taken out in the basin as a whole, and the plants that are attached to the brown skin are removed one by one, avoiding hurting the gas roots. The soil and brown column should be prepared before the basin. The soil is based on rot leaf soil. The brown column is suitable for a plastic tube with a diameter of 8 cm and a length of 1 meter. The direct basin must be carried out under 80% shade. The best cutting time is from June to August, that is, the temperature is 20°C-30°C. Cut out 3 cuttings with air roots, dip in the grass ash, insert the prepared brown column into a pot of suitable size, and close the 4 cuttings against the brown column, pay attention to the position of the bud, so as to avoid long-biased.
At this time, due to the hot weather, the soil evaporation is large and the plants must not be short of water. In order to ensure proper dry humidity, the watering method is mainly spray, except on a cloudy day, spray twice a day in order to facilitate the germination of air roots and sprouts. After January, new cuttings were issued, and thin fertilizer was applied once. Afterwards, the fertilizer was mainly foliar fertilizer, twice a month. Root application 2 times - 3 times a year. In the case of poor ventilation, high temperature and humidity, leaf spot disease is easy to obtain. The diseased leaves initially had light green water spot-size round spots on the leaves. As the lesions expanded, they developed into round or irregular brown spots, with small black spots appearing in the middle of the lesions. Control and eradicate diseased leaves and reduce the main source of infection. At the same time can be sprayed 500 times chlorothalonil or 800 times.
