Watering: spring, summer and autumn are the growth period of heavy fans, and the basin soil should be kept wet; winter is the dormancy period, and the basin soil should be kept slightly dry, and the principle of "watering is dry, through and through" should be followed. Pay attention not to water in winter, easy to lead to rotten roots.
Fertilizing: fertilize once every half a month in the growth period, select special fertilizer with more meat, and the amount of fertilizing should be less rather than more.
Heavy fan is a light loving plant, which can be maintained in full sunlight. It is suitable to be placed in a place with bright light.
The heavy fan is not cold resistant, resistant to semi shade and drought. The growth temperature is 18-25 ℃, and not less than 10 ℃ in winter.
Ramet: in spring, combine with basin changing to carry out ramet propagation, and pull out crowded stems and leaves from the inside. 3-4 plants per pot.
Cutting: wake up from May to September, cut the short and folded stem, 7-8 cm long, and put it in the sand bed, 10-15 natural roots after cutting, and potted one week later.
The heavy fan should change basin in spring. When changing basin, cut off dead leaves and long stems. Basin with diameter of 12-15cm can be used. The pot soil is a mixture of rotten leaf soil, culture soil and coarse sand, with a small amount of bone powder added.
The common pest of heavy fan is scale insect, and the common disease is leaf blight. In summer high temperature season, we should pay attention to timely ventilation, adjust indoor air humidity and temperature, and prevent the breeding of diseases and pests.
Fans like warm, humid and sunny environment, but avoid the sun exposure. Summer is the most suitable season for the growth of heavy fans, but it is also the most likely season to burn its leaves. It is necessary to pay attention to the light treatment of summer maintenance. It is not allowed to put it in the outdoor sun blindly, and it can be properly shaded.
