Hibiscus flower cultivation and maintenance skills:
Insufficient light, the flower buds are easy to fall off, the flowers are reduced, and the daily sunshine should not be less than 8 hours. Fuso has a large demand for fertilizer, and it is necessary to fill light in time. Potted hibiscus, generally out of the house in April, change the basin before leaving the house, appropriate plastic trimming, to maintain a beautiful crown, watering in the growing season should be sufficient, can not be lack of water, can not be affected, usually watered once a day, Futian can Every morning and evening. The ground is often sprinkled with water to humidify and cool down, preventing the young leaves from being dried and the flowers falling early. After the end of October, after cooling, move into the greenhouse, keep the temperature above 12 C, control the watering, and stop fertilizing. Poor ventilation in the cultivation site, insufficient light, frequent occurrence of aphids, scale insects, bituminous coal, etc., should pay attention to improve environmental conditions and choose appropriate pesticide spraying control.
Change basin and trim
Potted soil should be loose and fertile sandy loam. Before leaving the outdoor in early spring in April, the basin should be changed. There are three things to do when changing the basin: one is to replace the new culture soil; the other is to cut off some of the densely curled fibrous roots; the third is to apply the base fertilizer, and the bottom of the basin is slightly phosphated.
In order to maintain a beautiful tree shape and a large amount of flowers, according to the strong germination ability of hibiscus hair, it can be trimmed and shaped before and after leaving the house in early spring. Each branch has 2-3 buds in addition to the base, and all the upper parts are cut and cut. It can promote the development of new branches, the growth will be more vigorous, and the plant shape is also beautiful. After trimming, due to the reduction of the consumption of the aboveground part, it is necessary to properly control the water and fertilizer.
Management after leaving the house: Positive tree species in Fusang, moved to outdoor in the early morning in early sunshine, this is also the growing season of Fuso, to strengthen the management of fertilizer, loose soil, and grass. Apply a thin liquid fertilizer every 7-10 days. The watering should be based on the dry and wet conditions of the soil. If it is too dry or too wet, it will affect the flowering. Post-autumn management should be cautious, pay attention to less fertilization in the later period, so as not to send autumn shoots. The autumn shoots are young and tender, and the cold resistance is weak.
Timely entering the house Fusang is not resistant to frost, and must be moved indoors to keep warm after the frost falls. The wintering temperature requirement is not lower than 5 °C to avoid freezing damage; not higher than 15 °C, so as not to affect the dormancy. Dormancy is not good. Any furniture house with good insulation in the south can be wintered. When the weather is cold, it can be covered with paper or covered with plastic film to keep warm. Open the indoor room every day to open the window ventilation during the day, pay attention to the dry and wet changes of the basin soil, and properly water the water. In the coldest days, watering has the effect of preventing freezing damage, but fertilization should stop.
