After leaving the room in early spring, Rohdea japonica should be placed under the canopy or eaves with shade or in the shade of the balcony to prevent rain. In addition to keeping basin soil moist in summer, watering in spring and autumn should not be too frequent, and watering should be controlled in winter. Flower leaf Rohdea japonica is the fleshy root, so it's afraid of standing water. If it's watered too much, it's easy to rot. However, it is necessary to keep the air moist, for example, the air drying is also prone to the adverse phenomena such as dry tip of leaves.
When the temperature is lower than 5 ℃ in winter, Rohdea japonica flowers and leaves are very vulnerable to cold damage, if not managed in time, it will cause death. So how to take corresponding measures against the cold disaster?
The leaves lose their luster and droop like water loss. At this time, we should move Rohdea japonica flowers and leaves to a place with high temperature, so that it will gradually return to normal. Note that the temperature should not rise suddenly after being injured, so as to avoid wilting of leaves.
In addition to drooping, the leaves of Rohdea japonica flowers and leaves will also have cold damage plaques like scalding. During the treatment, the cold spots on the leaves shall be cut off and the flowers shall be moved to a warm place.
Most of the leaves showed cold spots, and the petioles showed water stained patches and lost green. At this time, the leaves and handles should be cut off, and the wounds should be smeared with grass ash or coal ash, and then placed in a warm place, and the watering should be properly controlled to slowly return to normal.
The new leaves of twigs lose their green color, showing water stained patches, and the underground roots suffer from cold and rot.
Dig up the plants in time, cut off the underground part, cut off the damaged branches and stems, smear the wounds with plant ash, store them in the wet sand, and cut them after spring. If serious chilling injury occurs and the whole plant has spots, there is little hope to save it, so flowers should be renewed.
