Cinnabar root likes a warm growing environment, and its suitable temperature is between 16 ℃ and 28 ℃. It is not very cold-resistant, so the winter temperature can not be lower than 5 ℃. Moreover, cinnabar root is also not heat-resistant, and it grows slowly when the temperature is higher than 32 ℃ in summer. Therefore, when cultivating cinnabar root, heat preservation measures should be taken in winter, shade should be paid attention to in summer, water should be sprayed to plants, and ventilation should be strengthened to reduce the temperature of growing environment.
Cinnabar root likes a semi overcast environment. It needs bright scattered light to avoid direct sunlight. In general, the cinnabar root needs to be exposed to sufficient light, but when the sun is too strong, attention should be paid to shade, and in winter, attention should be paid to make the cinnabar root more exposed to the sun to avoid fruit falling.
Cinnabar root is suitable for growing in humid or semi-dry environment. It should not be dry or ponding. The air phase humidity of the growing environment is required to be between 50% and 70%. During the growing period of cinnabar root, the water should be sufficient and the basin soil should be wet, but not too much water, otherwise the ponding in the basin will make the cinnabar root rot. In winter, water should be controlled and the basin soil should not be too wet.
In order to make cinnabar root grow well and produce beautiful fruit, fertilizer is indispensable. During the growth period, more nitrogen fertilizer can be applied to promote the growth of branches and leaves. Before flowering, some phosphorus fertilizer and potassium fertilizer can be applied to promote flowering and fruit. Pay attention to stop fertilizing after winter.
Cinnabar root has high ornamental value and needs to be pruned frequently to form a plump plant type.
With the growth of the plant, the old pot will inevitably affect the further development of cinnabar root. It can be changed in spring every year and replaced with new culture soil.
The common diseases and insect pests of cinnabar root include stem rot, root rot, blight, leaf spot, root knot nematode, scale insect, aphid and night moth.
