Portulaca iridesca like sunny, dry, cool growth environment, drought resistance, fear of water logging. The hot and humid environment is not conducive to its growth. Portulaca iridesca grows in cold season and has dormancy period in summer.
The growth period of Portulaca iridesca is from September to June of the next year. During this period, sufficient light is needed. The lack of light will lead to the growth of plants in vain, the stems of plants will become fragile, the leaves will be elongated, and the color will become light. Summer dormancy period, to strengthen ventilation, appropriate shade, to avoid the rainbow Portulaca in the sun exposure, resulting in plant sunburn.
The requirement of Portulaca iridesca on soil is not high, it can be added with peat soil and coarse sand, but the permeability of soil should be maintained. In the growth period of more than 1-2 years, according to the actual growth situation to change basin soil, remember to change basin when the first watering in early spring
When the temperature is over 35 ℃ in summer, the amaranth enters the dormancy period, and the whole independent growth basically stops, so we should reduce the watering, so as to avoid the root rot caused by too wet pot soil. In winter, when the temperature is lower than 5 ℃, water should be cut off. In the breeding process to avoid long-term rain, long-term rain will lead to root damage, branches will turn yellow rot.
The main propagation method of Portulaca iridesca is cutting. The cutting time was in spring and autumn, avoiding the dormancy period of Portulaca rainbow. Take down the healthy old branches and put them in a ventilated place to dry, and then cut them in the wet sandy soil. Put it in a cool and airy place. After 20 days, Portulaca will take root.
