Bamboo and cypress are strict with soil, preferring deep, fertile and loose acid sandy loam. Potted bamboo cypress generally does not need fertilization, but in order to ensure its dark green leaf color, alum fertilizer can be applied 2-3 times in the peak season of bamboo cypress growth. Bamboo and cypress will go into dormancy or semi-dormancy in winter. At this time, twigs, pests and diseases, over-dense branches and dead branches can be cut off, which not only keeps the beautiful plant shape, but also prevents the occurrence of pests and diseases.
