When the stem of cycad grows to 50 cm, the old leaves are cut off when the new leaves begin to grow in spring, and then every 1 ~ 3 years. If the spreading degree of the plant is small, when the new leaves begin to grow in spring, all the old leaves can be cut off, and the new leaves grow at an open angle with a perfect crown shape. When pruning, cut to the base of petiole to keep the stem neat and beautiful.
