Li Ke reminds us that after picking out a healthy bulb, remember to cut openings in the top of the bulb before you put it in water. Cut two 2cm openings, on either side of the top of the bulb, to help the shoots grow evenly. Be careful not to make the cuts too deep--no deeper than three or four layers--otherwise, they will wound the buds.
李珂提醒，選好健康的球莖之後，下水前要記得先作開口處理，在花頭腹背兩面（側芽方向）各開長約兩公分的口，以利次芽平均生長，但要注意不可過深（約三四層鱗片），以免傷及花芽。
