Cut once a year. Taro stems should be properly cut off in August and cut once a year, which is beneficial to the growth of taro and is very beneficial to increasing taro yield. It should be noted that cutting off the stems does not mean cutting off all the above-ground stems. In that case, the taro will stop growing and developing. At a suitable temperature, the taro will sprout again, which will seriously affect the quality and yield of the taro. The correct way is to cut off the lateral stems of each taro plant, leaving only two or three main stems. This will not only avoid excessive absorption of nutrients by the stems, but also promote the rapid growth and development of the bulbs.
