– Watering: During the period when the plants are young, they need to be watered all year round to provide enough water for the young buds to form and develop. Especially in the first time after planting, watering needs to be maintained every 3-4 days.

After picking, it should be transported immediately to the place of consumption because when it is ripe, even if it is na dai, it is still easy to break.
