1、 Why close

Water lilies open during the day and close at night. This is a habit of plants. They will slowly wake up at eight or nine o'clock every morning and gradually raise their heads. At noon, they will open bright flowers. In the evening, with the arrival of night, water lilies will close their petals. The main reason for this is that it is sensitive to the sun. In the morning, the sun rises, and then the water lily will slowly wake up. The outside of the petals contacts the sun, and then stretch out and bloom. In the evening, when the inner side is exposed to the sun, it will gradually close to the inside, so it will slowly close up

2、 How to raise it in a vase

1. Treat the water lily first, and cut the part of the stem obliquely with scissors, which can increase the area of water absorption and the possibility of rooting

2. Wash the prepared vase, then disinfect it, then fill it with clean water and add nutrient solution

3. Insert the flowers into the water bottle, put them on the balcony to touch the sun, and then change the water inside regularly
