The water level should also be appropriate for the water culture of pothos. For plants, most of the roots should not be covered, and at least 85% of the roots should be in the water, so as to ensure that it can absorb the water normally and will not hinder the subsequent growth. If the root has not yet grown, the water should not be more than one or two knots, which can promote the root. The height of water level is very important. If the water level is low and the root is hard to absorb water, the growth will be limited and hard to supply to the later growth, and the growth will be weakened due to water shortage. If the water level is too high, it is difficult for the roots to breathe normally, which may lead to root rot, and the whole growth will be affected.
1. Water change: in addition to ensuring the water level, pay attention to the water quality. Generally, the water is changed every 4-5 days during the growth period. In summer, the temperature is on the high side, and the water will be changed about 3 days, so the water quality cannot be turbid. Winter climate is cold, can 5 - 7 days change water, at this time do not change too often.
2. Nutrition: in addition to providing new nutrients for daily water exchange, it is also necessary to add a proper amount of nutrient solution during water exchange, so as to promote growth.
