How to grow pothos in water? Growing methods and care management tips
Pothos grown in water is a climbing foliage plant. Its vines are slender and soft, and its leaves are delicate and elegant. It is a favorite plant on office desks, and many companies like to place pothos around, so how do you grow pothos in water well, and how do you care for and manage pothos in water?
Growing methods for pothos in water
Pothos in water is mainly grown by cuttings. In late spring and early summer, cut 15 cm to 30 cm stems, remove the leaves from 1 to 2 nodes at the base, and plant directly in pots with growing soil, 3 to 5 stems per pot, water thoroughly, and place in a cool, ventilated spot. Keep the potting soil moist, and in about one month it will take root and sprout, and in the same year it can grow into a plant with ornamental value. In spring and summer, stem cuttings root easily; for a totem pole, you must use tip cuttings with large leaves, so that it takes shape relatively quickly. Pothos in water can also be grown in water, but compared with soil growing, the plant is smaller. Newly cut pothos for water growing generally needs within one week to grow roots.
Care and management of pothos in water
In the north in autumn and winter, to make up for the lack of temperature and photosynthesis, its light exposure should be increased. The method is to place the pothos in water in the spot with the best indoor light, or move it to a sealed balcony to bask in the sun at noon. At the same time, when the temperature is low, open the windows as little as possible, because in a very short time the leaves may be damaged by freezing. At a room temperature above 10°C, pothos in water can safely overwinter, and at a room temperature above 20°C, pothos in water can grow normally. For an ordinary household, reaching this temperature is not a big problem. What needs attention is avoiding too large a temperature difference, and also making sure the leaves do not get close to heating equipment.
The amount of watering in autumn and winter should be strictly controlled according to room temperature. Before heating, when the temperature is lower, the plant's soil evaporates more slowly, so watering should be reduced, and the amount of water should be controlled at 1/4-1/2 of the original. Even after heating, watering should not be too frequent. When watering, pour less into the pot, and water should seep through the coir. In addition, water should also be sprayed at the places where aerial roots grow on the coir pole, to reduce insufficient root water uptake caused by too-rapid evaporation. For winter watering, water that has been left to sit for a day is better; water that is too cold easily damages the roots.
In autumn and winter, plants mostly grow slowly or even stop growing, so fertilizing should be reduced. Before winter begins, mainly use liquid inorganic fertilizer, about once every 15 days. After winter begins, fertilization should mainly be foliar spraying, applied mainly through the stomata on the leaf surface; fertilizer is absorbed through the stomata on the leaf surface, and the fertilizer effect can act directly on the leaf surface. Special fertilizer should be used for foliar fertilizer; ordinary inorganic fertilizer is not easily absorbed by the leaf surface.
Pothos in water grows relatively quickly and is easy to cultivate and manage. During cultivation and management, in summer, water should be sprayed on the plant more often, and nutrient solution should be added once every 10 days, to keep the leaves green. For potted seedlings, when the seedling grows 30 cm up the growing pole, it should be cut off; when the lower leaves have fallen off by 30%-50%, it should be discarded and replanted. Green-column potted plants are ideal plants for courtyard gateposts and wall greening, and their leaves are also an excellent choice for flower arrangement foliage. Plant 4-5 plants per pot or insert cuttings directly, and set up a coir pole in the middle of the pot, to make it easy for the pothos in water to twine and grow upward. Shaping and pruning should be done in spring.
When the stems have climbed all over the coir pole and the tips exceed the coir pole by about 20 cm, cut off 40 cm of the stem tips of 2-3 of the plants. After new buds and new leaves sprout following the cutting back, then cut off the stem tips of the remaining plants.
