How to Grow Aglaonema modestum in Water? Detailed Methods and Steps
1. Root-washing method
①Select a robust, well-grown Aglaonema modestum (Chinese evergreen) with ornamental value that has been cultivated in soil (or other substrate).
②Remove the plant from the pot and clear away the soil around the roots.
③Rinse the soil off in water, trim away some old roots; to prevent root rot in the early stage of water culture and promote new root growth, soak in 0.5% potassium permanganate for disinfection.
④Place the prepared Aglaonema modestum plant into a ready container, add tap water until it covers 2/3 to 1/2 of the root system, and cultivate new roots.
2. Water-cutting method
Generally carried out in spring and autumn, because late autumn and early spring do not reach the temperature required for rooting, and in the high-temperature summer season the cuttings are susceptible to microbial infection and rot. Of course, under conditions with heating and cooling, Aglaonema modestum can be water-propagated in all four seasons.
When water-cutting, select a sturdy branch about 1cm in diameter, keep the aerial roots on the stem nodes, cut into 10cm-long sections, disinfect the cut with potassium permanganate (you may dip in rooting powder or soak the base of the cutting in 100mg/L auxin for 0.5h), let the sap flowing from the wound dry, then insert into plain sand or water, maintain high air humidity at around 25°C; after 20 days the base of the cutting will root and sprout to form a plant material suitable for water culture.
During the healing and rooting period of water cuttings, respiration is relatively vigorous and a sufficient oxygen supply is essential. Therefore, at the beginning of water-cutting, change the water frequently to keep the water clean and meet the cuttings' oxygen needs. When changing the water, rinse the cuttings and the vessel with clean water, especially strengthen the rinsing of the cut surface. Once rooted, they can be transferred to normal water-culture maintenance.
3. Division method
Division is usually carried out in spring when growth begins; spring division reduces damage to the plant and allows the divided plants to recover normal growth relatively quickly. When dividing Aglaonema modestum, first remove the plant from the pot, shake off most of the potting soil, untangle the tangled root system to expose the tiller shoots and roots, then as needed use a sharp knife to divide the mother plant at the stem base into several clumps, disinfect the wounds (apply plant ash or sulfur), rinse, and then carry out water-culture maintenance.
The above is an introduction to the water-culture methods for Aglaonema modestum. Below we will introduce the uses of Aglaonema modestum.
What Are the Water-Culture Maintenance Methods for Aglaonema modestum?
A few days ago a friend asked me what the water-culture maintenance methods for Aglaonema modestum are. He said his Aglaonema modestum had developed all sorts of problems, and he was very worried, not knowing how to grow Aglaonema modestum in water. Below, the editor will introduce what the water-culture maintenance methods for Aglaonema modestum are.
What Are the Water-Culture Maintenance Methods for Aglaonema modestum?
1. Changing water: Aglaonema modestum growing in water continuously consumes the oxygen in the water. As the plant grows, the oxygen in the water gradually decreases; when it drops to a certain level, it will adversely affect the plant. Therefore, whether water-culture plants succeed or not, the most critical measure is changing the water. Since the oxygen content in water is inversely proportional to the air temperature (that is, the higher the air and water temperature, the lower the oxygen content in the water; the lower the air and water temperature, the higher the oxygen content in the water), and Aglaonema modestum has different oxygen needs at different times, the interval between water changes varies with the season;
In spring and autumn, Aglaonema modestum grows relatively vigorously and needs to consume more oxygen, but the oxygen content in the water is also relatively high, so change the water once every 7-10 days; in winter, the plant's growth is dormant or very slow, consuming little oxygen, while the water contains sufficient oxygen, so the water-change interval is longer, generally changing water once about every 15 days; in summer when temperatures are high, Aglaonema modestum respires strongly and needs to consume a large amount of oxygen, while at the same time the oxygen content in the water is very low; in addition, at high temperatures microorganisms multiply very rapidly, easily causing the water quality to deteriorate. To ensure the normal growth of Aglaonema modestum, water changes must be strengthened, generally changing water once every 4-5 days.
The water used for water-culturing Aglaonema modestum should be pollution-free and slightly acidic. If tap water is used, it must be drawn in advance and left in the air for more than a day to fully dissolve oxygen and release chlorine. When changing the water, wash away the mucus on the roots and cut off rotten roots and scorched leaves.
2. Fertilizing: The nutrients in tap water are insufficient for the healthy growth of water-cultured Aglaonema modestum. For water-cultured Aglaonema modestum, use a special foliage-plant formula nutrient solution and apply it according to the instructions. In the vigorous spring and autumn growing seasons, add the nutrient solution more frequently; in summer high temperatures and winter low temperatures when growth is slow or paused, reduce the frequency of application.
When growing in a solid substrate, do not add too much nutrient solution; it is best to cover 1/3-1/2 of the root system in the container, and top up with water on ordinary days to maintain the water level. Never apply chemical fertilizers such as urea directly into the water-culture container. Because urea is a synthetic organic fertilizer, water-cultured plants not only cannot directly absorb the needed nutrients from urea, but some harmful bacteria or other microorganisms can obtain an effective carbon source from urea and multiply rapidly, causing contamination. Moreover, urea can also lead to ammonia gas poisoning or excess ammonium ion damage, poisoning the water-cultured Aglaonema modestum.
3. Ventilation: The oxygen content in water is an important factor in the growth quality of water-cultured Aglaonema modestum, and the oxygen content in water is also related to the activities of people indoors and the ventilation conditions. When a room is poorly ventilated and people are frequently active, the oxygen content in the water decreases quickly, thereby affecting the growth of Aglaonema modestum, especially obvious during high-temperature periods. Therefore, for rooms where water-cultured Aglaonema modestum is placed, doors and windows should be opened more often for ventilation in ordinary times, to regulate the room temperature and keep the indoor air fresh.
4. Pest and disease control: Water-cultured Aglaonema modestum rarely suffers from pests and diseases. In summer, avoid direct strong light to prevent sunburn; in winter, avoid insufficient light to prevent yellow leaves. Water-cultured Aglaonema modestum rarely develops anthracnose, which causes soft rot and dry cracking. When it occurs, it can be controlled with a 600-800 times dilution of 65% zineb or an 800 times dilution of 75% chlorothalonil.
That is all for the introduction of what the water-culture maintenance methods for Aglaonema modestum are. If you want water-cultured Aglaonema modestum to grow vigorously, you also need to understand its growth habits. I hope this article provides some help to friends who grow Aglaonema modestum in water.
