Can the Radermachera sinica be grown in water? Detailed explanation of hydroponic methods and cultivation management key points
Radermachera sinica is a common ornamental plant. Everyone must be especially curious about whether Radermachera sinica can be grown hydroponically. In fact, theoretically all plants can be grown hydroponically, because the nutrients plants need are all dissolved in water. As long as the nutrient solution for Radermachera sinica is properly prepared, let us take a look below at the hydroponic method for Radermachera sinica!
Hydroponic method for Radermachera sinica
1. Hydroponic cultivation: To grow Radermachera sinica hydroponically, you must first choose a healthy plant free of disease. Then remove the soil from the roots, wash them clean with clear water, washing several times, trying not to damage the roots. Before this, you can use carbendazim and other chemicals to sterilize once, which makes root rot less likely. Pass its roots through the plastic seedling-holding grid attached to the hydroponic glass container. If it is too small, the grid can be cut larger. Fill the container with clear water to two-thirds of its volume, and immerse two-thirds of the roots in the water.
2. Change the water in time: For hydroponic cultivation of Radermachera sinica, you must change the water once a week until enough new roots grow. Wash the container clean, replace with a specially prepared nutrient solution, also filling two-thirds of the volume. Other operations are the same as above, and the nutrient solution should be renewed regularly.
Reasons for Radermachera sinica dropping leaves
1. Water reason: The most common reason in daily life is the amount of watering. We know that Radermachera sinica is a plant that relatively likes water, but too much or too little can cause it to drop leaves. If you are rather lazy and always wait a week before remembering to water, at that time the soil is too dry and the roots are fragile. If you suddenly water too much, the roots will be damaged, hindering leaf growth and causing leaves to drop. But usually do not water too much either, to avoid root rot.
2. Light reason: All plants need light to ensure growth. If you place Radermachera sinica in a dark place for a long time, it will make it unhappy. Especially in winter, you should often take it out to get some sun. Of course, in the hot summer, it cannot always be in the sun, to prevent the leaves from being scorched.
3. Temperature reason: Radermachera sinica likes a warm and mildly hot environment. The suitable growth temperature is 20°C to 30°C. In the hot summer, everyone needs to pay attention to moisture retention, provide appropriate shade, and increase water spraying on the environment and leaf surfaces. In the north, everyone should pay attention to temperature and place Radermachera sinica in a room with a suitable temperature.
4. Fertilizer reason: For potted Radermachera sinica, besides requiring an appropriate amount of decomposed cake fertilizer and 3% multi-element compound fertilizer in the culture soil, topdressing should also be given continuously. During the growing season, a quick-acting liquid fertilizer can be applied once a month, usually decomposed cake fertilizer water. For a small number of home potted plants, or for large potted plants displayed in public places for a long time, a small amount of multi-element slow-release compound fertilizer granules can be buried and applied regularly, or a mixed solution of 0.2% urea plus 0.1% potassium dihydrogen phosphate can be used for watering.
Cultivation methods for Radermachera sinica
1. Temperature: Radermachera sinica likes a warm and humid environment, and temperature is the most important. Keeping the daytime temperature between 19°C-21°C and the nighttime temperature between 18°C-20°C is the most suitable growth temperature. Too high or too low will affect its growth. In the hot midsummer, try to keep the temperature below 27°C. When the ambient temperature is very high, appropriately use a shed for shading. Increase environmental humidity, thereby increasing leaf surface humidity. In winter, the temperature cannot be lower than 8°C, and the humidity cannot be less than 5°C, otherwise below this temperature it will be frostbitten.
2. Humidity: Radermachera sinica relatively likes moisture in both soil environment and indoor environment requirements. Indoor humidity should be controlled between 70-80%. In large banquet halls where humidity cannot be controlled, we spray the leaf surfaces once in the morning and once in the evening. If the humidity is too low or it is in a dry environment for a long time, the leaves will curl and turn yellow, affecting ornamental value.
3. Light: Radermachera sinica is a plant that likes sunlight and is also shade-tolerant. Light is very important. Radermachera sinica likes to grow in a semi-shaded environment. In the north, under normal circumstances we all grow it indoors, so there is no problem of direct sunlight. Instead, it is afraid of being placed in a dark place for a long time, where neither direct light nor scattered light can reach. After a long time, it will certainly drop leaves. Therefore, in winter it should be placed on a balcony or in front of a window with sufficient sunlight to supplement light.
4. Watering: In summer, potted Radermachera sinica should be watered once every 3 to 4 days, but this also depends on the individual situation. In winter, indoors in the north, Radermachera sinica almost stops growing, and watering should be controlled so that the potting soil is just not dry. When watering, water thoroughly. If not watering, then not a single drop of water should be poured into the pot. This is the principle, please everyone remember it.
5. Pruning: The purpose of growing Radermachera sinica is for ornament and to complement the indoor environment. If the tree shape does not look decent, then it is not beautiful, so it should be pruned carefully, generally pruned into a mushroom shape or a rounded mound shape. Cut off some old leaves and yellow leaves.
6. Soil: When Radermachera sinica is growing, soil is equally important. Choose a loose, breathable, well-draining and nutritious soil texture. Usually use garden soil : leaf mold : decomposed organic fertilizer : river sand = 5:3:1:1 ratio to prepare it. Persist in loosening the soil once a month during the growing season to ensure that the root area is always in a well-aerated state. If water accumulation in the pot is found, drain it as soon as possible, and after the potting soil dries, repot and change the soil to keep Radermachera sinica growing better.
7. Fertilizing: During the growing period, fertilize Radermachera sinica diligently to ensure vigorous growth. Compound fertilizer or nitrogen-phosphorus-potassium 20:10:10 or farmyard manure, etc. In winter, fertilizing can be stopped.
8. Pest and disease prevention: Pests on Radermachera sinica generally include scale insects, mites, and aphids. Use Jie Bi Si, methidathion, Man Jing, fenbutatin oxide, phoxim, omethoate, and deltamethrin for pest control. As long as ventilation and air exchange are frequent, generally pests will not occur. Radermachera sinica's disease resistance is still quite strong. If the pest problem is not severe, you may remove them by hand.
The effects and cultivation methods of lucky bamboo
Lucky bamboo represents wood, that is, plants, and can also replace the pen. Placing lucky bamboo (water-grown) at the wealth position in the home can activate the wealth position and achieve the effect of promoting wealth.Lucky bamboo is suitable for growing under bright scattered light. Too strong light or exposure to the sun will cause leaves to turn yellow, fade green, and grow slowly. Change the clear water once every 3-4 days. A few small pieces of charcoal can be added to prevent rot. Do not move the position or change the direction within 10 days. After about 15 days, silver-white fibrous roots can grow. After rooting, it is not suitable to change the water; after the water evaporates, only add water in time. Frequent water changes easily cause yellow leaves and withered branches. (In feng shui, lucky bamboo is not recommended, so there is no particular emphasis on what position it can be placed in.)The effects of lucky bamboo
Lucky bamboo is a shade-tolerant, moisture-tolerant, foliage-type plant. Scientific testing has long confirmed that plants, especially green leafy ornamental plants, indeed have a good effect on purifying indoor environmental pollutants.
Lucky bamboo has slender stems and leaves, is soft and elegant, with a natural and unrestrained posture, full of bamboo charm, and is a plant with particularly high ornamental value.
What does lucky bamboo symbolize
The scientific name of lucky bamboo is Dracaena sanderiana, originally named Xian Da Long Tie Shu, also called lucky bamboo and green-leaf bamboo banana. It belongs to the Agavaceae family, Dracaena genus, and is an evergreen upright shrub.
Because lucky bamboo roots easily and survives easily, water cultivation is currently popular on the market.
Lucky bamboo mainly includes four types: green-leaf lucky bamboo, golden-edged lucky bamboo, silver-edged lucky bamboo, and the lotus bamboo that has risen in recent years. Because people have a particular preference for green-leaf lucky bamboo, what we usually call lucky bamboo specifically refers to green-leaf lucky bamboo.
Although lucky bamboo is not a bamboo, because it is evergreen all year round, with slender stems and leaves, soft and elegant, with a natural and unrestrained posture, particularly high ornamental value, and is upright and noble, extremely full of bamboo charm, the clever Chinese people gave it this auspicious beautiful name, seeking "flowers bloom in wealth and honor, bamboo reports peace." Today, lucky bamboo has come to symbolize "wealth and good fortune," "rising step by step," "everlasting youth," "evergreen life," and "great good luck and great profit."How to grow lucky bamboo
For growing lucky bamboo in a vase with water, the following key points should be mastered:
1. Before placing it in, cut off the leaves at the base of the cuttings, and cut the base into a slanted opening with a sharp knife. The cut should be smooth to facilitate the absorption of water and nutrients. Change the clear water once every 3-4 days. Do not move the position or change the direction within 10 days. After about 15 days, silver-white fibrous roots can grow.
2. After rooting, it is not suitable to change the water; only add water in time after the water evaporates and decreases. Frequent water changes easily cause yellow leaves and withered branches.
3. After rooting, apply a small amount of compound chemical fertilizer in time, and then the leaves will be glossy green and the branches stout. If no fertilizer is applied for a long time, the plant will grow thin and weak, and the leaf color will easily turn yellow. But fertilizing cannot be excessive, to avoid "burning roots" or causing leggy growth. In spring and autumn, applying compound chemical fertilizer once a month is enough. According to references, for water-grown lucky bamboo, to prevent leggy growth, do not apply chemical fertilizer. It is best to inject a few drops of brandy into the bottle about every 3 weeks, add a small amount of nutrient solution, and then the leaves can remain emerald green.
4. Do not place lucky bamboo beside a television or in places often blown by air conditioners or electric fans, to avoid the leaf tips and leaf edges drying up.
If your hydroponic lucky bamboo (fortune bamboo) shows yellowing leaves, you can look for the cause from the following two aspects: First, check the water quality, mainly to see whether the root system is fresh. If root rot is caused by water quality, then switch to cooled boiled water. Second, check the lighting conditions of the placement location. If the light is too dim, stuffy and unventilated, or the air is dry, all can cause leaves to turn yellow; but if the placement location has too strong light, it will likewise cause leaves to turn yellow and lose their spirit.
What should be done about lucky bamboo with yellowing leaves? If it is caused by light, first cut off the yellow leaves, and also cut off rotten roots. Then create a clean, suitably warm, cool, moist environment with relatively good scattered light for it. If root rot is caused by unclean water quality, first cut off the yellow leaves. When the symptoms are not serious, it is advisable to change the water frequently and place it in a ventilated position with relatively sufficient sunlight for restorative care; when the symptoms are serious, appropriately spray pesticide or add a small amount of fungicide to the water dish.
Other questions"
Your lucky bamboo leaves may be yellow because the temperature is low.
It is an evergreen woody plant. It likes high temperature and high humidity environments, and is also shade-tolerant and waterlogging-tolerant, with a certain cold resistance. When the winter temperature is below 10°C, the leaves will turn yellow and fall off.
When used as an indoor ornamental, generally no nutrients are added to the soaking liquid of lucky bamboo, to prevent stem node rot. It is best to use overnight tap water or cooled boiled water for growing it. It can be replaced once every 10 to 15 days, and once every 5 to 7 days in summer. But each time only pour out half and add a new half; it is not suitable to replace all of it, otherwise the root system will not be able to adapt. If you want the water-grown lucky bamboo to continue growing, then add a small amount of urea and potassium dihydrogen phosphate aqueous solution to the soaking liquid. The concentration can be controlled at about 0.1%, replacing it once every half month. The fertilizer liquid can also be sprayed on the leaf surfaces. When it grows many new shoots, cut off diseased shoots and pest-infected shoots early, otherwise it will bring harm to the whole pot of lucky bamboo; for weak shoots, "bully shoots," etc., under the premise of not affecting the overall shape and ornamental value of the lucky bamboo, appropriate thinning pruning is also very necessary. It adds a quiet, warm, and happy atmosphere.
It is not only low temperature; low air humidity and relatively dry conditions will also cause this situation.
Lucky bamboo is native to the Canary Islands and the tropical regions of Africa and Asia, and is now widely introduced and cultivated in China. It likes high-temperature and high-humidity environments, and has no strict requirements for light. It likes light and can also tolerate shade. It is suitable for growing in well-drained sandy loam. The suitable growth temperature is 20-30°C, and the overwintering temperature is 10°C.
Lucky bamboo is propagated by cuttings. Cuttings are mostly carried out in combination with shaping and pruning. As lucky bamboo grows taller over many years, the leaves at the base of the stem often fall off and the plant shape deteriorates; during the growing season, the stem can be cut into 5-10 cm lengths as cuttings, and inserted into vermiculite or river sand. Generally, roots and sprouts will form in 1-2 weeks.
For potted lucky bamboo, equal parts of leaf mold, garden soil, and river sand can be mixed for planting, or coconut coir and leaf mold plus a small amount of base fertilizer can be used as the culture soil. In management, the key is to master humidity and temperature well. During the growing season, the potting soil should often be kept moist, and water should often be sprayed on the leaf surfaces to maintain relatively high environmental humidity. Too dry will cause leaf tips to dry up; in winter, the potting soil should not be too wet, but water should still often be sprayed on the leaf surfaces. At the same time, pay attention to cold protection to avoid leaves turning yellow, shrinking, and even falling off. In the vigorous growing months from May to September, apply liquid fertilizer or granular compound fertilizer 2-3 times a month to keep the leaves green and glossy. It has no strict requirements for light and is suitable for growing under bright scattered light. Avoid direct scorching sunlight; if exposed to the sun or dry conditions, the leaf surface will become rough, scorched, and lack luster, reducing ornamental value.
Netizen question:
I just bought lucky bamboo and cut the roots at a slant, but after only a few days of growing it, the leaves turned yellow?
Answer:
For the several stems you cut with scissors, cut them off with a sharp knife 1 cm below a node slightly higher up. Cutting near the node makes rooting easier. Put them back into water.How to water lucky bamboo?
Watering lucky bamboo is relatively easy. You can go several days without watering. When the soil is very dry, water it thoroughly once, and after a few days when the soil is relatively dry, water again.
Besides paying attention to watering, you also need to pay attention to some other matters, otherwise lucky bamboo easily gets yellow leaves.
Potted lucky bamboo
Pot soil selection For cultivating lucky bamboo, purple clay pots and plastic pots are suitable, while outdoors earthenware pots are best. It is not very choosy about soil, and grows most robustly in loose, fertile sandy loam. Leaf mold, vegetable garden soil, and sand can be mixed in a 5:4:1 ratio as culture soil. If a small amount of crushed eggshell is mixed in, it will grow even more vigorously. Repot and change the soil once every spring. When repotting and changing soil, it is advisable to place a layer of crushed hard plastic foam blocks at the bottom of the pot to facilitate ventilation and drainage, prevent root rot, and make it easier to remove the plant from the pot.
What should be noted when hydroponically growing lucky bamboo
Introduction to lucky bamboo
Lucky bamboo, originally called Dracaena sanderiana, with aliases bamboo banana and ten-thousand-year bamboo. In Taiwan, China, South Korea, and Japan, it is called wan nian qing. It belongs to the Asparagaceae family, Dracaena genus. It is native to Cameroon in western Africa and was introduced in large quantities to China in the late 1970s for ornamental use. It is now a common ornamental plant in China. It can be used for soil cultivation and water cultivation. Water-grown lucky bamboo can also live for more than several years.

Value: China has the congratulatory phrase "flowers bloom in wealth and honor, bamboo reports peace." Because lucky bamboo has slender stems and leaves, is soft and elegant, and is extremely full of bamboo charm, it is very much loved by people. Lucky bamboo is easy to manage, has few pests and diseases, is easy to cultivate, and symbolizes "great good luck and great profit."
Lucky bamboo stands elegantly like jade, with a handsome appearance, evergreen in winter and summer, green leaves with yellow edges, and a noble color. It gives people a sense of nobility and good fortune. That is the so-called "fortune bamboo," with green branches and emerald leaves, appearing even more full of life, and therefore deeply welcomed!
What to do if hydroponic lucky bamboo leaves turn yellow
The lucky bamboo at home often has yellow leaves, but you do not know where the cause is! Grow it according to the following methods, and the leaves will not turn yellow.
During the growth process of lucky bamboo, yellowing leaves often occur, and the cause is mostly due to improper cultivation management. Too much or too little water, too strong or too weak sunlight, and too much or too little fertilizer can all cause leaves to turn yellow, but the yellowing conditions are different. The causes should be carefully observed and analyzed, and corrected.
Water yellow: Tender leaves are dull yellow and lusterless, old leaves show no obvious change, branches are thin and yellow-green, and new shoots shrink and stop growing, indicating excessive watering. Remove the plant from the pot, place it in a ventilated, cool place to let the soil ball dry by itself, then put it back into the pot.
Drought yellow: The yellow from lack of water is different from the yellow from too much water. The yellow from lack of water is that the leaf tips or edges become scorched and dry, and old leaves turn yellow and fall off from bottom to top, but new leaf growth is relatively normal. Just pay attention to watering enough and thoroughly.
Scorch yellow: Strong direct sunlight shining on some shade-loving flowers (such as spider plant, hosta, etc.) easily causes the leaf tips and leaf edges to scorch and dry, and yellow spots appear on the sun-facing parts of the leaves. Move it to a shaded place.

It adds a quiet, warm, and happy atmosphere.
Root rot in hydroponic lucky bamboo
After water-grown lucky bamboo has rooted, it is not suitable to change the water; only add water in time after the water evaporates. Frequent water changes easily cause yellow leaves and withered branches. The added water is best well water. If using tap water, it must first be stored in a container for one day. The water should be kept clean and fresh. Do not use dirty water, hard water, or water mixed with oil, otherwise root rot easily occurs. If root rot has already appeared, it is best to cut it off first, then put a small amount of charcoal into the water to purify the water quality and prevent rot.
