How to grow Clivia miniata (Kaffir lily) hydroponically? Detailed methods and precautions

Although Clivia miniata is rather afraid of dampness, hydroponic cultivation of Clivia miniata can still succeed, and many friends even set up their hydroponic containers so that flowers are viewed on top, roots below, and fish admired in the water. So how should Clivia miniata be grown hydroponically at home?

Clivia miniata

I. Transferring from soil culture to hydroponics

Take a two-year-old potted Clivia miniata, rinse it clean with clear water, cut off old roots and yellow leaves, and place it in clear water that has been left to stand for 1-2 days for cultivation; the water temperature should be around 15-20°C, and initially the roots should be immersed to a depth of 1/3-1/2; gradually increase the amount until the roots are fully submerged, but if water droplets appear at the leaf tips, the water level must be lowered appropriately at once.

II. Disinfection and prevention work for the plant

During initial cultivation or each time you change the water, change the container, trim, or trim roots, you can use a clean vessel filled with a 0.1% potassium permanganate solution, and during the intervals between each operation on the plant, soak it in the solution for 3-5 minutes, then rinse with clear water and place it in the container for cultivation; this can serve to disinfect and prevent pests and diseases.

III. Soilless cultivation nutrient solution

It is composed of more than 10 macro- and micro-elements including nitrogen, phosphorus, potassium, calcium, magnesium and sulfur. There are many formulas for the elements used and their contents. For ordinary households, a small amount of potted Clivia miniata fertilizer can be used, or a dedicated hydroponic flower nutrient solution can be purchased from a flower shop.

IV. Water use and application of nutrient solution

It should be placed in a bright, well-ventilated spot. In daily care and management, generally in the hot summer season the water can be changed every other day or even every day, with a small piece of charcoal added to prevent spoilage; in winter, change it every 10-15 days, and the pH of the water used should be kept at 6.0-7.0; periodically apply a small amount of 2-3 drops of nutrient solution. Not only should the nutrient solution be added to the water, but the leaves should also be sprayed with nutrient solution (the nutrient solution can be made from Clivia miniata fertilizer or purchased at a flower shop) to make it grow vigorously.

Hydroponic methods and precautions for Clivia miniata

Clivia miniata is a common indoor potted flowering plant. From ancient times to the present, there are far too many people who like to grow Clivia miniata. Besides soil cultivation, Clivia miniata can also be grown hydroponically. Below is an introduction to hydroponic matters and operating steps for Clivia miniata, which we hope will be useful to flower lovers growing Clivia miniata.

To grow Clivia miniata hydroponically, you must first choose a good container. Generally, a transparent glass container is best. If you are growing one seedling, just a glass jar is enough. If you want to grow a large number hydroponically, you can use thin iron wire to weave a metal mesh with holes 1 cm in diameter, and make a glass hydroponic box slightly smaller than the metal mesh; or you can use a goldfish tank instead. Then cover the hydroponic box with the metal mesh, insert the Clivia miniata seedlings through the mesh holes into the nutrient solution respectively, with the depth of the flower roots in the culture solution not exceeding the pseudobulb at the base of the roots.

Nutrient solutions fall into two types: inorganic and organic. The inorganic nutrient solution can be prepared in the following proportions: calcium 1.5 g, ferrous sulfate 0.01 g, urea g, potassium dihydrogen phosphate 1 g, magnesium sulfate 0.5 g. After these 5 inorganic salts are all prepared, dissolve them in 1000 g of water and it is ready to use. The organic nutrient solution is prepared as follows: 100 g of roasted hemp seed meal, 100 g of bone meal (made from unsalted fresh bones), 150 g of soybean cake meal, 50 g of roasted sesame powder, then dissolve in 1000 g of water. Comparing the above two nutrient solutions, the organic fertilizer has rich components but low nutrient content, while the inorganic fertilizer has relatively simple components but strong fertilizer effect and quick results. To make up for each other's shortcomings, the two can be used in combination. If used alone, the inorganic fertilizer should be applied once a week, and the organic fertilizer once every 5 days.

For hydroponic Clivia miniata, you cannot directly use tap water; you must use water that has been "aged". So-called "aged" water means putting tap water in a container and exposing it to sunlight for 3-5 days, so that chlorides such as bleaching powder harmful to Clivia miniata roots settle out. In "aged" water, from the appearance, the sediment changes from strip-like to clump-like, and the water color is best when green. After the water is well "aged", the position where the roots are submerged must not submerge the pseudobulb. If the water level is too shallow, Clivia miniata cannot get a sufficient water supply; if the water level is too deep (submerging the pseudobulb), it will cause root rot. During cultivation, pay attention to observing changes in water quality. If the roots are found to be somewhat yellow or turning black, it means the water is both short of oxygen and low in nutrients, and the water must be changed immediately.

a. Choose a robust 2-3-year-old Clivia miniata, wash the roots, soak in potassium permanganate solution for 10 minutes, then rinse clean with clear water, and grow it in tap water that covers one fifth of the root system, changing the water about once every three days.

b. If rotten roots are found, trim the rotten roots and old roots. In 10-15 days, new roots can sprout from the base of the pseudobulb. Add water until it covers one half to one third of the root system. When the new roots grow to about 5 cm, switch to nutrient solution for cultivation.

c. After Clivia miniata blooms, the faded flowers need to be cut off, and a potassium dihydrogen phosphate solution should be sprayed, which can make the plant develop fully and promote flower bud differentiation.

Whether the aeration of the roots of hydroponic Clivia miniata can be handled well is the key to success or failure in hydroponics. If oxygen deficiency in the water is found, oxygen must be replenished. There are two methods: one is to change the water, and the other is to use a small oxygen pump to supply oxygen to the water. In terms of sunlight handling, Clivia miniata is a semi-shade, semi-sun plant, so attention should be paid to light. Especially in summer, avoid direct strong sunlight and let it receive scattered light. In addition, according to the light-seeking characteristic of Clivia miniata leaves, attention should be paid to making the leaves receive light evenly; otherwise the leaves will differ in length, and the growth direction will also be staggered front and back. Generally, the light angle should be adjusted once every two or three days. In terms of temperature handling, the environmental temperature for adult Clivia miniata is best at 11-25°C, and for small seedlings it can be slightly higher, 20-35°C is fine. When growing orchids in water, you must master the day-night temperature difference. In winter, keep it around 20°C during the day and not lower than 15°C at night.

Cultivation methods and precautions for hydroponic Clivia miniata How to grow Clivia miniata hydroponically

At present, most households still use soil cultivation methods for growing Clivia miniata. When they see other green plants grown hydroponically, they wonder: can my Clivia miniata be grown hydroponically? Clivia miniata has been a beloved flower from ancient times to the present. Placed in a glass container, its appearance can be fully taken in through the clear water. Today, wed114 wedding website brings you the cultivation methods and precautions for hydroponic Clivia miniata, teaching you how to grow Clivia miniata hydroponically.

The role of hydroponic Clivia miniata

Clivia miniata itself has ornamental value, and after hydroponics its appearance is greatly enhanced. As the saying goes, from the side it looks like a line, from the front like a fan. When the severe winter is a world of ice and snow, hydroponic Clivia miniata blooms warmly indoors, full of vitality.

Cultivation methods and precautions for hydroponic Clivia miniata

Container selection

A very key factor in hydroponics is the container. A suitable container is not only beautiful but also beneficial to plant growth. Generally speaking, a transparent glass container is best, making it convenient to observe the underwater situation. But if you are growing one seedling, just a glass bottle is enough (the editor also grows Clivia miniata hydroponically at home, directly buying a bottle of yogurt from the supermarket, the glass bottle kind; after drinking the yogurt, it can be used after disinfection, super convenient.) If the plant is slightly larger, you can directly use a fish tank instead.

Water requirements

Hydroponic Clivia miniata cannot directly use tap water; it must use water that has been "aged", that is, placing tap water or exposing it in the sun for 2-3 days, so that harmful chlorine such as bleaching powder in the tap water volatilizes, reducing damage to the roots. In "aged" water, from the surface, there is clump-like sediment at the bottom, and the water will appear light green.

During hydroponics, the position where the roots are submerged should not submerge the pseudobulb; pay attention to the depth of the water. If the water level is too shallow, Clivia miniata cannot get sufficient water; if the water level is too deep, it easily causes root rot. During the care process, pay attention to observing the water quality. If the roots are found to turn black or yellow, change the water immediately.

Light and air

Clivia miniata is suitable for growing in a semi-shade, semi-sun environment. During hydroponics, pay attention to light, especially in summer, avoiding direct sunlight and receiving scattered light. In order to let the leaves receive light evenly, rotate the flower pot regularly.

The growth of all things requires sufficient oxygen, so sufficient oxygen should be ensured in hydroponics. You can keep a few small fish in the container. If the small fish swim around freely, it means the water is not short of oxygen; if the small fish always float to the surface to breathe, it means the water is short of oxygen and oxygen needs to be replenished.

Specific steps for hydroponic Clivia miniata

First choose a healthy, disease-free Clivia miniata, soak it in potassium permanganate solution for 10 minutes, then rinse it clean with clear water. Try not to damage the roots, and use scissors to cut off old roots and diseased roots.

Then place it in clear water that has been left to stand for 2 days for cultivation, keeping the water temperature between 15-20°C.

At the beginning, the root immersion depth should be 1/3-1/2; gradually increase the amount until the roots are fully submerged, but if water droplets appear at the leaf tips, the water level must be lowered appropriately at once. Change the water about once every three days.

In 10-15 days, new roots can sprout from the base of the pseudobulb. Add water until it covers one half to one third of the root system. When the new roots grow to about 5 cm, it means hydroponics has succeeded. After that, you can switch to nutrient solution for cultivation.

Common problems and solutions for hydroponic Clivia miniata

Root rot

The greatest feature of hydroponic plants is that you can see the pure white root hairs, and at the same time the roots are also very prone to disease. So when hydroponic Clivia miniata develops root rot, how should it be remedied?

First take out the Clivia miniata and let the roots dry. Then soak in diluted chlorothalonil solution for several hours, after that cut off the rotten roots, and place it back into a container with fresh water and nutrient solution. After placing it in a cool, ventilated place for a week, it can basically recover.

Yellow spots

Green-leaf plants fear yellowing leaves the most. Hydroponic Clivia miniata developing yellow spots may be due to the following situations.

1. Insufficient light. Clivia miniata likes sunlight, but be careful not to expose it to strong sunlight;

2. The water level is too high, hindering root growth. The roots should be raised appropriately, and it is enough for the water level to reach three quarters of the roots.

3. Too much/too little nutrient solution. In winter, no nutrient solution may be added; in spring and autumn, the amount can be appropriately increased.
