Hydroponic cactus changes the traditional soil cultivation method to hydroponics. Water is held in a transparent container and the roots are partially immersed in the water to absorb nutrients. This method is clean and highly ornamental, but it is necessary to pay attention to regular water changes, keeping the water quality clean, and providing appropriate light to ensure the healthy growth of the cactus.
The first step in hydroponic cactus cultivation is to select a healthy cactus. The ideal plant should have a robust ball and a downward-protruding rhizome. The varieties grafted with Mitsubishi sword are especially recommended, and these plants tend to have more adaptability and growth potential.
Treating the roots
After removing the cactus from the soil, it is necessary to cut off the original dead roots at the bottom and thoroughly wash the roots with clean water to ensure that all soil components are removed. This step is to reduce the influence of the original soil roots on the new environment and promote the generation of new roots.
Preparing the nutrient solution
The "water" used for hydroponic cactus is actually a specially prepared nutrient solution. Choosing an ammonia-free prescription nutrient solution is helpful for the growth and health of the plant. Place the treated cactus into the container, and note that the water level should not exceed 1/3 of the bottle to prevent the ball from rotting due to long-term immersion in water.
Magnetizing the nutrient solution
In order to accelerate the rooting process, you can buy two magnets with a diameter of 6-10 cm and put them into the container to magnetize the nutrient solution. The magnetized nutrient solution can improve the efficiency of plant nutrient absorption.
Providing a suitable environment
Place the planted cactus in a strong scattered light environment and keep the temperature above 20 degrees. Avoid direct sunlight to prevent the plant from being burned. At the same time, maintain good ventilation in the environment to reduce the risk of pathogen growth.
Daily care
Temperature control: Ensure that the temperature of the hydroponic environment is maintained between 5 and 30 °C. This temperature range is very suitable for the growth of cactus.
Light management: Hydroponic cactus needs sufficient light, but it does not necessarily need to be exposed to the sun. In summer, direct sunlight should be avoided as much as possible to prevent the plant from being burned.
Regular replacement of nutrient solution: During the hydroponic process of cactus, the nutrient solution needs to be replaced regularly. Generally speaking, it should be replaced every 7 days in summer and every 10-15 days in winter. Add a few drops of special nutrient solution for hydroponics each time when replacing the nutrient solution.
Root cleaning: Regularly wash the mucus on the roots of the cactus with water and promptly trim off the old and rotten roots to maintain the health of the root system.
Spraying foliar fertilizer: Spray foliar fertilizer once a week, which can not only provide nutrients but also increase the glossiness of the leaves. In winter, spraying foliar fertilizer helps to improve the cold resistance of the cactus.
Can hydroponic cactus bloom? Yes, hydroponic cactus can also bloom. However, to make hydroponic cactus bloom, the following points need to be noted:
Choose varieties that bloom frequently: Choose cactus varieties that bloom frequently, such as Gymnocalycium baldianum and Astrophytum myriostigma. These cactus varieties can bloom many times a year and are relatively easy to bloom.
Choose a large enough ball: The cactus needs to grow large enough and reach the blooming age before it can bloom during the hydroponic process. Therefore, it is easier to see the blooming results if you choose a cactus that has already grown large enough for hydroponic cultivation.
Provide sufficient light: Cactus has very strict requirements for light. If there is a lack of light, its growth point will grow spindly and may lead to no blooming. Therefore, during the hydroponic process, the cactus must be placed in a place with sufficient light.
Hydroponic cactus needs regular water changes and addition of nutrient solution to ensure the nutrients needed for its growth. Under the premise of sufficient light, the water will often become dirty, so it needs to be changed frequently. At the same time, regular addition of nutrient solution can promote the growth and blooming of cactus.
Hydroponic cactus can not only be successfully cultivated but also bloom. As long as you pay attention to the key links such as material selection, root treatment, providing a suitable environment and daily care, you can make the hydroponic cactus grow healthily and bloom beautiful flowers.
