How to hydroponically cultivate Echeveria 'Rainbow"
As the颜值 (appearance)担当 of the succulent world, Echeveria 'Rainbow' captivates numerous plant enthusiasts with its crystal-clear leaves. Compared to traditional soil cultivation, hydroponics allows for a more direct observation of the root growth status. But how exactly should one operate to ensure healthy plant growth? This article will provide a detailed analysis of the entire hydroponic process, from vessel selection to post-cultivation care.
The Core Four Steps of Hydroponic Cultivation of Echeveria 'Rainbow'
Container Selection and Disinfection
Preferably choose a transparent glass container or a special hydroponic bottle, with a diameter of 5-8 cm to match the plant size. Plastic bottles should be pre-washed with boiling water, while glass vessels can be soaked in a potassium permanganate solution for 20 minutes for disinfection. The container height is recommended to retain 1/3 air space to ensure adequate root breathing space.
Plant Pre-treatment Techniques
Select a robust soil-grown plant, shake off the soil from the roots, and trim the dead roots. Soak in a carbendazim solution for 15 minutes to kill bacteria, then place it in a shaded area to dry for 2 days to promote wound healing. Retaining a main root of 3-5 cm is more beneficial for hydroponic rooting.
Water Level Control and Placement Orientation
Fill with tap water that has been exposed to air for 2 days, with the water level 0.5 cm away from the base of the roots. Change the water once a week initially, and after new roots appear, change it every half month. Place it on an east-facing windowsill, ensuring 3-4 hours of scattered light daily.
Key Points for Post-Hydroponic Cultivation Care
Nutrition Supplement Strategy
Add a special hydroponic nutrient solution when changing water, with the concentration controlled at 1/3 of the standard specified in the instructions. Stop fertilizing during the winter dormancy period, and supplement with a trace element solution once a month during the spring and autumn growing seasons.
Environmental Control Guide
Maintain an ideal temperature of 15-25°C, and move to an air-conditioned room if the temperature exceeds 32°C in summer. Keep the air humidity between 40%-60%, which can be adjusted by placing wet陶粒 (clay pebbles) in a tray. Regularly rotate the bottle to avoid phototropic growth.
Although hydroponically cultivated Echeveria 'Rainbow' may not be as vigorous as soil-grown ones, it presents a unique ornamental value. Mastering water level control, nutrition management, and environmental maintenance are the three core aspects. Even beginners can cultivate a crystal-clear hydroponic landscape. It is recommended to switch to soil cultivation for one month every half year, using the soil-hydro alternating method to extend the plant's lifespan.
