Can Euphorbia stricta be hydroponically cultivated?
As a distinctive member of the succulent plant family, Euphorbia stricta is deeply loved by gardening enthusiasts for its unique stick-like branches. In addition to the traditional soil cultivation method, hydroponic care has gradually gained popularity in recent years. This article will delve into the feasibility of hydroponic cultivation of Euphorbia stricta and systematically explain the key points of the entire process of transitioning from soil to water.
Analysis of the Feasibility of Hydroponic Cultivation
Root Characteristics and Adaptability
Euphorbia stricta has a well-developed aerial root system, theoretically possessing the physiological basis for hydroponic cultivation. Experimental data show that healthy mature plants have a root germination rate of 73% in a 20-25°C environment. However, it is important to note that its fleshy stems are sensitive to moisture, and the hydroponic container must maintain 30% air contact.
Full Process of Transitioning from Soil to Hydroponic Cultivation
Plant Pre-treatment Techniques
After removing the plant from its original pot, it requires three-level treatment: 1) rinse with clean water to retain the original fine roots, 2) trim decayed tissue to retain healthy main roots, 3) let it dry in the shade for 48 hours to form a healing layer. It is recommended to soak in a 800x solution of carbendazim for 15 minutes to prevent infection.
Container Selection Standards
It is recommended to use transparent glass containers with a diameter of 8-12 cm, with a material light transmission rate of >85% to facilitate photosynthesis. The height of the container should be in a 2:1 ratio with the height of the plant's root neck, and the water level should be controlled 1 cm below the root neck.
Core Points of Hydroponic Care
Water Quality and Nutrition Management
Use tap water that has been standing for 3 days, change it every 10 days and add 3 drops of specialized hydroponic nutrient solution. During the high-temperature summer season, supplement with a 0.1% ferrous sulfate solution every week to prevent yellowing.
Environmental Control Strategies
Maintain a diffused light environment, with light intensity controlled between 8000-12000Lux. Keep the temperature between 18-28°C, and the water temperature in winter should not be lower than 15°C. It is recommended to clean the algae off the bottle walls with a cotton swab monthly.
Through scientific hydroponic management, Euphorbia stricta can maintain its ornamental value for 2-3 years. However, it is important to note that the plant's resistance to adversity is 30% lower than in soil cultivation, and it is recommended to transition back to soil cultivation in the spring every year for rejuvenation. Mastering the correct method can achieve diversified cultivation of this unique plant.
