Euphorbia cyathophora propagation methods
Euphorbia cyathophora is a cherished variety among succulent enthusiasts for its unique patterned morphology. Mastering its propagation techniques not only preserves the plant's characteristics but also provides the joy of horticultural cultivation. This article systematically analyzes the operational details of the two main propagation methods, cutting and grafting, with real photo illustrations to help you easily master the cultivation tips.
Complete analysis of Euphorbia cyathophora cutting propagation process
Best cutting timing selection
Perform the cutting in spring from March to May when the day-night temperature difference is stable at 18-25°C. At this time, the plants are in an active growth period, and the formation of callus is fast, effectively increasing the survival rate to over 85%. Avoid operating during the rainy season to prevent fungal infection at the cut.
Standardized stem section treatment
Select the top 3-year-old healthy stem sections and cut 8-12cm stem segments using a knife disinfected with alcohol. The white juice needs to air-dry for 48 hours to form a protective film, which can be combined with the application of wood ash to accelerate scab formation and reduce the risk of bacterial infection.
Substrate formula optimization
Use a mixture of perlite: vermiculite: coarse sand = 2:1:1 to ensure a porosity of over 40%. Sterilize the substrate with high-temperature steaming before use and maintain the moisture content between 30%-40%, as excessive moisture can lead to decay.
Intelligent environmental control
After cutting, place in a scattered light environment and equip with a thermometer and hygrometer for real-time monitoring. Maintain air humidity at 70% for the first 15 days, and then gradually reduce to natural conditions after 20 days. During the root development period, water with a diluted rooting hormone solution (1:1000) every 10 days.

Selection criteria for rootstock
Choose a robust霸王鞭 (霸王鞭 is a plant name, possibly meaning "spear whip") from the same Euphorbiaceae family with a diameter of over 1.5cm, free from diseases and pests. Before grafting, reduce water intake for 3 days to make the rootstock slightly dehydrated, which improves the adhesion of the scion.
Operation specifications for cleft grafting
Use a 45-degree oblique cut on the top of the rootstock, and quickly insert the wedge-shaped scion. Wrap with multiple layers of medical breathable tape and cover the outside with PE plastic wrap to form a humid microenvironment. Avoid direct sunlight for 10 days after grafting.
Scientific management during the healing period
Maintain a day-night temperature difference of 8-10°C to stimulate the growth of callus, and after 20 days, gently touch the scion to check the adhesion. After successful grafting, gradually increase the light intensity as new buds emerge, and apply phosphorus-potassium fertilizer monthly to enhance the color of the patterns.
Through systematic operation and meticulous management, both cutting and grafting can achieve an ideal survival rate. It is recommended for beginners to start with spring cutting and then try grafting techniques after mastering the plant's characteristics. Regularly observe the plant's condition and adjust the maintenance plan in a timely manner to allow Euphorbia cyathophora to form a spectacular clustering landscape within 3-5 years.
