Care Measures for Euphorbia stricta
Euphorbia stricta, with its unique and fleshy shape, is loved by gardening enthusiasts for its distinctive stem morphology. To cultivate a healthy and robust Euphorbia stricta, it is necessary to master scientific care methods and use specialized cultivation substrates. This article will systematically analyze key cultivation techniques from light management to soil formulas.
Four Key Elements of Scientific Care for Euphorbia stricta
Light Intensity Control Scheme
Euphorbia stricta has typical desert plant characteristics, and it is recommended to ensure 6-8 hours of direct sunlight daily. Full sunlight care can be provided in spring and autumn, while 30% of strong light should be filtered with a shading net from 11 to 15 o'clock in summer. When grown indoors, a south-facing windowsill can provide light intensity up to 20000-30000Lux, fully meeting growth requirements. During winter, the pot should be regularly rotated to prevent the branches from bending towards the light.
Intelligent Watering Management System
Adopt the "dry-wet cycle" method for watering: ① Bamboo Stake Detection Method: Insert a bamboo stake 2/3 into the potting soil, and water when no moisture is present when pulled out; ② Weight Judgment Method: Replenish water when the weight of the container is reduced by 2/3. Water thoroughly every 15 days during the growing season of spring and autumn, once a month during the high-temperature dormant period in summer, and stop watering during winter. It is recommended to use a narrow-spout watering can to slowly pour water along the edge of the pot, avoiding water accumulation in the leaf center.
Nutrition Supply Strategy
Apply a special fertilizer for succulents every 20 days during the growing season (April to October), diluted at a ratio of 1:1500. Do not fertilize new plants for the first 3 months after potting, and mix 5% decomposed sheep manure into the substrate as a base fertilizer when repotting. Ensure the nitrogen-phosphorus-potassium ratio is controlled at 3:6:9 to promote the lignification of stems.
Specialized Cultivation Substrate for Euphorbia stricta
Soil Physical Properties Requirements
The ideal cultivation medium should meet: ① Porosity > 35% to ensure breathability, ② Water-holding rate < 25% to prevent root rot, ③ Bulk density 0.8-1.2g/cm³. Suggested formula: Red Jade Soil 40% + Volcanic Rock 20% + Coarse River Sand 15% + Coconut Husk 15% + Rice Hull Charcoal 10%, add 50g of sulfur powder per cubic meter to adjust the pH to 6.0-6.5.
Repotting Operation Norms
Repotting is required every 24 months: ① Choose a breathable ceramic pot 5cm larger than the original pot; ② Retain the main root length of 8-10cm when pruning, and cut off capillary roots with a diameter < 2mm; ③ Let the wound dry for 3 days before potting; ④ Avoid watering within 7 days after repotting. The best time for repotting is in spring when the temperature is stable above 18°C.
By precisely controlling light, maintaining a scientific watering rhythm, and using a special cultivation substrate, the ornamental value of Euphorbia stricta can be effectively enhanced. It is recommended to prune the branches every quarter, adjust the particle soil ratio, and can cultivate thick stems up to 3cm in diameter. Regularly observe the plant's condition and adjust the care plan in a timely manner to keep Euphorbia stricta in the best growth state.
