How to Care for Rong Sushi
As a star variety in the succulent plant world, Rong Sushi is highly favored for its unique leaf shape and gradient colors. This plant, native to South Africa and belonging to the Crassulaceae family, is easy to care for, but achieving an excellent potted plant state requires mastering scientific methods. This article will systematically analyze the essential care tips for Rong Sushi, from environmental control to pest and disease prevention.
Management of Rong Sushi Growth Environment
Accurate Temperature and Humidity Control
The optimal growth temperature should be maintained between 15-25°C, and it can be kept outdoors in spring and autumn to promote coloring. When the temperature exceeds 30°C in summer, it should be moved to a shady and well-ventilated area, and misting can be used to maintain 50% air humidity. In winter, ensure the temperature in the care environment is greater than 5°C, and it is recommended to bring it indoors in cold regions for wintering.
Adjusting Light Intensity
Ensure 4-6 hours of scattered light daily, and it can be exposed to full sunlight in spring and autumn to promote the formation of red leaf edges. From 10:00 to 15:00 in summer, 30%-50% shading is needed, using shade nets to avoid sunburn. In winter, it can be placed on a south-facing windowsill for additional light, with even better results when combined with plant grow lights.
Key Points of Rong Sushi's Daily Care
Scientific Watering Plan
Use the "dry and wet" method, keeping the soil slightly moist during the growing season in spring and autumn, watering twice a month during the summer dormant period, and once a month in winter. It is recommended to use a narrow-mouthed pot to slowly pour water along the pot wall to avoid water accumulation in the leaf center. During the plum rain season, elevate the pot to enhance drainage, and it is suggested to add 30% volcanic rock particles to the soil.
Reasonable Fertilization Schedule
How to Care for Rong Sushi
When potting, mix bone meal as a base fertilizer, and apply a diluted 2000-fold liquid fertilizer for succulents every 60 days during the growing season. From September, stop applying nitrogen and increase phosphorus and potassium fertilizers to promote xylem formation, and stop fertilizing completely in winter. Note the principle of applying thin and frequent fertilization, as fertilizer residue can easily cause root burns.
Advanced Management Techniques for Rong Sushi
Propagation by Cuttings
Select healthy lateral branches for cutting, retaining 3-4 pairs of leaves. After the cut surface dries, insert it into a matrix of perlite:vermiculite (1:1), maintaining a 20-25°C environment, and roots can form within 2 weeks. Transplant when the new sprouts reach 3cm, using 70% granular soil to ensure breathability.
Pruning and Repotting Tips
It is recommended to repot every spring, using a ceramic pot 5cm larger than the original. After removing the dead and old roots, soak in carbendazim for disinfection. New soil formula: red jade soil 40% + peat soil 30% + volcanic rock 20% + rice husk charcoal 10%, with a 3cm layer of ceramsite at the bottom to enhance drainage.
