What to Do About Frost's Morning Root Rot
As a high-quality variety of the Sedum genus, Frost's Morning is loved by flower enthusiasts for its blue-pink gradient leaves. However, root rot issues frequently occur during maintenance, becoming a planting pain point. This article will systematically analyze the coping strategies for Frost's Morning root rot, from pathological mechanisms to treatment solutions.
In-Depth Analysis of the Causes of Frost's Morning Root Rot
Imbalance in Water Metabolism Leading to Rot
As a hybrid descendant of Star美人 and Guanghan Palace, Frost's Morning has perfectly inherited drought-resistant genes. Its root system has a water-storing cell layer structure. When watering frequency exceeds the plant's metabolic capacity (recommended 15-20 days/time in spring and autumn), cells continuously expand and rupture, creating a breeding ground for pathogens such as Fusarium.
Double Attack of Soil Pests
Root mealybugs secrete honeydew when刺吸汁液 through their mouthparts, causing sooty mold that clogs stomata; root-knot nematodes form giant cell tumors through mechanical damage, paralyzing the conducting tissue. The wounds caused by both can also increase the risk of Pythium infection.
Full Process of Treating Frost's Morning Root Rot
Accurate Surgical Debridement Operation
After removing from the pot, use a sterilized scissors to make an oblique cut 2cm from the edge of healthy tissue, preserving the white vascular bundles. Apply sulfur powder or charcoal ash to the incision, place it in a scattered light and well-ventilated area to dry for 72 hours, and only pot it after callus tissue has formed.
Systematic Reconstruction of Maintenance Plan
When the main root rot exceeds 70%, it is necessary to perform a topping cutting: retain the top 5-7 leaf disks, soak in carbendazim solution, and insert into a matrix of珍珠岩:蛭石 = 3:1. Maintain an environmental humidity of 60%-70%, and new aerial roots can be seen after 15 days.
Daily maintenance is recommended to use the "dry-wet cycle method": wait for the pot soil to completely dry for 3 days before watering thoroughly in spring and autumn; water slightly once a month during the high-temperature dormancy period in summer; maintain the matrix absolutely dry in winter. Combined with specialized soil with a particle ratio of 70%, it can effectively prevent the recurrence of root rot.
