What to Do About Root Rot in Jade Plant
The jade plant, as a common succulent, is loved for its jade-like green leaves. However, root rot issues frequently occur during maintenance, directly affecting the survival rate of the plant. This article will deeply analyze the causes of root rot in jade plants under both hydroponic and soil cultivation methods, and provide professional-level solutions.
Deep Analysis of the Causes of Jade Plant Root Rot
Key Inducements of Root Rot in Hydroponic Jade Plants
1. Water Pollution: Leaf immersion leads to eutrophication of the water, causing the growth of pathogenic bacteria. 2. Delayed Water Change: When water is not changed for more than 3 days, the dissolved oxygen content drops to a dangerous level. 3. Cut Infection: Direct hydroponic cultivation without disinfection with a fungicide solution after pruning.
Core Factors of Root Rot in Soil-Grown Jade Plants
1. Soil Compaction: When soil porosity is less than 30%, root respiration is obstructed. 2. Waterlogging: Continuous soil moisture above 80% for 3 days can trigger root rot disease. 3. Latent Pathogens: Unsterilized old soil may contain pathogenic sources like Fusarium.
Systematic Treatment Plan for Jade Plant Root Rot
Four-Step Rescue Method for Hydroponic Root Rot
1. Tool Disinfection: Use a scissor heated with alcohol to cut off blackened, rotting roots. 2. Chemical Treatment: Soak in a 0.1% potassium permanganate solution for 20 minutes to sterilize. 3. Environmental Control: Maintain water temperature at 18-25°C and provide 4 hours of sunlight daily. 4. Nutritional Management: Add hydroponic-specific nutrient solution (EC value 1.2-1.5) when changing water.
Secret Techniques for Regenerating Root Rot in Soil-Grown Plants
1. Pot Removal: Gently tap the pot to loosen the soil and retain healthy white roots. 2. Soil Improvement: Use a new substrate mix of perlite:vermiculite:peat in a ratio of 4:3:3. 3. Root Promotion Technique: Apply rooting powder to the cut area and place it in a shaded, well-ventilated area. 4. Potting Care: Maintain 70% air humidity for the first 3 days, then gradually expose to scattered light.
With scientific diagnosis and precise treatment, the survival rate of jade plants with root rot can reach over 85%. Daily maintenance should include changing water twice a week for hydroponic plants and loosening the soil once a month for soil-grown plants. Choosing breathable red陶 pots and using slow-release fertilizer for succulents can effectively prevent recurrence of root rot.
