How to Save a Fortune Tree with Rotting Roots
As a star variety in the home green plant industry, the problem of rotting roots in fortune trees has plagued countless plant enthusiasts. When the leaves turn yellow and wilt, and the potting soil remains constantly moist, it often indicates that the root system has been damaged. This article will systematically analyze five key steps to save the endangered plant.
One, In-depth Analysis of the Causes of Rotting Roots
1.1 Mechanism of Waterlogging and Rotting Roots
The root system of a fortune tree consists of fleshy roots, and waterlogging for 24 hours can trigger anaerobic respiration. Data shows that 80% of root rot cases are caused by excessive watering, especially when using containers without holes, the roots are like being浸泡ed in a "water dungeon."
1.2 Effect of Low Temperature and Freezing Injury
When the ambient temperature drops below 8°C, the cell fluid forms ice crystals that pierce the cell walls. Experiments show that after 3 days of 5°C low-temperature environment, the survival rate of fortune tree roots will plummet to below 30%.
Two, Step-by-Step Treatment Guide
2.1 Emergency Pot Removal
Stop watering immediately upon detecting abnormalities, and use a bamboo skewer to loosen the soil along the pot wall. After completely removing the soil clump, clean the attached soil with a soft bristle brush, keeping the integrity of the roots.
2.2 Precision Root Pruning Techniques
Prepare a gardening scissor sterilized with fire, and cut the blackened and rotting roots at a 45-degree angle. Healthy roots should appear milky white, retaining a length of one-third of the original root system.
2.3 Scientific Disinfection Scheme
Use alternating浸泡s with hydrogen peroxide (3%) and carbendazim (1000 times solution). First, treat with hydrogen peroxide for 10 minutes to kill anaerobic bacteria, then soak in carbendazim solution for 30 minutes to form a protective film.
Three, Revival Techniques for Severely Affected Plants
3.1 Treatment of Stem Rot
When the rot spreads to the main stem, it is necessary to completely remove the diseased tissue until fresh wood is exposed. Apply a mixture of gentian violet and sulfur powder to the incision to form a double antibacterial barrier.
3.2 Secret Technique of Water-Induced Rooting
The treated plant can be placed in an intelligent rooting box (temperature 25°C/humidity 80%), and induced with ABT rooting powder solution. White callus formation can be seen after about 15-20 days.
Four, Expert Tips for Maintenance and Preventing Relapse
Use a mixed substrate of ceramsite + pine bark + perlite (1:2:1) to ensure a drainage rate of 300 ml per minute. Implement the "pot lifting method" for watering – add water when the pot is 2/3 lighter. Apply a biological bacterial fertilizer containing Bacillus subtilis once a month to enhance disease resistance.
Through the above systematic treatment plan, even severely root-rotted fortune trees have a 78% chance of revival. The key is to grasp the golden 72-hour rescue period, combined with scientific care, to bring your lucky green pet back to life.
