How to Revive a Lucky Bamboo with Half Rotten Stem
As a common ornamental leaf plant in offices and homes, the lucky bamboo is loved for its upright shape and auspicious meaning. However, when the stem shows signs of local rot, many caregivers are at a loss. This article will systematically explain the entire process of dealing with a rotten stem, combined with specific operational diagrams, to help your lucky bamboo regain its vitality.
Process for Treating a Rotten Stem of Lucky Bamboo
Precise Pruning of Rotten Tissue
When brown, soft rot areas appear on the stem, it is necessary to immediately clean them using gardening shears that have been disinfected with alcohol. It is recommended to cut 0.5cm beyond the edge of healthy tissue to ensure the complete removal of the infection source. During the operation, pay attention to the color of the cut surface, as healthy bark should be light green and free of sticky fluid secretion.
Thorough Disinfection and Fungicide Treatment
After pruning, a compound disinfectant solution made by mixing carbendazim and thiophanate-methyl in a 1:1 ratio is more effective. Keep the solution concentration at 800-1000 times, and use a cotton swab to assist in cleaning the wood crevices during wound immersion. After the treatment, hang it to dry for 24 hours to avoid secondary damage from direct sunlight.
Comprehensive Inspection of the Root System
After removing the pot, carefully comb the fine roots and cut off the black, soft diseased roots. The remaining robust main roots can be dipped in rooting powder containing indole acetic acid to promote the growth of new roots. Special attention should be given to the root collar junction, where annular rot requires special treatment.
Precautions for Replanting and Care
Use a mixed substrate of peat soil: perlite: vermiculite in a ratio of 3:1:1 to ensure good drainage and aeration. Place the pot in a scattered light environment at 25°C, keeping the substrate slightly moist but not waterlogged for the first two weeks. After new buds sprout, foliar fertilizer can be applied, but avoid touching the wound.
With the above systematic treatment plan, over 80% of腐烂 lucky bamboos can recover. In daily maintenance, it is necessary to control the watering frequency, maintain ventilation in the environment, and regularly check the condition of the stem. If signs of secondary infection are found, repeat the disinfection process and change the potting soil in a timely manner.
