How to deal with the rotting bark of a wealth treeThe wealth tree, as a star variety in the home green plant industry, is loved for its unique shape and auspicious meaning. However, when the trunk shows symptoms of rotting and peeling, it often leaves growers at a loss. This article will systematically analyze the causes of bark rot and provide a full-process solution from diagnosis to repair.I. Three main causes of bark rot on wealth trees1.1 Improper watering leads to pathological changesExcessive watering is the primary factor leading to root hypoxia and rot. When the soil moisture content exceeds 70%, the continuous immersion of the roots can cause cell necrosis, which is manifested as brown water-stained spots on the base of the trunk. Long-term water deficiency can also cause conduit blockage, forming dry rot ulcers.1.2 Misoperation of fertilizationIncorrect operations such as direct contact of high-concentration fertilizers with the trunk, unripe organic fertilizers, and continuous topdressing in winter can lead to chemical burns and microbial infections. Data shows that 35% of bark rot cases are related to excessive fertilization.1.3 Defects in matrix configurationClayey and compact garden soil can impede root respiration. It is recommended to use a ratio of perlite:coconut bran:decomposed leaf soil = 3:4:3. Long-term soil replacement can cause salt accumulation, which will also damage the epidermal protective layer.II. Four-step emergency repair plan2.1 Standard for lesion cleaningUse a sterilized utility knife to scrape away the decayed tissue at a 45-degree angle until healthy cambium is exposed. Apply a wound healing agent containing kasugamycin to the wound surface, reapplying every 72 hours.2.2 Precise water and fertilizer controlAfter entering the repair period, adopt the "dry-wet" watering method, maintaining air humidity between 60%-75%. Apply a liquid fertilizer with a phosphorus-potassium ratio of 70%, controlling the EC value between 1.2-1.5mS/cm.2.3 Matrix update and upgradeChoose陶粒 (陶粒 = ceramsite) with a diameter of 3-5mm as the base, mixed with breathable materials such as pine scales and activated carbon. After potting, place it in a diffused light area for 14 days and prohibit fertilization during this period.III. Key points for long-term maintenance3.1 Intelligent environmental monitoringConfigure a soil moisture meter and a temperature and humidity meter, maintaining temperatures above 15℃ in winter and avoiding direct sunlight in summer. Spray with a 800x solution of carbendazim every month for preventive measures.3.2 Periodic health checkConduct "look, touch, and test" every quarter: observe the color of the epidermis, feel the hardness of the xylem, and test the soil pH (ideal range 5.8-6.5).Through a scientific maintenance system, not only can existing bark rot issues be effectively repaired, but long-term preventive mechanisms can also be established.
