Should I cut the black pole of Ping An Tree?
As a common indoor leaf-viewing plant, Pingan tree has its straight branches and shiny leaves that are very ornamental. However, when the branches are found to be blackened, it often leaves growers confused as to whether to cut them. This article will analyze the black pole treatment plan from a professional perspective and provide systematic maintenance guidelines. Judging the timing of pruning black stems of Ping 'an tree, mild black stems treatment plan When the area of the black stems is less than 1/3 of the circumference of the branches, local treatment can be taken: use a disinfectant knife to thoroughly scrape the diseased tissue, apply carbendazim powder to the incision, and then use Waxy sealant protects the wound surface. This stage needs to be coordinated with weekly spraying of mancozeb solution for disease prevention and control. Severe black pole pruning standards If the black rot area exceeds 50% of the diameter of the branch, or if the longitudinal spread exceeds 10cm, it must be cut immediately. When trimming, it is necessary to cut the cut 2cm below the healthy part, and the incision must be disinfected twice with 70% alcohol. The diseased branches that have been cut off need to be sealed to avoid cross-infection. Safe Tree Black Stem Prevention System Scientific watering to avoid root rot adopts the "fingertip detection method": Insert your index finger into the pot soil for 3 cm, and only water if there is no moisture at your fingertips. In winter, a "half-water supply system" is implemented, and each watering is controlled at 200-300ml. In the rainy season, a ceramsite drainage layer needs to be placed on the bottom of the basin. It is recommended to use red pottery pots to enhance air permeability. Light management skills Ping An Tree needs to ensure direct light for 4 hours a day. An automatic rotating base can be set up to allow the plants to receive light evenly. In summer, sunshade nets are used to filter strong light, and in winter, full-spectrum plant fill light is used to maintain the light intensity of 2000-3000lux. The ventilation environment optimization plan installs a timed ventilation system to ensure air circulation more than 3 times a day, each time lasting for 30 minutes. Small circulation fans can be configured in confined spaces to maintain a wind speed of 0.5-1m/s. Regularly wipe the air holes of the leaves with an alcohol cotton pad to maintain smooth breathing.
By accurately judging the timing of pruning and establishing a prevention system, the problem of black stems of safe trees can be effectively controlled. It is recommended to conduct monthly branch health inspections and cooperate with thermohygrometers to monitor environmental data in real time to keep the plants in optimal growth condition.
