How to deal with rotten roots of potted flowers?
Root rot of potted plants is the most common and thorny problem during the maintenance process. As a key organ for plant absorption (S-Y), the root system will directly affect the health of the entire plant once it rots. This article will systematically analyze the treatment plan for rotten roots of potted flowers from cause diagnosis to treatment operations. Potted flower rotten roots 3 are mainly caused by excessive watering. Even plants such as green radish and spider plants that like moisture, when the soil water content exceeds 40%, the root system will produce anaerobic respiration due to hypoxia. Data shows that if water accumulates for more than 72 hours, the survival rate of capillary roots will drop by more than 80%. Chemical damage caused by fertilizer burns When the soil EC value exceeds 2.5mS/cm after application of concentrated fertilizer, succulent root plants such as Clivia and succulent will experience osmotic dehydration. It is recommended to use the "three-fold dilution method": dilute the marked concentration by 3 times and apply it. Soil-borne bacteria such as Fusarium and Pythium infected by the bacteria will invade through wounds. Laboratory tests show that the content of pathogenic bacteria in undisinfected old soil can reach 15 times that of new soil. It is recommended to use 800 times carbendazim solution to irrigate roots every quarter for prevention. How to deal with rotten roots of potted flowers?
Four-step Operation Guidelines for Treatment of Rotten Roots Mild (surviving roots>60%): Keep the original soil balls and irrigate the roots with 2000 times of hymoxazole; Moderate (30%-60%): The rotten roots need to be pruned; Severe (surviving roots <30%): Cutting propagation is recommended. Operative root pruning practices use pruning shears sterilized at 121 ° C, obliquely cut 2mm along the healthy tissue, and apply charcoal powder or sulfur powder to the incision. Focus on treating brown lesion tissue at the junction of the main root. Key points for maintenance during the rejuvenation period. After changing the basin, place it in a scattered light environment. Use the dipping basin method to supply water to maintain the air humidity of more than 70%. HB-101 plant vital element (1ml mixed with 2L water) was used to promote new root germination in the first two weeks. Establish a "three inspection" system for preventing pot flower rot and establish a "three inspection" system: check the dryness of pot soil (bamboo stick test method), check the air permeability of bottom holes (dredged twice a year), and check the pH value of the substrate (maintain 5.5-6.5). Combined with physical improvement measures such as ceramsite bedding and pine phosphorus paving, the incidence of root rot can be reduced by 90%.
Through scientific diagnosis and precise treatment, and in conjunction with a preventive maintenance system, even plants with severe rotten roots can regain their lives. It is recommended that flower lovers establish a maintenance log, record data on each watering and fertilization, and use data-based maintenance to bid farewell to rotten root problems.
