What should I do if the fleshy roots and the poles are black?
Succulent plants are very popular for their unique shape and easy-to-maintain characteristics, but they often encounter the thorny problem of blackening of root rods during maintenance. This phenomenon often indicates damage to the root system, which may lead to plant death if not intervened in time. This paper uses systematic solutions to help growers accurately identify the root cause of problems and implement effective treatment. Reason for blackening fleshy poles: Diagnosis Excessive moisture leads to suffocation black rot. Excessive watering is the primary cause of fleshy black poles. Its fleshy roots will quickly lose their respiratory function in a stagnant water environment. By observing the basin soil hygrometer or finger penetration method, be vigilant when the substrate moisture content exceeds 30%. It is recommended to use a permeable substrate with perlite accounting for more than 40% and combined with a red pottery basin with drainage holes at the bottom, which can reduce the risk of root rot by more than 50%. Chemical burns caused by fertilizer damage Excessive nitrogen fertilizer can cause an imbalance in cell osmotic pressure, manifested by browning of roots and accompanying leaf transparency. Experimental data show that the concentration of special meat-rich fertilizer should be controlled below 2000 times liquid, and it should be applied once a month during the growth period. Double water leaching should be carried out immediately after the fertilizer damage is discovered. If it is serious, new soil containing vermiculite needs to be replaced to rebuild the root environment. First Aid Operation Guide for Meat Black Rot Physical Intervention Trilogy When local black spots appear on the pole, a three-step treatment method is used: ① Alcohol disinfection knives are used to remove the diseased tissue;② Apply charcoal powder to the wound surface to isolate the bacteria;③ Place them in a cool place at 26℃ to dry roots for 72 hours. This method can increase the survival rate of cuttage to more than 85%. New regenerative cultivation technology After treatment, the top healthy stem segments are inserted into a root promoter containing 500ppm gibberellin and soaked for 10 minutes, and then transplanted into a mixed substrate of volcanic rock: peat soil =3:1. Maintaining a temperature difference of 25 ° C during the day/18 ° C at night, combined with scattered light for 4 hours a day, new roots usually germinate within 15-20 days. Build a meaty maintenance and prevention system and establish a periodic inspection system, using a soil moisture detector to check the moisture content every week. Maintain a 10-15-day watering cycle in spring and autumn, and extend the high temperature period in summer to 20 days. It is recommended to configure a broad-spectrum fungicide containing copper-containing preparation and spray it monthly to form a protective film, which can reduce the probability of fungal infection by 70%.
Through scientific diagnosis and precise intervention, the problem of blackening of fleshy poles is completely controllable. The key is to grasp the three principles of "early detection, rapid treatment, and emphasis on prevention" and combine modern gardening technology to allow even severely black-rotting plants to regain their lives. It is recommended to collect the operation flow chart provided in this article and establish a fleshy health management file so that each plant can show its best condition.
