Will the roots rot if I pour too much green water
As a star player in indoor green plants, green radish is deeply loved for its easy maintenance characteristics. However, many growers often fall into the misunderstanding of watering, especially the question of "Will the roots rot if you water too much?" This article will deeply analyze the key points of root maintenance of green radish and provide systematic solutions from the causes of rotten roots to treatment solutions. Analysis of the causes of rotten roots of green radish, water accumulation and hypoxia mechanism When the amount of watering exceeds the absorption capacity of the plant, the water on the bottom of the basin forms a closed water film, and the continuous immersion of the roots causes cells to suffocate. Data shows that the roots of green radish begin to rot within 48 hours in a stagnant environment, and the rot rate can reach 65% in 72 hours. Environmental factors combined with low temperatures in winter (<15℃) will aggravate the hazard of water accumulation, and the water evaporation at this time is only 30% of that in summer. When the air humidity in the rainy season is greater than 80%, special attention should be paid to the frequency of water control. Emergency drainage steps of the entire process of green radish rot root treatment. Immediately tilt the flowerpot to dump excess water after water is found, and use a cotton swab to dry the remaining water stains in the hole on the bottom of the basin. It is recommended to use siphon method to extract deep stagnant water. After root repair surgery, the principle of "three cuts and three retention" is adopted: cutting rotten roots to leave the roots blank, cutting black stems to leave green stems, cutting diseased leaves to leave new buds. It is recommended to soak in hydrogen peroxide (concentration 3%) for 15 minutes during disinfection, which has a better germicidal effect than carbendazim. Scientific watering system plan The four-season watering rules are maintained for 5-7 days per time in spring and autumn, shortened to 3-4 days per time in summer, and extended to 10-15 days per time in winter. You can use a soil hygrometer to replenish water when the value is less than 30%. The substrate improvement plan recommends a ratio of perlite + coconut bran + legular soil of 2:3:5, and the water permeability is increased by 40% compared with ordinary garden soil. The basin is a pottery basin with ventilation holes, and the bottom is covered with a 3cm-thick ceramsite drainage layer.
By establishing a scientific watering system, combined with substrate improvement and regular observation, the probability of rotten roots of green radish can be effectively reduced by 90%. It is recommended to conduct a monthly root health check to detect early and deal with early, so that green radish will always remain vibrant.
