What should I do if Dayantong is rotten?
As a much-loved indoor ornamental flower, Dayantong captures the hearts of many flower lovers with its velvet texture and gorgeous flowers. However, during the maintenance process, many flower lovers will encounter the thorny problem of bulb rot. This article will systematically analyze the causes of Dayantong rotten balls and provide detailed rescue plans to revitalize your love flowers. Analysis on the causes of rotten balls of Dayannia japonica improper selection of soil medium The use of sticky and hardened cultivation substrates is the primary culprit of rotten balls of Dayannia japonica japonica. This type of soil has poor drainage and air permeability, and is prone to stagnant water after watering, causing the bulbs to be in a state of hypoxia for a long time. It is recommended to use a mixed formula of humus soil + perlite (2:1) to ensure normal respiration of the roots. There are misunderstandings in watering methods. 60% of rotten ball cases are caused by excessive watering. Dayantong has water-storing bulbs, and daily maintenance must strictly follow the principle of "seeing dry, seeing wet". During the winter hibernation period, water control is more necessary to maintain micro-tide in the substrate. The first step of the practical guide for the six-step rescue method: Accurately judge the degree of decay and gently pinch the bulb to confirm the hardness and softness. If the overall softening exceeds 1/3, it is recommended to give up. Retain the bulbs with elastic outer layers and unrotted center (survival rate of more than 85%). Step 2: Scientific disinfection and treatment After using 75% alcohol to disinfect the knives, completely remove the rotten tissue to healthy parts. Apply carbendazim powder to the wound surface and place it in a ventilated and cool place to dry for 1.5 hours to form a protective scab. Step 3: Intelligent hair root medium selection recommends using water moss as the root matrix, and its water holding rate is stable at 60%-70%, which can maintain humidity and avoid water accumulation. The treated bulbs are half-buried in moist water moss, and covered with a transparent container to maintain a microenvironment. The key points for later maintenance are to gradually increase the light intensity after new buds germinate, and the transition period is controlled at about 15 days. When the new root system reaches 3 cm, it can be transplanted to a conventional cultivation substrate. During daily maintenance, pay attention to maintaining the temperature difference between day and night at 8-10℃, and supplement phosphorus and potassium fertilizers once a month to promote the rejuvenation of the bulbs.
Through scientific rescue procedures and refined management, the survival rate of Dayantong rotten balls can be increased to more than 90%. It is recommended to check the status of the bulbs every quarter and adjust the maintenance plan in time to keep your plants healthy and vibrant.
