What should I do if I water too much silk?
As a representative variety of succulent plants in the Crassulaceae family, Wujuan silk is favored by gardening enthusiasts due to its unique lotus seat shape. However, the most common problem during the maintenance process is the crisis of rotten roots caused by excessive watering. This article will systematically analyze the four major first aid plans and preventive measures. 1. Strengthen ventilation treatment 1.1 The principle of air circulation When the water content of the basin soil exceeds 60%, the root system will produce ethanol poisoning due to hypoxia. It is recommended to move the plants to a balcony that is transparent from north to south, and cooperate with small circulating fans to form air convection to accelerate the evaporation of water. 1.2 Seasonal precautions should be maintained above 15 ° C in winter before ventilation to avoid frostbite caused by cold air. You can open windows from 10:00 to 14:00 on sunny days, and set thermal insulation foam boards on the bottom of the basin. 2. Loose soil drainage operation 2.1 Select to use a stainless steel gardening stick with a diameter of 3mm for loosening tools, and insert the loose soil obliquely at a 45-degree angle along the basin wall to a depth of 2/3 of the basin height. Never use sharp iron to damage capillary roots. 2.2 The drainage system is optimized to lay a 2-cm-thick volcanic rock grain layer at the bottom of the basin, combined with a mixed matrix with a perlite content of 30%, which can increase the drainage efficiency by 40%. 3. Soil replacement plan 3.1 The new soil formula is recommended to be prepared in the ratio of peat soil: red jade soil: vermiculite =3:5:2, and 5% bone meal is added to supplement calcium. It is recommended to control the pH value between 6.0 and 6.5. 3.2 Root pruning and disinfection process After cutting off the black and soft rotten roots, soak them in a 1000-fold carbendazim solution diluted for 20 minutes, and dry the roots for 48 hours until the wound scabs before placing them in the pot.
Through the above-mentioned systematic rescue measures and the later use of the "dry and wet" watering method (7-10 days per time in spring and autumn, and 15 days per time in summer), the recovery rate of house-rolled silk can reach more than 85%. It is recommended to regularly check the humidity of the pot soil and use bamboo stick testing method to judge watering timing.
