What's wrong with the rotten roots of peony spider plants
As a hanging plant that is deeply loved by flower lovers, the problem of rotten roots of peony spider plants often causes headaches for conservators. Through the analysis of the four core causes, this article teaches you to systematically master the treatment and prevention methods of rotten roots, so that the plants can return to a healthy state. Analysis of the four major causes of peony spider root rot. Data on root suffocation caused by excessive watering shows that 70% of root rot cases are due to improper water management. When the humidity of the pot soil continues to be greater than 80%, the roots will be ethanol poisoned due to hypoxia. It is recommended to use the bamboo stick detection method: insert the bamboo stick into the soil for 5 minutes and then pull it out. If it carries unearthed grains, water control needs to be carried out. Remove the pot immediately after discovering that rotten roots are found, soak them in 800 times carbendazim solution for 30 minutes, air the roots for 24 hours before replacing the breathable substrate. Typical symptoms of fertilizer damage burning roots are scorched leaf tips accompanied by soil frost. It is recommended to use an EC value testing pen to keep the EC value of the substrate between 1.2-1.8mS/cm. If fertilizer damage has occurred, wash the substrate with siphon method: immerse the flowerpot in clear water, the water level is 2 cm higher than the pot soil, continue to soak for 40 minutes, and repeat it 3 times to remove 80% of the excess fertilizer. Experimental data on the three major misunderstandings in flower pot selection shows that the water permeability rate of pottery pots is 3.2 times that of plastic pots. It is recommended to use a veg-fired pottery basin with a diameter of 3 cm larger than the root system, and lay a 3 cm thick ceramsite drainage layer on the bottom. Pay special attention to avoid using glazed porcelain pots, whose breathability is only equivalent to 60% of that of plastic pots. Low temperature and high humidity double damage When the environmental temperature is less than 10℃, the watering frequency should be reduced to once a month. In case of freezing damage and rotten roots, the root system must be pruned and blackened in time and the wound should be treated with plant ash. It is recommended to use double-layer insulation method in winter: the outer layer is covered with insulation bags and the inner layer is filled with pine scales, which can increase the root temperature by 3-5℃. After the successful treatment of the peony spider rejuvenation maintenance plan, the "three control" principles should be followed: control light (scattered light for 4 hours a day), control humidity (maintain 50-60% air humidity), and control nutrients (stop applying solid fertilizer for the first 3 months). Irrigation roots with 1000 times of seaweed essence every month can increase the germination rate of new roots by 40%.
