What about the rotten roots of potted orchids?

The flowers of Cymbidium are bright and have high ornamental value, but the cultivation of Cymbidium is not so easy, so it is necessary to master strong breeding technology. The root rot disease of Cymbidium can occur all the year round, but it mostly occurs in summer. It is easy to rot if you do not pay attention to water control. It is a great pity to let it go. Don't be discouraged. It will come back to life after treatment. Let's take a look at the causes and treatment of the rotten roots of Cymbidium.

Analysis 1: the permeability of nutritious soil is not good, and the soil is overripe or overborn.

Solution: the oak leaves used before the preparation of nutritious soil should not be over-rotted or over-raw.

Analysis 2: improper fertilization.

Solution: orchid fertilizer should not be too much, otherwise heat will be generated to burn the root system and cause rot.

Analysis 3: too much watering.

Solution: watering should also be appropriate, too much will make the nutrient soil water content is too large, poor permeability, root breathing difficulties, resulting in rotting roots. Be careful not to water the heart of the orchid.

Analysis 4: put nutritious soil carrier bacteria to propagate, high-temperature and humid environment to prevent bacterial reproduction, bacterial infection, in this environment a large number of bacteria multiply, directly invade the root system and cause rotting root.

Solution: high temperature in summer and autumn, excessive fertilization and watering, it is easy to appear root rot. It is necessary to strengthen cooling and ventilation, control man-made mechanical injuries in high temperature season, spray drugs in time to prevent insect bites, and reduce the reproduction and spread of germs. Sometimes the pathogen overwinters in the soil with the disease residue, and the flower soil must be sterilized when changing the soil in spring.

The treatment of rotten roots of Cymbidium: if you find that there are rotten roots, you should be treated immediately. Take out the plant, remove the rotten root, rinse the root with 1% potassium permanganate water for disinfection, or apply some charcoal powder to the affected area and sun the root in the greenhouse for about 30 minutes. If the rotten root is more than 50% or all rotten, use the above method to treat and then use river sand to promote the root. The root-promoting temperature should be higher than the normal temperature, which is generally controlled at about 22-30 ℃, so that new roots will grow after about 2 months, and then transplanted to the nutrient soil basin.

The reason why the gentleman orchid sucks?

The main results are as follows: 1. High temperature, high humidity and poor ventilation make the fleshy root of the plant rotten easily.

2. too much watering, high water content of nutritious soil, poor air permeability, long-term soaking of roots by water, resulting in discoloration and decay of roots.

3. Hypertrophy, the fertilizer in the nutritious soil is not fully fermented, resulting in root rotting caused by heating and burning, improper fertilization during the growing period, excessive amount of fertilizer, resulting in fertilizer contact with the root, resulting in root burning, affecting the root absorption capacity, root tissue is destroyed and rotten root, we should pay attention to the diligent application of thin fertilizer.

How to deal with the rotten roots of gentleman orchids?

The main results are as follows: 1. If the root of Cymbidium is rotten, it can be alleviated by changing soil, controlling watering, proper illumination and so on.

2. The rotten heart is not very serious. Observe whether the tender leaves on both sides of the center are rotten. If the leaves are rotten, remove the rotten leaves immediately, absorb the excess water with toilet paper or cotton, and then transfer them to a drier environment.

3. The solution to the rotten roots of Cymbidium

1). Cleaning of rotten roots

Plant the rotten roots from the flowerpot, gently peel off the soil, then rinse the roots with water and clean the rotting roots with scissors.

2). Disinfection of roots

Soak the cleaned roots in 0.1% potassium permanganate solution for 5 minutes, then apply a little sulfur powder or plant ash or carbendazim, and then dry in a cool place (about 2 days).

3) replanting

After drying, the gentleman orchid is planted in the sandy soil to promote the germination of new roots. after planting, you should control watering, do not dry and do not water, so as not to rot the roots again, and put them in a cool and ventilated place. the ground is often sprinkled or foliar spray to maintain a certain amount of air humidity and can be re-rooted in about 2-3 months. The rotten roots of Cymbidium will cause irreparable losses to the growth and flowering of the plant, no matter how they are rescued in time, and it will take quite some time to fully restore their growth. Therefore, at ordinary times, we should do a good job in prevention as far as possible to avoid the occurrence of rotting roots.
