What are the causes and treatment methods of the rotten roots of "lazy plant" tiger skin orchid?

Tiger skin orchid, also known as tiger tail orchid, thousand-year-old orchid, because of its easy maintenance, strong adaptability, and can be in harmony with a variety of household styles, also known as lazy plants by flower friends. However, in the process of breeding tiger orchid, there may also be the problem of rotten roots, so what are the causes and treatment methods of rotten roots?

First, the reason for the rotting root of Tiger Pilan

1. Overwatering

The root system of tiger orchid is underdeveloped and has fleshy roots, so it is often planted shallowly, while some flower friends are watered too much, and the water in the pot soil can not be volatilized in time, which leads to rotten roots over time.

2. the soil has not been changed for a long time.

Tiger Pilan usually changes the soil every two years, if there is no soil for a long time, the nutrients in the soil are exhausted, and the air is scarce, hindering the breathing of the roots, which will cause rotting roots. In addition, long-term fertilization, fertilizer effect can not be completely volatile, will accumulate in the basin soil, seriously affecting the growth of roots.

3. Poor ventilation in the growth environment.

Tiger Pilan does not require high lighting, but the environment must be well ventilated. If you are in a muggy state for a long time, the leaves can not absorb water, which will also affect your root growth.

4. Diseases and insect pests

In the process of growth, tiger skin orchid will be damaged by root rot and nematodes, resulting in root injury and rot.

Second, the treatment of the rotten root of Tiger Pilan.

1. Change the basin frequently

Change the basin every two years, change half of the new soil when changing the basin, and disinfect the soil in the sun or irrigate fungicides. Select the soil rich in humus which is fertile and loose and has good drainage.

2. Less watering

The growth of tiger skin orchid does not need more water to ensure that the soil in this basin is moist. If you do not know how much water is poured, you can use the immersion basin method to water, which can reduce the stagnant water in the basin. Reduce watering in winter.

3. Replant

Tiger Pilan which has rotten roots can be replanted in the pot. First of all, clean up the rotten part of the root, if possible, use fungicides such as carbendazim, then dry in a cool place and replant and take root (it is recommended to use plain sand + vermiculite + peat to take root in the cutting medium).

If the rotten roots of tiger skin orchid are serious and the soil balls have a strange smell, they must wash off the persistent soil, cut off the rotten roots, replant them, and soak the roots with potassium permanganate-800 times solution before planting, which can be preservative and promote roots. Leave the seedlings in a cool place for a week after planting, during which time fertilizer is stopped and water is controlled.

Warm reminder: it is now winter, tiger skin orchid culture gets a "high-risk period", in order to prevent trouble, even if the environmental temperature is higher, tiger skin orchid should also be controlled by water, otherwise in the case of a sudden lower temperature, the tiger skin orchid plant will also rot. Therefore, the phenomenon of plant decay can be avoided by controlling watering and keeping the basin soil slightly dry in winter.
