What to do with orchid roots when they are rotten, what to do if orchid roots are rotten?

First of all, the rotten part needs to be removed, leaving about 3-5cm of root core, soaked in potassium permanganate solution for about 15 minutes before drying. Prepare suitable pots and planting materials such as soft river sand or moss, and soak them in boiling water to disinfect them. Then the dried orchids are planted in pots filled with river sand, covered and compacted with planting materials, and a layer of moss is spread on the surface to moisturize.

After planting, do not water, just put the plant in a cool place and let it regrow.

Remove all the outer skin of the rotten roots of the orchid, leaving a core about 3-5cm in length. Cut the leaves in half, soak the plants with potassium permanganate solution for about 15 minutes, and then leave them in a cool and ventilated place to dry for about half a day. If there is sun, you can roll the leaves with newspaper, expose the reeds, and place them on a shelf.

It takes about 10 minutes in summer and 1 hour in winter.

1. Prune the root system: Use sterilized sharp scissors to cut off the rotten roots of the orchid, then put it in a cool place, wait for the wound to heal and then replant. 2. Dividing propagation:

If the root system of the orchid is severely rotten, it is necessary to select healthy young plants for transplanting. 3. Causes of root rotten: Orchid root rot may be caused by excessive fertilization and suffering from pests and diseases.

1. Prune the root system

When the root rot of the orchid is relatively mild, only part of the root system is rotten, while the other root systems are relatively healthy. You only need to cut off the rotten roots, place them in a ventilated and cool place after disinfection, and wait until the wound heals before replanting.

2. Dividing propagation:

If the root rot of the orchid is more serious and has not been saved, it can be re-propagated at this time, for example, it can be propagated by dividing the plant, selecting some plants with relatively healthy growth, and planting them in the potting soil, so that the orchid potted plant will grow again soon.

3. The root cause of rot

Orchids have fleshy roots, especially when there are wounds in the roots, and the application of high concentrations of fertilizers leads to fertilizer damage, which eventually leads to root rot. Therefore, when fertilizing, it is necessary to apply thin fertilizer frequently, and when using fermented organic fertilizer or long-acting fertilizer, do not get too close to the roots to avoid rotten roots.

When orchids are threatened by pests and diseases, they will cause root rot, so it is necessary to use drugs to kill pests and diseases in time to allow the roots to grow healthily. At the same time, maintain a ventilated environment, watering to be moist but not wet, dry but not dry, and give certain light conditions every day to promote root absorption and growth.

1. Change pots as soon as possible.

It is found that the orchid rotten roots, it is necessary to change the soil on the pot planting material, the planting material should pay attention to the quality and water absorption performance, to fire soil or dry soil, charcoal and other planting materials as well, but also in the root reed part of the appropriate cover of some coarse sand, the effect is better.

2. Control sunlight.

For a period of time after changing the pot, it should not be exposed to the scorching sun, and it should be placed in a place with shade and air circulation, but it should be noted that the wind should not be too strong to avoid being affected.

3. Pay attention to the method of changing potted plants.

In addition to ensuring that the potting soil is waterlogged, the planting material from the lower part of the reed head to the outside of the root should be dense, and the reed head should be planted appropriately deeper, which not only plays a protective role, but also prevents the reed head from shaking or floating off the soil surface. Rotten roots and shrunken and yellowing leaves should be cut off to reduce nutrient loss and store nutrients in the reed head to maintain root development.

4. Reasonable watering.

In the cultivation management, the water should be strictly regulated, and the potting soil should be semi-wet and dry, neither white and dry in the potting soil, but also not obviously too wet. In case of rain, you should move to a sheltered place and try to control the moisture of the potting soil to ensure its normal rooting.
