How to remedy the rotting Root of Phalaenopsis

Every Spring Festival, Phalaenopsis will grow slender pedicels from the axils of the leaves, and then slowly bloom like butterflies, adding a lot of Spring Festival atmosphere to the festival, deeply loved by people and known as the "queen of orchids". The butterfly orchid is graceful and flies like a butterfly, hence its name, implying nobility and elegance. A Phalaenopsis usually grows two flower cores. When the flowers bloom, the petals are like crowded butterflies, bright and conspicuous, like a string of butterflies, very good-looking.

As a kind of ornamental potted flower, Phalaenopsis has beautiful shape, delicate and colorful flowers. But what if rotten roots are found during maintenance? The following editor talks about the treatment and prevention of the rotten roots of potted Phalaenopsis.

1. Why did Phalaenopsis rot

The direct reason for the rotting root of potted Phalaenopsis is the improper management of water and fertilizer. If too much watering, long-term accumulation of water in the basin, it will lead to rotten roots; if too much fertilizer, resulting in excessive accumulation of nutrients in the basin can not be absorbed, fertilizer damage will also cause rotten roots. Therefore, in order to avoid rotting roots, we must first do a good job in water and fertilizer management.

2. What about the rotten roots of Phalaenopsis?

1) remove the soil from the basin

When we find that the roots of Phalaenopsis planted in our home are rotten, we should first take the plant from the pot, clean up the soil attached to the plant roots, and then clean the plant roots.

2) pruning rotten roots

Then use sterilized scissors to cut off all the rotten roots and try to keep the intact parts, which may save the surviving roots.

3) Root disinfection

The residual roots will leave some wounds after pruning, which need to be disinfected so as not to infect the bacteria and induce rotting roots again. Soak the roots in potassium permanganate solution for a quarter of an hour and then set them aside to dry, then apply a layer of plant ash on the wound and you can put it back on the pot.

4) soil disinfection

We also need to disinfect the soil before putting it on the pot. You can use boiling water to irrigate the soil, then dry it, and then use it after cooling.

5) re-potting

After the preparatory work is done, we can pot the plant. When potting, the soil above the rhizome of the plant needs to be compacted, then watered once and placed in a cool place. Finally, covering the basin with a thin film, on the one hand, it can keep moisture, on the other hand, it can control the temperature, so that the plant can grow in an environment of about 20 ℃. New roots can be seen after about half a month, indicating that the plant has been successfully rescued.

3. How to prevent Phalaenopsis from rotting root

1) allocation of soil

Potted Phalaenopsis has high requirements for soil, and the selection of soil requires looseness, air permeability and strong water permeability. It is recommended to use peat + perlite or peat with pine needles. If there is moss, moss can be used alone as culture soil. Then apply some organic base fertilizer to the basin soil.

2) in terms of watering, the basin soil can always be kept moist, but avoid stagnant water in the basin, because as mentioned earlier, long-term stagnant water in the basin can easily lead to rotting roots. Watering should pay attention to observe the changes of the basin soil, if a small amount of water can not penetrate down, indicating that the basin soil is too tight or there is stagnant water in the basin. You can use a toothpick to determine whether there is stagnant water. If there is stagnant water, you need to stop watering, drain water from the bottom or change some dry soil. If there is no stagnant water, it should be the reason why the basin soil is too tight. At this time, we need to turn the basin and change the soil to avoid rotting roots.
