Why is the root rotten? 1. Water and fertilizer management is improper

Phalaenopsis sometimes improper watering or pot soil matrix bad, there will be rotten root phenomenon. If too much watering, long-term ponding in the basin, it will lead to the occurrence of rotten roots;

Too much fertilizer, resulting in excessive accumulation of nutrients in the pot can not be absorbed, fertilizer damage will also cause root rot. Therefore, to avoid rotten roots, we must first do a good job of water and fertilizer management.

2. Water accumulation in flower pots

Keep the soil moist, but do not accumulate water, which is the main cause of rotten roots. To pay attention to observation, watering, a long time infiltration does not go down, indicating that pot soil use time is long, density increases, should quickly change the soil, so as not to rot roots.

How to prevent Phalaenopsis root rot

First of all, when selecting culture soil, the selection of substrate should be strict, and it is necessary to ensure that the soil is loose and breathable. The recommended use is peat mixed with perlite or peat mixed with pine needles, only the use of moss is also possible. Organic fertilizer is best used as base fertilizer.

Secondly, while ensuring that the basin soil is moist, it cannot cause ponding, which is the biggest reason for the rotten roots of plants. After watering, the pot soil should be carefully observed. If it is found that the water poured is difficult to seep, it means that the density of the pot soil increases with the increase of use time. It is necessary to change the soil in time to prevent rotten roots.

First of all, the pot soil should be dug out from the flowerpot and scattered, the roots of the plant should be washed with clean water, and then all the rotten roots should be cut off. The intact parts should be preserved as much as possible, and the residual roots may also be saved.

Put the cut and remaining residual roots into the potassium permanganate solution with a concentration of 2% for about 10 minutes and then dry them. Then carefully smear them with plant ash at the cut, and then the plants can be re-potted.

The basin soil must be disinfected. The simple method is to irrigate the basin soil with boiling water and reuse it after cooling. When putting on the pot again, pat the rhizome, pour water thoroughly and put it in shade, cover it with a thin film, cultivate it at about 20℃, and new roots can grow after about 20 days.

How to control the rotten roots of Phalaenopsis

Phalaenopsis is a genus of orchid, native to subtropical rainforest areas, epiphytic orchids. Sometimes improper watering or pot soil matrix bad, there will be rotten root phenomenon, gradually die.

II. Control methods

1. Can knock basin soil get loose, with clean water will root rinse clean, cut off rotten root part, and try to preserve intact local. Soak the cut and residual roots in potassium permanganate 2‰ solution for 10 minutes, dry them, smear the cut with plant ash, and then put them in the pot again. Basin soil must be disinfected, available boiling water will be poured through the basin soil, cool and then use. When re-potting, press the roots, pour water, put them in the shade and cover them with a thin film. The temperature should be maintained at about 20℃. New roots can grow in about 20 days.

For rotten roots to rootless seedlings, cut off the black rotten stems and plant them on the edge of the strong seedlings pot. After about 4 months, two new leaves can grow. It is estimated that the roots have grown, but the leaves are slightly thin (similar to the newly purchased seedlings in the market).

2. Phalaenopsis is best used in large pots, not plastic pots. In summer, it should be placed in the shade and watered at least twice, otherwise, the orchid leaves are easy to dehydrate. Spring, autumn, winter I use full sunlight, watering once a day, according to the surface conditions, determine the amount of water (to the surface wet and not subject to ponding).

The above is how to do Phalaenopsis rotten roots, Phalaenopsis rotten roots control method article, Phalaenopsis was born in tropical rain forest areas, nature likes warm fear of cold. The optimum temperature for growth is 15~20℃, and it will stop growing below 10℃ in winter, and it is easy to die below 5℃. Phalaenopsis can protect itself from stress in low humidity due to its physiological structure, but in too humid environment, high temperature and high humidity are often accompanied by diseases. The optimum range of relative humidity is 60%~80%RH.

Phalaenopsis root rot after the rescue method, Phalaenopsis root rot how to deal with

5, re-basin

After we have done enough preparation, we can pot the plants. To pot, compact the soil above the rhizomes of the plants, then water them once and place them in the shade. Finally, cover the pot surface with a layer of film, on the one hand, it can keep moisture, on the other hand, it can control the temperature, let the plant grow in the environment of about 20℃, about half a month later, you can see new roots, indicating that the plant has been successfully rescued.

How to prevent root rot in Phalaenopsis 1.

Potted Phalaenopsis on the soil requirements are relatively high, in the selection of soil requirements loose, breathable, strong water permeability.

2. In terms of watering

To basin soil often keep wet can, but avoid basin ponding, because said before, basin long-term ponding easy to lead to rotten roots. Pay attention to the change of pot soil when watering. If a small amount of water cannot penetrate, it means that the pot soil is too tight or there is accumulated water in the pot. You can use toothpick insertion to determine whether there is water, if there is water, then you need to stop watering, drain from the bottom or change some dry soil; if there is no water, it should be the reason why the pot soil is too tight, then we need to turn the pot to change the soil to avoid causing rotten roots.
