How to raise orchids so that they don t rot their roots, and how to grow orchids? How can I keep the

In fact, orchids like a moist environment, but the fleshy roots of orchids are afraid of waterlogging, so it is easy to rot roots if they are too wet or rainy, leading to many diseases. So how can you prevent orchid root rot?

Orchids (details).

In winter, orchids are in the dormant or slow growth stage, and the potting soil should be dry; Spring and early summer are important periods for the growth of orchid peanut roots, and the potting soil should be moist. However, long-term overhumidity is also easy to cause root rot, causing leaves to wither and even die. Because of excessive water, the soil is waterlogged and the air permeability is poor, resulting in insufficient oxygen, hindering the respiration of the roots, and causing the roots to turn black and rot. During the rainy season or rainstorm, the orchid must avoid its harm, because of the long rain and humidity, black spots are most likely to occur on the new leaves, and the stamens often have "rotten clothes", which affects flowering and ornamentation.

However, if the potting soil is too dry, it is easy to dry up the pseudobulb or other tissues to lose water and affect the metabolism, which will also lead to weak tissues and poor plant growth. In autumn, the potting soil should be wet, so as to facilitate the removal of leaves and flowers in the coming year. Therefore, orchid growers should know the trick of "not getting wet in winter and not dry in autumn".

The above illustrates the different water requirements of orchids at different times, so the amount of watering should be strictly controlled according to the requirements. At the same time, improper fertilization of orchids is also easy to cause root rot, such as too much fertilizer, too concentrated or liquid fertilizer into the leaf sheath, will have an adverse effect on orchid flowers. When fertilizing, the amount of fertilizer should also be increased or decreased according to the amount of watering, so that it can grow in harmony.

With plastic foam blocks at the bottom, orchids are not easy to rot roots, have a high germination rate, white and long roots, and are easy to produce leaves. The fly in the ointment of plastic foam blocks is the lack of organic fertilizers, which can be improved by fertilization.

When raising orchids, in order not to let the orchids rot their roots, they can be planted in soil with good air permeability. When mixing the soil, add particles such as vermiculite, ceramsite, maifan stone and other particles to the humus and peat. Control orchid watering, strictly control the amount of watering, keep the soil dry and wet, and loosen the soil and drain the water in time.

Pay attention to reasonable fertilization, avoid top dressing or raw fertilizer, and prevent burning and rotting roots. In summer, avoid direct sunlight and store in a cool place to prevent root rot at high temperatures.

When planting orchids, you must choose to configure air permeability and good soil, so as to reduce the possibility of rotten roots, and the roots of orchids are relatively thick. I am very afraid of water, so do not choose a very clayey soil, as this will cause water to accumulate in the soil and cause root rot. Also control the amount of watering, don't water the orchid too much at once, don't let the orchid be exposed to the sun, the sun exposure will increase the temperature of the roots and lead to root rot.

Proper fertilization is required, incorrect fertilization can lead to too much fertilizer and root rot.

When raising orchids, in order to make orchids not rot roots, they can be raised in soil with good air permeability, and particulate matter such as vermiculite, ceramsite, and maifan stone can be added to humus soil and peaty soil when mixing soil. Control the watering of orchids, strictly control the amount of watering, keep the soil dry and wet, and loosen the soil and drain the water in time when it is waterlogged. Pay attention to reasonable fertilization, avoid topdressing thick fertilizer or raw fertilizer, and prevent root burning.

In summer, avoid direct sunlight and keep it in a cool place to prevent root rot at high temperatures.

Orchids are depotted without rooting, and the rotten roots, dead and diseased roots are pruned off with sterilizing scissors, and disinfected with a multi-linge solution. The rooting powder is dissolved in water and prepared into a low-concentration rooting solution. The orchid is then soaked in rooting solution for half an hour.

After drying and planting in the soil, a new root system will grow after about a while.

1. Depotting and pruning

In order to promote the phenomenon of orchid peanut roots, first of all, it is depotted, and the roots are cleaned one by one, and the rotten roots, dead roots and diseased roots are pruned off with sterilizing scissors, and disinfected with Duoling fungus solution, and placed in a ventilated place to dry. Be careful not to injure the root system during depotting.

2. Apply rooting powder

To prepare a basin of water, dissolve the rooting powder in the water and mix it into a low-concentration rooting solution. Then soak the young orchid plants in the rooting solution for half an hour. Finally, it is removed and placed in a more ventilated environment to dry.

3. Preparation of potting soil

Because orchids like to grow in well-drained, fertile and loose, acidic soil containing humus, they can be mixed with six parts of garden soil, two parts of coarse sand, two parts of cinder, and two parts of decomposed organic fertilizer. Flower pots should have a certain degree of air permeability and water permeability, and can be used clay pots, clay pots, and purple sand pots.

Fourth, replant

Orchids are planted in sterilized soil and kept in place after covering. If the potting soil is relatively dry, you can water it appropriately to keep it slightly moist. In this way, after a period of time, new roots will grow, and maintenance and management measures such as light, fertilizer and water and temperature will be taken well.

1. To provide orchids with a better quality of water for watering, the best choice is rainwater, river water or well water in nature, but if you use tap water at home, you need to put it aside for more than a day before irrigation.

2. When maintaining orchids, do not use the original plastic pots for planting, because the plastic pots not only have poor air permeability but also contain some toxicity, so it needs to be replaced in time. You can choose a clay pot with good air permeability or a porcelain pot, a purple sand basin and so on.

3. Although orchids like water very much, the water in its pot should not be too much, and the humidity in its pot should always be kept at about 50% to 70%. If the rotten roots are caused by heavy water, the soil should be replaced in time, and the soil should be replaced with new soil and replanted.

4. Keep its growth temperature at about 20 degrees, and put it in a place with plenty of light for growth.

5. If it is caused by disease caused by rotten roots, it should be taken out of the pot in time, and the diseased roots should be pruned off, smeared with disinfectant and dried in a cool and dry place, and then replaced with new soil to plant.

Don't blame the water for raising orchid rotten roots, this misunderstanding is the culprit.
