How to repot orchids, how to repot orchids

After digging out and patting off the soil, replant it with acidic and fertile soil [root pruning].

Spring after the sting before the vernal equinox.

Autumn after the white dew before the autumnal equinox.

This is the so-called principle of not missing the agricultural time.

The best time to divide the blue.

When repotting an orchid, you first need to remove the orchid from the old pot, turn the pot with your left hand, and then pat the pot with your right hand to loosen the root system of the orchid. Once the orchid is removed, the soil at the roots is cleaned and the rotten root system is pruned. When repotting, you can choose sandy loam soil with rich trace elements and loose soil as a new cultivation medium, and after the repotting is completed, you need to water it immediately.

How to change the pot and transplant the orchid.

When repotting an orchid, the first thing you need to do is remove the orchid from the pot. You can turn the pot with your left hand and pat the pot with your right hand to loosen the soil in the pot, and the orchid will naturally fall off from the pot, and then the orchid can be taken out for transplanting.

After the orchid is removed, the soil at the roots should be cleaned and the rotten roots should be pruned off, taking care not to touch the new roots. Avoid the death of the orchid's root system after it is damaged. After that, it is necessary to prune off the rotten and hollow bulbs, and pay attention to protecting the new shoots when pruning to avoid touching the bulbs.

When potting orchids, you should also pay attention to the choice of soil, which is suitable for growing in nutrient-rich and well-drained soil. When repotting orchids, you can choose sandy loam soil or yellow loam soil with rich trace elements and loose soil as the substrate for cultivation.

After the repotting is completed, it is necessary to water the entire soil once, and you can choose to water the mineral-rich river or lake water. Later, a compound fertilizer rich in phosphorus and potassium elements can be applied to speed up the growth rate of orchids. It can also provide about six hours of astigmatism every day, which makes the orchid grow more vigorously.

1. Flower pots: Orchids should be repotted and transplanted to choose pots of appropriate size and loose texture. 2. Soil:

Coconut shell blocks, moss, perlite, and fir bark were used as soil for transplanting orchids. 3. Transplant into pots: pour out the orchids, wash the roots with warm water, and replant them.

4. Water and fertilizer: After the orchid is repotted and transplanted, it should be watered every day and water-soluble fertilizer should be applied once a week.

1. Choose a flower pot

When changing pots and transplanting orchids, you need to choose a flower pot with a suitable size and loose texture, and there should be enough holes in the side wall of the pot to facilitate the air permeability and drainage of the potting soil, and the pot should not be too deep, otherwise it is easy to accumulate water.

2. Prepare soil

When transplanting orchids, it is not advisable to use ordinary soil, it is best to use loose nutrient soil, which can be mixed together with coconut shell blocks, moss, perlite, and fir bark to make a nutrient-rich and breathable soil.

3. Transplant into pots

Shake the orchid pot from side to side to separate the plant from the pot wall, pour out the orchid slowly, cut off the excessively long, rotten roots, then rinse the roots of the plant with warm water, and finally replant it in new potting soil.

4. Replenish water and fertilizer

For the first three days after repotting and transplanting orchids, you should insist on watering the plants every day to promote the recovery of orchid growth, but to avoid water accumulation in the pot, you only need to let the soil be slightly wet, and apply water-soluble fertilizer to the plants once a week.

Orchids can be dried for at least a week after depotting, if the location of ventilation, lighting, temperature, air humidity and other conditions are suitable, not only can be placed for a long time, but also can absorb nutrients and moisture from the air and grow, there is a month of adaptation after moving the pot, commonly known as serving pots, the old grass leaves are not twisted, flipped, the leaves are vibrant, and the new seedlings and leaves are new and green that is.

How to tell if you are alive.

Because it takes at least a month for an orchid to survive after repotting, it is necessary to observe it 20 days after repotting. First of all, observe whether the old leaves are flipped or wilted, and secondly, whether new young leaves have grown in the center of the leaves. If there are no abnormalities and young leaves are growing, it means that the orchid has fully lived.

In order to ensure that the survival rate of orchids can be increased after repotting, the roots can be pruned to a certain extent before potting, and all the old and diseased roots should be cut off. After completion, the roots should be sterilized, and the potting soil should be sterilized before it can be used.

Precautions for repotting orchids: pruning the root system, soil conditions, controlling watering.

1. Prune the root system: When the orchid is moved to the pot, it needs to be placed in a dry and ventilated place to dry the soil, and then gently knead the soil with your hands to make the root system of the orchid out of the pot, and you need to try to avoid hurting the root system of the orchid, so as not to die of the plant, and then use sterilized scissors to cut off the necrotic root system of the plant.

2. Soil conditions: orchids are suitable for growing in loose and fertile humus soil, and can use humus, garden soil, and vermiculite at 3:2:

The ratio of 5 is mixed and prepared, the soil of this preparation is not only rich in humus, but also has excellent air permeability and drainage ability, and can also be mixed with some nitrogen, phosphorus and potassium fertilizers in the soil to improve the fertility of the soil.

3. Control watering: Orchids will be in a long period of time after moving pots, in this period, if watering too frequently, it will lead to water rot of the root system, you need to spray water on the leaves of orchids with only a long-necked watering can every morning and evening to maintain the humidity of the plant, and the orchid can not be watered for about 20 days after the potting.

History of Botany

Orchids have been cultivated in China for more than 2,000 years. It is reported that as early as the end of the Spring and Autumn Period, King Goujian of Yue had planted orchids in the mountains of Shaoxing, Zhejiang. After the Wei and Jin dynasties, orchids have been used to decorate courtyards.

In ancient times, people mainly collected wild orchids, and as for the artificial cultivation of orchids, they began in the court.

After the Wei and Jin dynasties, orchids were cultivated in the court and expanded to the private gardens of the scholar class, and were used to decorate the garden and beautify the environment, as described in Cao Zhi's poem "Autumn Orchids Are Long Slopes". It was not until the Tang Dynasty that the cultivation of orchid was developed to the cultivation of general gardens and flower farmers, such as the great poet Li Bai of the Tang Dynasty wrote poems such as "The fragrance of the orchid is far away, and the grass flows fragrant roots".

Orchids are generally repotted in spring and autumn in February April and September November to separate the orchids from the pots, and then the prepared new potting soil is exposed to the sun to disinfect, and the sick and old roots of the orchids are pruned with scissors. After that, the wound is sterilized and dried, planted in suitable potting soil, watered, and placed in a ventilated and bright place to maintain, so that it can slowly adapt to the environment.

Generally, the orchid repotting work is carried out in spring and autumn, mainly in February and April or September and November, when the climate is cooler, and the growth rate of orchids is relatively fast, and the pot can be used for growth faster.

Before the orchid is repotted, it needs to be separated from the original pot, and when depotting, it is necessary to pay attention to loosen the soil above the pot, and then detach it from the pot as a whole, so as not to damage the root system of the orchid.

The new pot of orchid repotting should choose a clay pot or porcelain pot of the right size with the body size of the plant, and also choose a slightly acidic soil prepared with humus, coarse sand and sawdust in a ratio of 1:1:2, and put it in the sun to disinfect before use.

In how to change the pot of orchids, it is also necessary to pay attention to pruning the root system of the depotted orchid, clean up the soil above, cut off the diseased roots, stump roots and old roots with scissors, and then apply potassium permanganate solution for sterilization to avoid wound infection.

The sterilized soil is placed in a new pot, and the wound-dried orchids are planted in the soil, gently compacting around their roots. Water the soil by watering the pot, and place the pot in a ventilated and bright place to maintain.
