When is the best time to divide orchid seedlings?

The best time for orchid raming is when the root system of orchids is the lowest vigorous, the so-called lowest root system vigor, in fact, it is very easy to understand, that is, when the root system is out of dormancy or just about to germinate, if the technology is not at home, we do not recommend the root system is very vigorous, that is, the vigorous stage of the branch.

So when is the orchid root system at its least vigorous? We can understand from the life activities of orchids, orchids are divided into dormant period, growth period, vigorous period, flowering period, and post-flowering recovery period, so the best time for orchid ramification is the dormant period and post-flowering recovery period.

Of course, in the orchid nursery, because the conditions are controllable, you can divide the plants at any time, and in the process of daily maintenance, the seedlings are strong and the ramets recover quickly, and it is not easy to retire, and the separating time is not much particular, and the seedlings are weak and do not recommend the growth period and flowering period.

In fact, most of these are hormone seedlings or tissue culture seedlings, and merchants will send rooting powder, which is very revealing.

Conclusion: It is recommended to wait for orchids to enter the dormant period before entering the dormant period, and to divide the plants after flowering, of course, if the seedlings are strong, they can be divided in a timely manner, but it is not recommended to divide the plants in the high temperature season, the high temperature season is easy to rot, generally in September and October, and if the seedlings are weak, according to the dormant period before and after flowering, the other time the branches are easy to cause serious weeding, and the weeding is easy to cause it to be difficult to repot, resulting in slow recovery and not easy to reflower.

For netizens said how to divide orchids, this is simple, the general steps of orchid division are to depot, remove mud, wash roots, divide plants, disinfection, dry roots, potting, slow seedling maintenance, normal maintenance, these steps I think there are several steps are very important, go to mud and wash roots, disinfect and dry roots, slow seedling maintenance.

The step of mud washing roots, generally two to three years to change the pot of orchids, or high-waisted potted orchids, the root system is lightly wound, pick out the root system with tweezers, rinse it with water, and for many years of orchids that have not been repotted, because the root system is seriously entangled, pay attention to separating the root system, do not cause too many root wounds, if the entanglement is serious, directly break it by hand, it is not recommended to use a knife.

After washing the roots, it is necessary to disinfect and dry the roots, the purpose of disinfection is to reduce the infection of wound germs, and the purpose of drying the roots is simply to say that there are two functions, one is to soften the root system, and it is not easy to break after potting, and the other is to let the root system get rid of part of the water, so that the root system can quickly carry out the function of water absorption.

For weak seedlings, we recommend that the wet soil pot, and then water the root water after the pot soil is dry, after the pot, water well, put it in a cool and ventilated place to slow down the seedling maintenance, do not expose to the sun, exposure to the sun is easy to dehydrate and wilt, and there is, after the potting weak orchid seedlings will appear appropriate weeding phenomenon, do not rush, normal maintenance, after the emergence of new shoots, these weeding leaves will automatically fall off.

Autumn when the sprouts are not unearthed. In the beginning, orchids were potted for a period of time, and the lack of nutrients was often supplemented by returning grass. After being cooked, they have to enter a rapid growth phase, which leads to a lack of nutrients.

Spring is the peak period for the germination of orchid roots, and pests and diseases are also active, which is not conducive to the healthy growth and rejuvenation of orchids in the later stage. It is prone to producing weak seedlings, but it is also prone to falling and dying. Therefore, it is ideal to equinox orchids in autumn.

Spring is the most suitable. Because spring is the season when everything grows, and the climate is also very suitable.

It is best to divide the seedlings in the spring. The temperature in this season is suitable, which is very suitable for growing after seedling. Proper supplementation of nitrogen and potassium fertilizers can promote the growth of plant roots.

1. Plants that are ready to be seeded should stop watering one week before, so that it is easier to depot and reduce damage to the root system. After depotting, you can see the intricate root system, and prune off the old, empty and diseased roots.

2. Prepare a sterilized cut or blade, find the node and cut it directly. Be careful not to hurt the root system with crystal heads, and make sure that there are three or five small seedlings in each bush after separation.

3. After that, soak the root system in the fungicide for a while, and put it in a ventilated place to dry the wound.

4. The wounds of each bush can be planted after drying, and the soil should not be too moist when planting. Don't be in a hurry to water after planting, water again about three days later, strengthen management in the later stage, and grow normally faster.

Orchid seedlings can be divided in spring and autumn, because at this time its growth is more vigorous, and it can adapt to the environment and begin to grow as soon as possible after seedling, while the climate temperature in summer and winter is high or low, which is not conducive to the growth and survival of seedlings.

1. When is the best time for orchids to divide their plants?

Orchids are suitable for dividing when the root system is less vigorous, that is, after flowering and before germination. At this time, the branch is not easy to hurt its root system. But because different varieties of orchids have different flowering times, different varieties of orchids also have different optimal dividing times.

Second, how to divide orchids.

1. Prepare a new pot, to divide the orchid, first prepare a new pot. If the plant grows vigorously, you can divide it into several pots and prepare 2-3 new pots. If the plant is not very vigorous, you can divide it into a few pots and prepare 1-2 new pots.

The new pot should have a certain degree of air permeability and not be too large, which is more conducive to the growth of the daughter plant.

2. Depotting of old plants: After preparing new pots, take out the old plants from the original pots and put them in clean water to wash the soil on the roots.

3. Divide the plant: Prepare a sterilized scissor and use it to cut the orchid plant vertically from the base of the rhizome of the orchid plant. When you see it, cut it along the root system of the plant so as not to hurt its roots.

It is also necessary to cut evenly to ensure that each subplant has the same amount of intact roots, stems and leaves. After cutting, the cut should be sterilized with a disinfectant.

Lu Zi 4, repotting: put soft and breathable new soil into the new pot, and then plant the seed plants into the new pot, put them in a warm place and slowly maintain, and wait for them to survive.

2. Due to the relatively developed root system of orchids, the development is limited by flower pots, which are coiled and staggered in it, and there is nowhere to stretch, so fertilization and watering are very unfavorable. Moreover, the pot is more crowded, the air permeability is poor, it is easy to be threatened by pests and diseases, and it is also difficult to divide the plants. Therefore, it is usually necessary to change the Qizi pot once every two or three years after planting, and if the variety is more valuable, it can be changed every three or four years.

However, the root system in the pot is not the same, the potting soil, diseases and pests are different, and the time of dividing will be different.

3. If we divide the plants before flowering, it may cause the plants to bloom less or not at all. If the leaf buds are divided at the time of tillering, there is a risk of injuring the leaf buds. Moreover, the varieties are different, the living environment is different, and the interference from the outside world is different, so it is impossible to find an accurate time to divide the plants without harming the plants.

4. When the orchid blooms, its growth and development are in a diapause stage, and after flowering, the reproductive genes will begin to dormant and begin to enter the growth stage. Therefore, it can be repotted within half a month after the flower falls, so that the flowering of the plant will not be affected, and the leaf buds of the plant will not be damaged. Dividing at this stage will also help the leaf buds to differentiate better.

In general, the best time for orchids to divide is after flowering.

1. What is good for dividing 1, the root growth rate of this kind of plant is relatively fast, so it is generally divided according to the root growth of the plant, and it is also divided according to whether the plant is infected with pests and diseases, so the dividing time of the plant is different because of the different varieties and growth habits.

2. The plant can not be divided before flowering, otherwise it will affect the flowering period of the plant, reduce the number of flowers or make the plant bloom later.

3. When the plant germinates, it can not be divided, if the leaf buds are damaged during the operation, it is not conducive to the growth of the plant.

4. The plant will enter the dormant period after flowering, which is the best time to divide the plant, which will not affect the flowering of the plant nor the growth of the plant, so many people choose to divide the plant after flowering.

2. Precautions 1, the root growth rate of this type of plant is relatively fast, so in order to better grow the plant, it can be repotted once in about two or three years.

2. The dividing time must not be selected before flowering, otherwise it will affect the flowering period of the plant, reduce the number of flowers or make the plant bloom later.

Orchids are most suitable for spring and autumn equinox pots.

It is best to divide orchid seedlings in the peak growth period of orchids, that is, spring or autumn, these two seasons are the stage of vigorous growth of orchids, which and the temperature of the time is between 15-25 degrees, neither cold nor hot, orchids grow fast, slow seedlings are fast, and the old plants can also send out new orchid seedlings after potting, which is particularly beneficial to the reproduction of orchids.

How to divide orchids into pots

1. Do not water the orchid within a week to ten days before potting, so that the potting soil is kept dry, so as to protect the root toughness and avoid damage to the roots when potting.

2. Take out the orchid plant, remove the soil, clean the roots of the orchid plant, and disinfect and dry the whole plant. After drying, in a relatively open place in the middle of the orchid plant, break it into two clusters, if the orchid has more branches and leaves, you can divide several more clusters, each cluster is not less than 3-5 seedlings.

3. Smear the wound of the orchid plant with sulfur powder or fungicide, and then place it in a cool place for about 7 days, without watering, and place it until the root cut surface of the orchid seedling heals.

4. After placing the seedling roots, you can plant, the seedling roots should be closely combined with the pot soil, put the plant in the center of the pot, so that the roots are evenly distributed, grasp the seedling roots with one hand, fill the culture soil with the other hand, water thoroughly after the pot, put it in a cool and humid place, and then properly control the amount of water until new shoots grow.
