How do orchids divide and repot? When is the best time to repot orchids?

1. Keep the potting soil moderately dry before depotting, which is conducive to the rapid and complete depotting of orchids, and the damage to the root system is also minimal.

2. After removing the soil on the root system, check whether the root system is rotten, if there is, use sterilized scissors to trim the root system, and then follow the root system of the plant, divide the orchid into two plants, try to reduce the wound of the root system, according to this principle, you can divide an orchid into multiple plants, to achieve the purpose of one pot into multiple pots.

3. After pruning, soak and disinfect with carbendazim solution for a while, and after drying the wound in a cool and ventilated place, you can directly divide the seedlings into pots!

4. Keep the potting soil slightly after potting, and then water normally after a few days, and after passing the seedling period, you can maintain it normally.

Clause. 1. Depotting.

When depotting, you can hit the potting soil with water to expose the roots of the orchid. Then gently rinse the soil attached to the orchid to see if there are empty roots, rotten roots, and intersecting and disordered roots, and repair it with scissors.

Take a look at the division when dividing, generally more than five seedlings can be divided, and the parts that are connected together can be directly cut with a knife when dividing.

Clause. Second, the soil.

The soil of orchids can be used with rotten pine bark, red jade soil, volcanic stone and other granular soil, which can be configured in a ratio of 5:3:2.

You can also use peanut shells, mixed with granular soil, or peat soil with granular soil. It can be matched with red brick particles, ceramsite volcanic stone, red jade clay, etc., as long as the soil is loose and breathable and does not accumulate water, the soil is slightly acidic.

To maintain the orchid pot, try to use a purple sand pot with good air permeability, which is more beautiful and atmospheric, and you can also use a clay pot. After planting, the potting soil can be covered with dried moss or ceramsite.

Clause. 3. Watering.

As long as the soil is well controlled, watering is easier. After the moss is dry, we remove the moss and look at the discoloration of the volcanic rock, which contains water and is darker. If it's shallow, it's a lack of water.

After the planting material is dry, we can water it once, and the soil we configure can absorb water, retain water, and the excess can flow out.

Clause. Fourth, the environment.

In the spring the weather is warm and the climate is humid. Orchids can be placed on the outdoor ventilated balcony, placed on the north balcony to diffuse light to maintain the best, the air on the pot to form up and down convection, orchid leaves and roots breathe smoothly, orchids will grow very vigorous.

Clause. 5. Fertilization.

If the planting material is well configured, the supply of orchid nutrients can be guaranteed for a long time. After slowing the seedling, you can apply some multi-element fertilizer to it, and you can put it with Aolu slow-release fertilizer in the potting soil. Apply potassium dihydrogen phosphate to orchids before flowering every 7 days.

Discontinue use when flowering. It can improve the disease resistance of orchids and make it prolong its flowering period.

It is recommended to choose the period between flowering and germination, and choose the appropriate pot according to the growth of the orchid. After that, the orchid needs to be removed from the old pot, pruned and then planted in a new pot, buried with fine soil, watered thoroughly after the repot, and then transferred to a warm location for maintenance.

It is recommended to repot orchids from the time they bloom to the time before germination. At this time, it is not easy to hurt the root system of the orchid. In addition, due to the different varieties of orchids, different orchids also have different tarets and repotting times.

Before the orchid is divided, it is necessary to choose the appropriate pot according to the growth of the orchid, and if it grows more vigorously, you can divide several more pots. Furthermore. The new pot needs to have good air permeability and not be too large, so that the orchid can grow better.

Once the new pot is ready, the old plants need to be removed from the previous potting soil and put in clean water to wash the soil from the root system.

When dividing the plants, you need to prepare a sterilized cut and cut the orchid vertically from the base of the orchid rhizome. When pruning, it is necessary to prune along the root system of the plant, and the action should be gently kneaded, so as not to hurt its roots. After pruning, carbendazim solution should be applied to the wound for sterilization and disinfection.

After pruning, you can fill the new pot with breathable new soil, and then fill it with some breathable material to plant the orchid in the new pot and bury it with fine soil so that its root system is completely on the soil. After that, the soil is compacted, watered thoroughly and then transferred to a warm location for curing.

It is best to repot and divide the orchids within half a month after they have fallen, because if you divide the plants before flowering, you may have fewer or no flowers. If the leaf buds are divided at the time of tillering, there is a risk of injuring the leaf buds.

After flowering, the genes for reproduction begin to dormant. Dividing the plant after flowering will also help the leaf buds to differentiate better. When the orchid blooms, it grows and develops in a diapause stage, after flowering, the reproductive genes will begin to dormant and begin to enter the growth stage again.

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.

After the pot is full, it is advisable to divide the pot once every 2 3 years, from March to early April (autumn orchid), or from October to mid-November (summer orchid, spring orchid). When dividing pots, the potting soil should be drier. If it is wet mud, it is inconvenient to operate, and it is easy to break and hurt the roots.

After the mother plant is turned out, gently remove the mud blocks, prune the dead roots and residual leaves according to the natural plant, and pay attention not to touch the leaf buds and fleshy roots. Then wash the roots with clean water and put them in a shaded place;

When the root color is white and dry, it can be disassembled and potted. If the weather is getting wet, it must be exposed to the sun for about 10 minutes, which is conducive to the growth of orchids, and the place where the orchids are placed is very important, which directly affects the growth and development of orchids.

Orchids need to choose healthy orchid plants when dividing pots, and after dividing pots, you need to disinfect the cutting wounds of orchids, wait for the wounds to heal, you can plant orchids in the soil with rich organic matter content and loose soil, and at the same time need to water water into the soil to help the plants adapt to the environment.

1. Obtain plants

Orchids need to be harvested before they can be potted. First, you need to select a healthy ramets that need to be potted and strong, free from pests and diseases, and then you can observe the roots and remove the orchid ramets with a sharp blade. Pay attention to the maximum amount of rub when taking the ramets to ensure that the wound is minimized, so as not to affect the growth of orchids.

2. Select the soil

When planting orchids, you also need to choose the right soil. Orchids are suitable for growing in soils with rich organic matter content and loose soil, so it is best to use sandy loam soil with rich trace element content and loose soil when planting orchids. At the same time, it is necessary to loosen the soil regularly after planting to improve the air permeability of the soil.

3. Planting

Before planting orchids, you need to soak the roots of the orchid with carbendazim solution, take it out after five minutes, and put the orchid in a cool and ventilated environment, wait for the orchid wound to heal, you can plant the orchid in the soil prepared in advance, and then use an appropriate amount of fine soil to bury the orchid roots.

4. Later maintenance

In the later maintenance of orchids, it is necessary to provide an appropriate amount of water for the plants, soak all the soil, create a more humid growth environment for the orchids, and also provide suitable light for the orchids to maintain the normal growth of the plants, and also need to provide reasonable nutrients for the orchids, so that the plants can grow more vigorously.

Preparation: Prepare the soil with humus, vegetable garden soil and river sand, and apply sufficient amount of basal fertilizer to the soil. Ready to repot:

After removing the orchid, shake off the sticky soil of the root system, and inspect and prune the root system, paying attention to spraying carbendazim on the wound after pruning. Repotting: After the orchid is replanted, the soil is compacted and watered to moisturize.

1. Preliminary preparation

When repotting orchids, it is necessary to provide them with good air permeability, soft and fertile soil, which can be mixed with humus soil, vegetable garden soil, river sand, etc., and apply sufficient base fertilizer to the soil to ensure that the soil fertility is abundant, and pay attention to the soil to be disinfected before use.

2. Prepare to change the pot

Carefully remove the orchid from the old potting soil, gently shake off the soil where the root system adheres to it, check the growth of the root system of the plant, and cut off the old, rotten, and excessively long root system, leaving only the strong root system, and pay attention to apply carbendazim solution to the wound after pruning is completed.

3. Repotting

Place the pruned orchids in a cool and ventilated place to dry, and then replant them in the new potting soil, water them after covering the soil and keep the soil moist, avoid water accumulation, so that the root system is in close contact with the soil, which is conducive to the rapid recovery of orchid growth.
