When is the best time to change the pot and divide the branches

During the spring equinox in March, the weather is getting warmer, and this month is the best time for orchid branches to be repotted.

Potted orchids are limited by pots, and their vigorous roots are staggered and unable to stretch, and they continue to arch towards the surface of the pot, which brings difficulties to watering and fertilizing. On the male side, there are too many plants in the pot, which is impermeable to the wind, and is easy to be harmed by diseases and insects, which also brings difficulties to the future branching. For general varieties, divide and repot in two or three years; Precious variety.

Three or four years of dividing and repotting. Generally speaking, the time of dividing is determined according to the density of the plants in the pot, the characteristics of the pot, and the situation of diseases and pests.

When to divide the plant and change the pot, the famous orchid breeders of the past generations have their own opinions:

The Song Dynasty's "Jinzhang Orchid Spectrum" records that orchid branches should be after the "cold dew" and before the "beginning of winter" (early October to mid-November). Take its "when all things return to the roots, and its leaves are green, and the roots are old." ”

The Qing Dynasty's "Linghai Lanyan" recorded: after the "spring equinox" (March) of Molan; After the autumn orchid "Xiaohan", it is time for the old leaves to be unloaded, and new shoots will be born, and nothing goes wrong.

Deng Chengkang of Sichuan Province advocated in his book "Raising Orchids" that orchid branching should be carried out in spring and autumn. Summer-autumn flowering species, branching in spring; Species that bloom in spring, which are carried out in autumn or spring.

Shen Yuan from Jiangsu Province said in his book "Orchids": "During the year, spring, autumn and winter can be repotted, as long as the heat and freezing are avoided. The most appropriate period is after the 'spring equinox' and before the 'beginning of summer', or after the 'autumn equinox' and before the 'beginning of winter'. ”

Mr. Li Zonghou, an orchid expert in Taiwan, proposed three periods in his book "Collection of Famous Flowers": first, the period of the beginning of sprouts; 2. The period of new plant rooting; 3. After flowering.

Melan's best division in summer and winter every year, when the plant enters the dormant period due to the influence of temperature, the division will not affect the growth of the plant, and the healthy young plants need to be separated from the roots when dividing, and then planted in fertile and loose soil, and the roots can be buried with fine soil.

Melan dividing time.

1. Dividing time.

Melan ramets can be performed in both summer and winter of each year. Because the orchid will enter the dormant period in the hot weather in summer and the low temperature weather in the winter, and stop growing, the division of the orchid at this time will not affect the growth rate of the plant. When dividing the plants, it is also necessary to pay attention to the sunscreen and warmth of the Molan to avoid the death of the plants.

2. Soil ramification.

It is suitable for growing in the soil with rich trace element content and loose soil, and can be planted with humus soil with rich organic matter content and good drainage after dividing, and the soil can be renovated and dried before planting to eliminate pests and weeds in the soil.

3. Divide the plants.

When dividing the plants, you need to dig out the whole plant of Molan, clean the soil of its roots, and then select the young plants that grow stout and have not suffered from pests and diseases, separate them from the roots, soak them in potassium permanganate solution, wait for five minutes and then take out the young plants, and rinse them with water.

4. Transplanting and maintenance.

Once the ramets have been obtained, they can be transplanted. Directly plant the treated young plants in the soil, cover with fine soil, and after planting, you can pour non-polluted water into the soil to soak all the soil, so that the young plants can adapt to the environment as soon as possible, grow new roots for growth, and you can also appropriately apply some Trimegen Biduo to promote rooting.

Melan is suitable for potting time.

After the black orchid blooms, it can be planted in pots, if it does not bloom, it is better to change the pot before the Qingming Festival, and it is easy to survive during the potting period. Because at this time, not only the temperature is stable, but the new plant has enough time to adapt to the new potting soil.

The correct way to divide the pot in Molan.

When dividing the pot, he grabbed the base of the plant, turned the pot upside down, and then knocked the clods of soil at the roots, cleaned them up, and cut off the rotten and dry roots. It is then divided into 3-4 plants from the roots, and making sure that there is at least one sprout on each plant, and finally the plants are sterilized in 800x potassium permanganate.

Precautions for Moran ramets.

1. Do not water before dividing, and keep the potting soil dry. To judge whether a new plant has roots, you can judge whether the plant has new shoots.

3. Molan should avoid dividing during the flowering period, so as not to affect its flowering, and should be carried out after flowering.

When is the right time to water after the Melan is planted.

After changing the pot, you can water it immediately. Then put it in a cool, diffused place and it will soon be served in a basin.

What kind of soil is used to plant the Molan pot.

It is better to use the original humus soil for the substrate used in the subpot, which has the characteristics of good drainage performance and sufficient nutrients, and can meet the needs of plants after potting.

How long does it take for Molan to be potted in separate pots.

After Mo Lan changes the pot, put it in a cool place with scattered light, and it will soon be served in the pot.

When will the Mo Lan who has been divided into pots use fertilizer.

Fertilization in the spring is the best, and only when the orchid is trying to grow, it will absorb all the nutrients it has applied and turn it into motivation to grow hard. The best time to fertilize is after May in the spring, 10 to 15 days to fertilize once, although frequent, but do not apply heavy fertilizer water, light fertilizer water can be.

The time to divide the pots should be selected in the autumn when the climate is suitable. Because not only is the temperature stable at this time, but there is also a certain amount of time before the onset of winter, and the new plant has enough time to adapt to the new potting soil.

The substrate used for potting should use the humus soil under the forest where it originally grows, which has the characteristics of good drainage performance and sufficient nutrients, which can meet the needs of the plants after potting.

When dividing the pot, gently grasp the base of the plant, turn the pot upside down, gently tap the pot to separate the pot from the soil, and then knock off the soil clods on the root system, clean the root system, and cut off the rotten and dry root system on the root. After that, it is divided into 3-4 plants from the roots, and each new plant is guaranteed to have at least one new shoot. Finally, they are sterilized in 800 times potassium permanganate.

Prepare a few new pots, place a layer of broken tiles on the bottom of the pot, a layer of window screens, and then a layer of ceramsite and put in the plants. Then add humus to the base of the plant, and spread a layer of false mountain grass on the surface of the soil, so that the water will not splash when watering, which will affect the ornamental effect.

Its branches and leaves are tender and have more water, which is easy to attract insects. In addition to the usual precautions such as ventilation and frequent sun exposure, it is also necessary to observe its state frequently, and if you find insects in the branches and leaves, you can spray insecticides on the branches, and the dosage should refer to the instructions. If its potting soil is infected with pests, it needs to be repotted.

It can be repotted all year round, but it is especially suitable in spring and autumn. You should pay attention to if the plant has flower buds, do not toss back and forth, you can wait until the flowers are tired and change the pot.

At the same time as changing the pot, it is necessary to replace half or 2 3 of the old soil, and the soil around the roots should be retained, so as not to change the environment too much and affect the growth of the plant after changing the soil.

The soil is usually replaced by adding tree bark, peanut shells or bluestone to ordinary soil. Note: The new soil needs to be disinfected in the sun before use.

First, depot the plant and prune the roots if necessary. If the seedlings are not pruned, the soil at the roots should be preserved. Dry a little in the shade.

Add 2 to 3 new soil in the repot, then add the old soil, stirring a little.

Plant the treated plants, support the plants with one hand, fill the soil with the other, compact the soil, and do not hurt the orchid plants with too much force.

After changing the pot and soil, water thoroughly, put it in a cool and ventilated place, increase the air humidity, and it can be managed normally after 1 or 2 weeks.

Don't move it too often during the Molan basin period, just fix it in one position, the environment will change constantly and prolong the basin time.

Some of the orchids have bloomed in January, most of the flower arrows have also been drawn, you can move out and cut off the residual branches and leaves, pull out the weeds, tidy up the orchid leaves, put them in the spacious and bright hall, you can bask in the sun for an hour or two in the morning, do not be blown by the northwest wind and break the arrows to take off the buds, also avoid excessive watering, should not fertilize. 2 March is the peak flowering period of the orchid, the orchid garden hall is full of fragrance, it is not advisable to touch the buds and arrows with your hands when watching, so as not to be damaged. When the potting soil is too dry, it can be watered in moderation.

You can bask in the sun for an hour or two every morning to promote the release of aroma and increase fragrance. A few days after the flowers have bloomed to the top, they can be cut and inserted into the pot soil or placed in a vase. 3 After flowering in April, the growth of the orchid is the weakest, and the overly dense can be divided into pots.

At this time, most of the Molan is in the adjustment period, and it is not advisable to apply more fertilizer, as long as the appropriate amount of water conservancy relative humidity can be adjusted. 4 In May, the orchid began to bud (some of the orchids had already budded in September and November of the previous year, and they were quickly pumped at this time), so they should be properly protected. You can apply some thin fertilizer at the beginning, but do not apply it to the buds.

After that, top dressing is done every 10 days or so. 5 September, the temperature rises, it is the season of rapid growth of Molan, it is necessary to maintain a large relative humidity of the air and control pests and diseases. Mo Lan is most afraid of sun exposure, summer, autumn and winter are in the shade, especially at noon and afternoon, otherwise the leaves will be burned, and the appearance will be ugly.

The growth slows down in October, so you can consider repotting. Some Molan (Bangmo, Autumn Mo) bloom in November 10, so it is not suitable to change pots at this time. Some orchids begin to have flower buds emerging from the potting soil in October, so it is advisable to observe and protect them carefully.

The number of high flowers of the Molan arrow is large, and the gestation period of its flower arrow is also long. Some black orchids bloom from the end of autumn to the winter dormancy for a period of time, and then in the late winter and early spring to quickly grow arrows to bloom, this process is a bit like spring orchids, winter to be windproof, frost-proof, can not be placed outdoors. Mo Lan is afraid of cold, and it is best to put it in a greenhouse or a room with heating equipment in the provinces and regions north of Guangdong for winter.

In the autumn of October, pour the pot out to see the largest gap between the reeds of the **, commonly known as the road, separated from the **, you can divide several wounds, you can apply fungicide, or burn the wound with incense, and then the root is soft and can be re-potted.

After the autumn cools, take the orchid out of the pot, find 3 4 (can also be more) reed heads and divide them (note: you must bring a plate with one or more new shoots), simply disinfect with an alcohol lamp or 75% alcohol, cut off the stump and rotten roots, and then soak it in 75% chlorothalonil 800 1000 times solution for 15 30 minutes, or apply chlorothalonil or carbendazim or mancozeb to the wound after soaking. The surface is then dried until the roots are whitish and soft.

Finally, it can be planted.

It's too hot now, still in autumn or spring.

Its roots grow very quickly and quickly take up space in pots, which can be repotted once a year if possible. If the pot is a little large, you can also change the pot every two years. The benefits of changing pots are still more, which can ensure that the plants can have sufficient growth space, provide new potting soil to ensure new nutrients, and promote the normal growth of plants in the later stage.

1. When changing the pot, the soil can not be replaced, you can retain a part of the old soil, prepare the new soil, stir the soil evenly, and plant the whole plant into it. The new soil must conform to the growth habit, first of all, to ensure good permeability, river sand, bark, peanut shell, blue stone can be mixed with ordinary soil, so that the plant can grow normally in the later stage.

2. After the repotting is successful, you need to put the plants in a cool place first, and wait until the plants gradually adapt, you can contact the normal sunlight.
