Are freshly potted orchids suitable for the sun in winter?

Are freshly potted orchids suitable for the sun in winter? One by one speak with facts, use practical experience to take you to raise the flowers at home, and play with you flowers.

In winter, the newly potted orchid seedlings can be completely basked in the sun indoors through the glass window, and at noon when the weather is fine and the outdoor temperature is not lower than 10 degrees, you can also move the orchids that have just been potted to the outside to bask in the sun, and at the same time you can accept good ventilation, which is very beneficial to the potting of orchid seedlings. While allowing orchid seedlings to receive proper light, we should also pay attention to other maintenance work.

First, the humidity of the planting material. When planting orchids in winter, if it is a relatively dry planting material before potting, we can use a watering can or sprayer to spray the planting material to a humidity of about 30%.

If the humidity of the planting material is particularly large, and even there is water seepage, such a high humidity planting material, do not plant orchids directly in winter, and spread them in a well-ventilated sun to dry until the water content is 30-40% before planting orchids.

Because the temperature in winter is relatively low, the growth activity of orchid seedlings is relatively low, and the potting time of orchid seedlings will be prolonged, so it is not suitable for too much humidity of planting materials in the pot, which will reduce the probability of water damage to the root system of the plant. Do not water the orchid seedlings after potting and planting, and you can water them again after 5-7 days. After that, until the temperature warms up, the humidity of the planting material in the pot should not be too high.

Second, spray nutrient solution in a timely manner. The orchid seedlings transplanted in winter will be potted slowly due to the slow potting, and the more tender seedlings will completely rely on the nutrients in the old seedlings to sustain their lives.

In this way, the old seedlings will be prone to yellow leaves, and it will often be seen after ten days to half a month. In order to alleviate the phenomenon of weeding of old seedlings, the leaves of orchid seedlings can be appropriately sprayed with an appropriate amount of thin nutrient solution while allowing the plants to receive light.

Potassium dihydrogen phosphate is the best, and the spraying time can be sprayed for the first time ten days after the potting, with an interval of one week. The dilution concentration of potassium dihydrogen phosphate solution is 1:1000-1200 times, only the back of the leaf, the foliar spray, can not be watered the roots.

At the same time, you should also be careful not to spray the nutrient solution into the center of the leaf, you can use a piece of toilet paper to roll it into a column and gently stuff it into the center of the leaf to prevent the nutrient solution from flowing into the center of the leaf. In this way, adding some thin foliar fertilizer can not only prevent the old seedlings from retiring, but also effectively shorten the potting time of orchid seedlings.

No direct sun exposure. Although the winter sunlight is relatively mild, but because the absorption capacity of the root system after the orchid is potted is relatively poor, the plant is relatively "weak" and the growth is very poor, and it is not suitable for all aspects of the new environment, and it is still in the stage of serving the pot and slowing the seedlings, will reduce the success rate of repotting, is not conducive to plant potting, and it is difficult for orchids to safely pass the slow seedling stage.

Basking in the sun is a must, if you don't bask in the sun all the time, not only will it be difficult to survive, but even the buds on the orchid plant will disappear.

If it is too cold in winter, it is not recommended to bask in the sun outside, after all, the sun is very scarce in winter, if the sun is good in winter and the temperature is high, you can bask in the sun outside, and if the temperature is low, stay indoors.

Freshly potted orchids, bai

In principle, it should be placed in astigmatism du for 2-4 weeks to let it.

DAO roots and leaves have an internal recovery process, and it is best to wait for it to be potted and then bask in the sun!

If it is just planted to let it receive relatively strong light, at this time its roots can not normally transmit nutrients and water to the leaves, as soon as it receives strong light, then the leaf will be damaged, and the leaf will be damaged, then its ornamental value can be greatly reduced!

Although the orchid belongs to the semi-shade of the plant, but in its growth process, the light must be inseparable, the orchid with more sufficient light, its leaves will be in that oily green state, the gloss is very good, it will look more ornamental, and if we give it insufficient light, then its leaves will grow very thin, the gloss will be very poor, and the beauty will be much worse!

Therefore, we raise orchids and give it a hard dry in winter, because the light is weak in winter, the sunshine time is short, and the light itself is not enough, so it is definitely not good not to give it more sun! In other seasons, if it is raised outdoors, then put it under the tree, or next to the root of the wall, if it is raised indoors, then put it on the balcony, or by the window, which can not only add a certain amount of light, but also prevent the leaves from sunburning!

Orchids can be sun-soaking for a week after they are potted. In fact, orchids are shaded mountain plants, and they should not be exposed to too much sun, as long as the light is good, they can grow normally without sunlight.

Orchids should not be exposed to direct sunlight in winter. Orchids prefer a semi-shady environment and avoid direct sunlight, especially black orchids. When maintaining orchids, shade them in spring, summer and autumn, and in winter, they can be placed in a brightly lit and astigmatized place.

Orchids are half-shade and half-yang plants, and it is beneficial to spend more time in the sun in winter. Just put it on the windowsill on the indoor side, not outdoors. When the temperature is high at noon, open the window appropriately for ventilation.

Although orchids love coolness, they rarely bloom if they are kept in a hidden place all year round. Orchid artists have long discovered that the leaves of the Yin Orchid of the Mountain are long and the flowers are sparse, and the Yang Orchid of the Mountain is short and has many flowers. Therefore, when cultivating orchids, we must pay attention to the problem of light.

In spring and summer, orchids are best shaded by reed curtains or placed in windows with ventilation facing east and south. The orchid under the curtain should be repotted once every half month, so that the orchid receives light on all sides, which is conducive to the balanced growth of the plant.

When autumn is cool, the potted orchid should be removed from the shade and let it bask in the sun for half a day in the morning, but be careful not to dry out in autumn. In cold weather, it is placed indoors under the south window for wintering, but it does not have to be too warm, and it is best to cover it with a plastic film cover to maintain the proper humidity of the leaves. As for the prevention and control of pests and diseases, such as brown rust and white silk disease, use 0.5% stone sulfur mixture**.

If there is an ant nest, you can soak the pot in water to drive it away.
