How to raise orchids in winter

How to raise orchids in winter has a very important impact on the growth of orchids in the coming year, we can not generalize orchids, according to different varieties, choose different management methods.

In general, the orchid should be moved indoors for the winter, and the orchid should be moved into a sunny place indoors (such as a southern closed balcony). The winter temperature of the orchid should be between 5 ℃ and 15 ℃. If the room temperature is too low, it can not play the role of cold protection and warmth, and the temperature is too high, which will also affect the dormancy of the orchid.

What you need to pay attention to is that cold orchid and ink orchid should make the room temperature a little higher, but not more than 15 ℃. If the room temperature is too high, the flower stem grows slowly and the flower bud develops poorly, which is easy to make the formed flower bud shrink and die.

For the hardy orchids, a low temperature period of about 0 ℃ in 3 to 4 weeks is needed to help them complete vernalization. Only after vernalization can the orchids blossom. Therefore, the overwintering room temperature of Cymbidium should be controlled between 3 ℃ and 8 ℃.

How to raise orchids in winter-- watering

As the saying goes, "you can't get dry in summer and autumn, and don't get wet in winter and spring." this is the orchid cultivation experience summed up by our predecessors. Orchids are mostly dormant in winter, when less water is needed, and the basin soil is slightly moist and can survive the winter safely. If the basin soil is really dry, spray it with the same or similar water as the room temperature around noon in sunny and warm weather, so that the basin soil is slightly wet and do not flood, so as to prevent the basin soil from freezing or rotting the roots too wet. It is best to water with rain and snow water, not with tap water just released. If there is no rain and snow water, when you need tap water, you need to dry the tap water for a day or two before it can be used to water orchids. When watering, it should be poured from the edge of the basin, so that it gradually flows into the flower root, until the flower root is wet. Do not water the leaves and the center of the leaves.

How to raise orchids in winter-- controlling fertilizer and increasing light

Orchids generally do not need to be fertilized during hibernation. In general, when orchids change soil and pots every year or two, the changed soil already contains sufficient nutrients and can not be fertilized at all in winter. But Chunlan, cold orchid in the growing period, can spray a small amount of phosphorus and potassium fertilizer on the leaf surface. In addition, indoors, orchids can be given more light, such as lack of light, can be supplemented by lighting. If orchids have enough light in winter, it is beneficial to the growth and blooming of orchids in the following year. At the same time, it can also improve the cold resistance of orchids overwintering.

How to raise orchids in winter-- ventilation and ventilation

Orchids like to be warm and need air circulation, especially in the north, there is indoor heating, do not put orchids near the heating, at the same time, you should open the doors and windows for ventilation around noon in sunny weather, and you can also put the pot end to the outdoor shelter to see the sun, so that the orchid plants can absorb fresh air. The orchid on the closed balcony should also open the window door to make the air circulate. When the temperature drops, you should immediately close the doors and windows and put the pot end into the room to avoid freezing damage to the orchid plant.

Prevention of diseases and insect pests

Such as orchids overwintering indoors or on a closed balcony, when the temperature and humidity are slightly higher, once diseases and insect pests are found, they should be sprayed in time. Protective spraying should also be carried out at ordinary times, such as spraying basin soil, orchid plants and the environment around the basin with Bordeaux liquid, so as to prevent or reduce the occurrence of diseases and insect pests in the following year.
