How do potted white orchids survive the winter outdoors at minus 10 degrees Celsius?

Potted white orchids can freeze to death even indoors at temperatures of minus 10.

The root system of the white orchid is fleshy, it is not hardy and prefers a warm environment. Especially in winter, it should be moved indoors in time and kept warm. Give it a temperature of more than 12 during the day and no less than 6 at night, otherwise it will get frostbitten.

White orchids are not cold-resistant, except for South China, other regions should be maintained in the winter room, when the temperature drops to 10 degrees after the frost, it is necessary to move the white orchid into the indoor sunny place, stop watering in the room, keep the potting soil slightly moist, do not over-humidify.

The minimum room temperature should be kept above 5 degrees, the most suitable temperature is about 10 degrees, and the temperature drops to about 5 degrees Celsius need to be protected by a transparent plastic bag.

If the temperature drops sharply below 0 degrees Celsius, the plants are damaged by frost, do not rush to a warm place, and should pour warm water of about 30 degrees in the pot to avoid physiological drought and wilting.

It is advisable to go out of the room in Qingming to Guyu, and after leaving the house in spring, you should cut off the old leaves, leaving only a few pieces at the top to promote new branches. Partial leaf plucking is also done after each flowering to reduce nutrient loss.

1. Keep warm: If you want white orchids to spend the winter outdoors, you need to use straw rope to wrap around the trunk of the plant to keep warm. 2. Pruning:

Cut off the dense and long branches of the white orchid. 3. Fertilization: Apply a hot fertilizer to the white orchid before winter to improve cold tolerance.

4. Painting: Paint the trunk of the white orchid with white paint to avoid cracking its bark.

1. Warm measures

White orchids have poor cold tolerance and are suitable for growing in a warm environment, when raising white orchids outdoors in winter, they need to be kept warm, they can be wrapped around the trunk of the plant with straw rope or straw mats, and the ground should be covered with a layer of straw to avoid frostbite of the white orchid.

2. Pruning

If you want the white orchid to survive the winter outdoors, you need to prepare a sharp and sterilized scissors to cut the branches and leaves that are too dense to improve the light transmission between the white orchids, and cut the branches that are too long to avoid the loss of excess nutrients.

3. Fertilization management

When raising white orchids outdoors in winter, it is necessary to apply hot fertilizer to the plants in mid to late October every year, and you can choose well-rotted cake fertilizer or manure to improve the cold tolerance of white orchids, and when fertilizing, you need to dig a ditch around the white orchids, and then bury the fertilizer in it.

4. Paint with white paint

If you want white orchids to spend the winter outdoors safely, you need to paint white paint or quicklime powder on the trunk of the plant to avoid the white orchid from cracking the bark due to the large temperature difference between day and night, and the white paint can prevent pests from burrowing into the trunk of the white orchid for winter, which is conducive to the vigorous growth of the plant.

White orchids survive the winter safely.

White orchid is not frost resistant, can not spend the winter outdoors, white orchid cold tolerance is not good, want to let it survive the winter, it is necessary to move it to the indoor after entering the winter, and keep the room temperature at about 5-10, if the temperature is too low, it will be frostbitten, or even frozen to death, in addition to the following two aspects:

1. Stop fertilizing.

Fertilization should be suspended in the half month before the beginning of winter, white orchids do not absorb nutrients in winter, and if they are fertilized regularly, fertilizer damage will occur.

2. Control watering.

In winter, the usual amount of watering should not be too much, the soil is not dry, there is no need to water, too much watering will rot the roots, if the room is more stuffy, but also open more windows.

White orchids are hardy.

White orchids are not very hardy, usually after entering the "autumn equinox" the temperature begins to drop, at this time to move the white orchid into the indoor maintenance, if not take timely measures to keep warm, the plant will be frostbitten.

White orchids are afraid of cold in winter.

White orchids are very afraid of cold in winter, so they need to be moved indoors for maintenance in winter, and the temperature should be controlled above five degrees and below ten degrees to avoid frostbite and death of white orchids.

White orchids freeze to death in winter.

White orchids will freeze to death in winter, if the temperature is lower than 5 degrees Celsius, they will have frostbite, and if the temperature is at zero degrees, they may freeze to death.

White orchids spend the winter in the north.

White orchids can survive the winter in the north, white orchids are also planted outdoors in the northern region, and the temperature in the northern region is very low in winter, so when raising white orchids, you should take cold-proof measures, do not let it be lower than 6, otherwise it will be frozen and grow poorly.

White orchids can not survive the winter outdoors in the north, because the temperature outside the north is low, and the cold tolerance of white orchids is poor, and they will be frostbitten in an environment where the temperature is lower than 0 degrees.

White orchids can not survive the winter outdoors in the north, because the cold tolerance of white orchids is poor, it is suitable for growing in a warm environment, and it will be frostbitten when the ambient temperature is lower than 0 degrees.

If you want the white orchid to survive the winter in the north, you should move the plant to a warm room from October to November every year, and adjust the indoor temperature to more than 10 degrees to maintain the normal growth of the white orchid, and open the window when the temperature is high to ventilate the white orchid.

When breeding white orchids in the northern winter, it is necessary to apply a hot fertilizer to the plants before winter, and you can choose well-rotted organic fertilizer or nitrogen, phosphorus and potassium compound fertilizer to promote the flower bud differentiation of white orchids, and spray potassium dihydrogen phosphate on the flowers of white orchids to increase the number of flowers.

White orchids will enter the semi-dormant period in winter, the demand for water is not high, in the northern winter breeding white orchids, you need to control the frequency of watering, you can wait for the soil surface to dry out before watering, keep the soil slightly moist, so as not to cause white orchids to rot roots.

The tips for outdoor wintering of white orchids are as follows:

1. Paint with white paint.

White orchids have poor cold tolerance, and when cultivating white orchids outdoors in winter, they need to use sulfur powder, quicklime and water to mix to make a whitening agent, and then apply it to the trunk of the plant to avoid the bark of the white orchid from cracking due to the excessive temperature difference between day and night, and the whitening agent can prevent pests from burrowing into the bark of the white orchid.

2. Watering method.

If you want the white orchid to survive the winter outdoors, you should choose to water the plant once from late October to mid-November every year to avoid frostbite on its roots, and apply a hot fertilizer for the white orchid, you can choose well-rotted organic fertilizer to improve the cold tolerance of the plant.

3. Warm measures.

When raising white orchids outdoors in winter, you need to take warm measures for the plants, you can use straw ropes or straw mats to wrap around the trunk of the white orchids to keep them warm and insulated, and cover the land with a layer of soil or straw leaves to raise the ground temperature and avoid frostbite of the white orchids.

4. Pruning treatment.

If you want white orchids to survive the winter safely outdoors, you should prune them before winter, you can prepare a pair of sharp scissors that have been disinfected, cut the branches that grow too long to avoid the loss of excess nutrients, and cut the branches and leaves of the white orchids that grow too densely to improve the light transmission between the plants.

Growth habits and environment of white orchids

Magnolia is more sensitive to temperature and blooms earlier the further south it goes. It blooms in April in Henan, March in Shanghai, and February in Kunming. In Hangzhou, flowers generally begin in mid-March, enter the full flowering period in late March, and wither in early April, with a flowering period of 10-20 days.

The flowering time depends on the temperature of the year, with the earliest flowers starting in late February and the later ones arriving in late March. The fruit begins to ripen in early September, and the seeds begin to fall off in late September.

Magnolia grows in forests at an altitude of 500-1000 meters, loves sunlight and is slightly shade-tolerant. It has a certain cold tolerance, can safely overwinter under -20 conditions, and can overwinter in the open field in the leeward and sunny areas of North China. Prefers fertile, moderately moistened and well-drained mildly acidic soils, but can also grow on weakly alkaline soils.
