How to raise orchids in winter?

Improve cold resistance. Michelia has poor cold resistance. Can a change of environment improve its cold resistance? The answer is: yes. Stop fertilizing, especially nitrogen fertilizer, after autumn. Of course, some phosphorus and potassium fertilizers can be properly applied, and at the same time, watering should be controlled to keep the basin soil dry and promote the growth of branches and leaves to be more lush. This can effectively increase the resistance of plants, and it is not so easy to get down when the cold wave comes.

If the temperature drops below 0℃ and is properly heated, the growth of Milan will be broken and the leaves will be frostbitten. Generally, plants will be moved indoors early, and the weather conditions will be closely observed and countermeasures will be taken. Put the flowerpot in a sunny place indoors, not in the vent, so as to avoid the cold wind blowing to the plants. The indoor temperature should not fluctuate too much throughout the winter, so as not to affect the dormancy of plants. Generally controlled at 10~ 12℃. If the room temperature exceeds 15℃, plants will sprout new buds and consume nutrients.

After winter, it doesn't mean that winter in Milan is over. Don't be outdoors too early in early spring, so as not to be attacked by cold wind. After leaving the house, dried bamboo shoots are easy to appear, which will affect flowering. After moving outdoors, the temperature is still low, so the whole plant can be covered with plastic film or cold-proof materials, but the time should not be too long, so as not to affect the photosynthesis of plants and accumulate nutrients.

Proper watering in winter makes Milan dormant or semi-dormant. It is not allowed to make the basin soil too dry or too wet, and it is not allowed to wait until the basin soil is dry before watering, and it is not allowed to water it. It is necessary to ensure the water balance in the soil of the basin. In addition, in order to prevent the leaves from being covered by dust, which hinders photosynthesis and causes the leaves to turn yellow and fall off, spray water close to room temperature every 10 day to clean the leaves, and be careful not to spray too much water.

Don't leave the room too early. The first part of the article mentioned that the winter in Milan is very long, and the cold wave in early spring is also winter for Milan. So when the climate is unstable in spring, don't rush to move the flowerpot outdoors. Before leaving the room, you can open the window around noon to ventilate, so that the plants can adapt to the outside environment in advance and move outside in a few days. If you suddenly encounter a strong wind and cold wave, you need to move indoors in time.
