Winter conservation of Milan flowers: improving cold resistance

The cold resistance of Milan flower is poor, can changing the environment improve its cold resistance? The answer is: yes. After the beginning of autumn, it is necessary to stop fertilization, especially nitrogen fertilizer, of course, we can apply some phosphorus and potassium fertilizer appropriately, at the same time, we should control watering, keep the basin soil dry, and promote the growth of branches and leaves more luxuriantly. This can effectively increase the resistance of the plant, so that it is not so easy to get down when the cold wave comes.

Winter conservation of Milan flowers: appropriate warming

When the temperature drops below 0 ℃, Milan's growth will be broken and the leaves will be frostbitten. It is common to move the plants indoors early to closely observe the weather conditions and take measures to deal with them. Put the flowerpot in the sunny place indoors, not in the vent, lest the cold wind blow to the plant. The indoor temperature should not fluctuate too much throughout winter, so as not to affect plant dormancy. Generally, if the temperature is controlled at 10-12 ℃, if the room temperature exceeds 15 ℃, the plant will germinate new buds and consume nutrients.

After winter does not mean that the winter in Milan is over, early spring do not move to the outdoors too early, so as not to be attacked by the cold wind and easy to appear dry tips, affecting flowering. After moving outside, the temperature is still low, the whole plant can be covered with plastic film, or covered with cold protection, but the time can not be too long, so as not to affect the photosynthesis of the plant and accumulate nutrients.

Winter conservation of Milan flowers: proper watering

In winter, Milan is in a dormant or semi-dormant state, so it can not make the basin soil too dry or too wet, nor can it wait until the basin soil is dry, nor can it be watered, so it is necessary to ensure the balance of water in the basin soil. In addition, in order to prevent the leaves from being covered with dust, hindering photosynthesis and causing the leaves to turn yellow and fall off, spray water similar to room temperature once every 10 days to clean the leaves and be careful not to spray too much water.

Winter conservation of Milan flowers: 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 weather is not stable in spring, don't rush to move the flowerpot outside. Before leaving the room, you can open the window around noon for ventilation, so that the plant can adapt to the environment outside the house in advance, and then move outside a few days later. If you suddenly encounter strong wind or cold wave, you need to move indoors in time.
