Winter Care Methods for Household Potted Flowers

Winter is coming soon, and many netizens ask how to care for household potted flowers in winter and what care and management methods exist for household potted flowers. Here is a brief introduction: winter care for household potted flowers mainly focuses on the following aspects: increasing light, controlling fertilization, controlling watering, increasing humidity and preventing dust, and keeping warm and protecting against cold.

1. Increase light

In winter, sunshine duration is short and sunlight intensity is low, and indoor light conditions are poorer than outdoors. Therefore, when growing flowers in winter, attention should be paid to increasing light so that the flowers can grow vigorously. For flowers brought indoors after late autumn, they can be placed in different indoor positions according to their ecological habits. Usually, flowers that like strong light and high temperatures and those that bloom in winter and spring are placed on or near a south-facing windowsill in a spot with ample sunlight; flowers that like sunlight but can tolerate low temperatures, or that are already in a dormant state, can be placed in a spot with bright scattered light; other flowers that can tolerate relatively low temperatures and have already shed their leaves or do not have strict light requirements can be placed in a darker and cooler spot. It should be noted that the room should maintain air circulation, and windows should be opened around midday when the temperature is relatively high to ventilate and exchange air, so as to reduce the occurrence of pests and diseases. At the same time, attention should also be paid not to place potted flowers in drafty spots at windows, to prevent cold wind from directly blowing on them and causing freezing damage, and they should also not be placed directly on radiators or near coal stoves, to avoid scorching the leaves or scalding the roots due to excessively high temperatures.

2. Control water and fertilizer

In northern regions, because winter temperatures are low, after the beginning of winter many flowers successively enter dormancy or semi-dormancy. At this time, metabolic activity is extremely slow, and water and fertilizer requirements are very low. Therefore, except for species that bloom in autumn, winter, and early spring and most foliage plants, which should continue to be watered and fertilized appropriately according to their habits, general potted flowers should have their water and fertilizer supply strictly controlled. If the potting soil is not dry, do not water; if watered too much, it easily causes root rot and leaf drop. Fertilizing potted flowers in winter should also be reduced. For flowers in a dormant or semi-dormant state, fertilization should be stopped, otherwise root rot is very likely, and even the whole plant may die. Especially for potted flowers placed in rooms with low winter room temperature or without heating equipment, even more attention should be paid to reducing the frequency and amount of watering, so that the potting soil often remains appropriately dry, to avoid root rot or cold damage. In winter, watering should preferably be done around midday, not in the evening, to avoid the potting soil being too wet and the roots being harmed by the cold at night. Tap water used for watering flowers should be used only after more than one day of sun exposure. If the water temperature differs from room temperature by more than 10 degrees, it is very easy to damage the roots and cause leaf drop.

3. Increase humidity and prevent dust

Indoor air in the north is dry, which very easily causes dry leaf tips or flower and bud drop in flowers that like humid air. For this reason, during the wintering period, clean water close to room temperature should often be used to spray and wash the branches and leaves, so as to increase air humidity. When potted flowers are placed indoors for too long, a layer of dust often covers the leaves, and this is especially serious in rooms heated by coal fires. This not only affects photosynthesis in the flowers but also hinders their ornamental value. Therefore, they need to be cleaned in time. Small tweezers can be used to hold a small piece of foam plastic or sponge and dip it in a small amount of very dilute neutral laundry detergent solution to gently scrub the branches and leaves. Immediately after scrubbing, rinse away the remaining laundry detergent residue with clean water, and let them dry naturally. When increasing humidity and removing dust for potted flowers in winter, attention should be paid not to add too much water to the potting soil, causing the potting soil to become too wet and leading to root rot.

For foliage plants, take 1 part beer, add 2-5 times water, and use fine gauze to gently wipe the leaf surfaces, or use a small spray bottle to spray the front and back of the leaves, about once a month. This can make the leaves rich green and bright, and can also make the leaves thicker, thereby improving their ornamental value.

4. Keep warm and protect against cold

When growing flowers in winter in the north, moisture retention and cold protection are key measures. When the winter temperature is below 5 degrees, most warmth-loving flowers will suffer cold damage, showing adverse symptoms such as discoloration and necrosis; when the temperature drops to zero degrees, they will suffer freezing damage, leading to plant death. Therefore, cold protection measures must be taken. As long as the room temperature is kept above 15 degrees throughout the winter, and the flowers are placed in appropriate indoor spots according to the temperature and light requirements of each type of flower and carefully cared for, the flowers can be grown well. Simple heat-preservation equipment can also be made by oneself, so that the flowers can safely pass through the cold winter.
