Can flowers survive the winter safely at low temperatures of 4 to 5 degrees?

This mainly depends on the variety of plants, some flowers will be more frost-tolerant, and some flowers will not be able to grow if the temperature is lower than ten degrees. So will the flowers be able to survive the winter safely at such temperatures? Of course, we also need to pay attention to our maintenance methods.

At first glance, the subject knows that he lives in the southern region, and if he can still keep it above zero in winter, it is actually very good for plants. At this time, we need to let the plants receive more sunlight so that they can photosynthesize, and secondly, it is not to the point of freezing, so it is definitely safe to survive the winter. ‍‍

If the subject has planted a plant that is not hardy, then it is better to move it indoors at this time. Don't add too much water at this time, because the varieties of plants will definitely be dormant in winter, and if you water too much, the absorption will be slow, and it is easy for the roots to soak in water for a long time, and the growth will not be good. If it is a plant such as plum or autumn chrysanthemum, it is still okay for such a temperature, and it is completely possible to spend a peaceful winter.

Therefore, as long as we master the correct maintenance methods, even in winter, we can still maintain the plants well and safely through the winter. ‍‍

Orchids can survive the winter, but pay attention to a few points, orchids suffer from frost damage or late frost damage, but also easy to form leaf tips dry or discolored, therefore, in winter temperature below zero degree area, before winter, to move the orchid to indoor ventilation and sunlight for maintenance. When moving outdoors in spring, we should pay attention to avoid the harm of late frost, traditional experience: "spring is not windy (spring should not be moved too early to the outdoors to avoid strong winds), summer is not day" (summer should be properly shaded, to prevent scorching sun exposure), autumn is not dry (autumn should be watered frequently to prevent drought), winter is not wet (winter potting soil can not be too wet, to prevent freezing and root rot), which is good for preventing orchid leaves. ‍‍

Orchid wintering, we are talking about spring orchid and orchid here, other varieties are not discussed here. Most of the orchid-producing areas have four distinct seasons, and the temperature of snow in winter is normal below zero, and orchids are not frozen and extinct in the mountains, so orchids are not afraid of cold. The subject is talking about 4---5 degrees, which is still a long distance from freezing, and this temperature is not at all the pressure of wintering for Chunlan and Huilan.

Therefore, it can be placed outdoors for the winter. ‍‍

Do not water, at this temperature peanuts will definitely be safe for the winter.

China is a vast country, the temperature difference between the four seasons is large, the time of the spider plant to move into the house in winter can not be generalized, the time to enter the house should be decided according to the local climate change, I think if it is a spring orchid, we can choose to enter the house the day before the weather forecast freezes tomorrow, some people enter the room when the temperature is lower than 10 degrees, I think this is not conducive to the development of flower buds, the need to enter the room in advance will lead to the reduction of flower buds in the autumn of the following year, or even not, as long as the temperature is not lower than 0, the spring orchid should be in 10 to 0 This temperature can also make the orchid's tissues more full and healthy. ‍‍

In the north orchid wintering can be placed in a warm room, or in a general room such as a plastic shed, but the minimum temperature must ensure that the orchid is not lower than i to prevent frostbite, if it is below zero, it is harmful to any orchid in any case, and in any case it must not freeze the orchid. When the weather is too cold, heat it with an electric heater. ‍‍

1. Flowers suitable for wintering in cold rooms.

Potted camellias, rhododendrons, palm bamboos, smiling flowers, vermilion red, etc., in the Yangtze River basin, as long as they are slightly protected at low temperatures, they can safely overwinter in a dormant state. After entering the shed, pay attention to ventilation and cooling on sunny days, and do not break the dormancy. Of course, if the purpose is to promote flowers, it is a different matter.

Melon leaf chrysanthemum, primrose, pampa flower, cyclamen, calla lily, etc., the temperature during the day is kept at 15 -20, the temperature in the shed is too high should be ventilated, covered at night with insulation, the temperature is too low and should be warmed, keep it at about 5, not less than 0.

2. Flowers suitable for wintering in greenhouses.

Cactus, pineapples, arrowroot, variegated wood, Brazilian iron, fortune tree, dragon's blood tree, tropical orchid and other high-temperature flowers. First, the greenhouse is covered with insulation material to prevent heat loss at night, which is extremely effective at night on sunny days. Second, a simple shed is set in the greenhouse, that is, a double-layer shed, the spacing between the two layers of plastic film is best about 10 cm, the air thermal conductivity in the middle is small, the effect of thermal insulation is better, and the temperature in the shed is more stable.

Third, warming, heating with electricity or boilers, the energy consumption is larger, the cost is higher, can be combined with the first two measures, in the particularly low temperature and rain and snow days for a short period of time. In the clear daytime, the temperature in the shed should be above 25, and the flowers should be ventilated to keep dormant for winter.

In addition, the air humidity in the greenhouse is high, and special attention should be paid to the prevention and control of fungal diseases such as black spot and powdery mildew. Dormant and overwintering flowers, to stop fertilization, control watering, maintain a semi-arid state, in order to prevent rotten roots and dead seedlings, flowers growing in the shed should also be moderately controlled watering, see dry and wet, frequent ventilation, maintain strong growth.

Flowers suitable for low temperature environments are:

Pulsatilla, Daisy, Dahlia, Upside-down Admiralty, Hyacinth, Melon Leaf Chrysanthemum, Nasturtium, Purse Peony, Chrysanthemum, Gentleman's Orchid, Blue Pot Flower, Lily of the Valley, American Caryophyllus, Tricolor, Daffodil, Four Seasons Primrose, Geranium, Tulip, Spanish Warbler's Tail, Cyclamen, Caryophyllus, Violet, Bamboo, Yueji, Dutch Dwarf Double Root Sunflower, Melaleuca Multiflora, Melaleuca Multiflora, Melaleuca Flora, Melaleuca Flora, Goldenrod, Goldenrod, Safflower Silver Birch, Silver Acacia, Australian Goldenrod, Red Chowler, Chinan Peach, Heteroptera sylvestris, Danny Acacia, fine-leaved wild peony, etc.
