Will the northern azalea be freeze dried if it is placed on a windowsill?

The difficulty of potted azaleas in the north is greater than that in the south, and some flower friends ask whether the northern azaleas will freeze-dry on the windowsill, and if there is no heating, they will freeze to death in most cases, so it is not recommended for flower friends to do this!

For potted azaleas, its cold hardiness is not good, in the south of the Yangtze River can naturally spend the winter, but not in the north, azaleas do not have very high requirements for light, so it is recommended that northern flower friends put azaleas in a warmer place, and when the weather is warm at noon, they can be placed on the windowsill to bask in the sun.

Of course, there is another situation, that is, there is a heated room in the north, because the room is too dry, the temperature is also high, so the window sill is not very cold, in this case it can be placed on the window sill, but it should be noted that the window sill is best not to penetrate the cold air, if there is wind, you can put a plastic bag!

For the problem of low air humidity and too dry in the northern winter, let's take a look at the solution of a flower friend:

Rhododendron is bright in color, large in flowering, long in flowering period and does not have a high demand for light, it is very suitable for indoor raising, but in the north it is recognized by flower friends as difficult to raise flowers, often bought back can only see the flowers once, and they die for unknown reasons. Some flower friends said that it was because the air humidity in the north was too low, which was not suitable for raising rhododendrons; There are also flower friends who say that the water in the north is alkaline, and the rhododendron likes sour, which is not suitable for raising rhododendrons.

In the Northeast, the winter is short and there is little light, and there are few plants that bloom in winter, so when I visited the flower market this spring, I couldn't resist buying a pot of rhododendrons. At that time, I noticed that the seller raised the rhododendron in the whole basin. There is a flower friend who raises rhododendrons with a thread suction method, and he raises them very well.

After reading it, my eyes lit up, and I felt that her method was very similar to the seller's cultivation method. However, because the flower friend simply mentioned the offline sucking, and other aspects were not introduced, so I started my attempt under the premise of sucking.

After nearly a year of careful maintenance, it has reflowered perfectly, so I send out my maintenance experience, hoping to help flower friends who have a dry climate like me and like rhododendrons.

Let's start with the line. The shoelaces I use are the most ordinary black shoelaces, and then the basin, the clay pot I use, I take into account that I am afraid that the thread will absorb too much water, and the clay pot has good air permeability, which can be more or less breathable.

The size of the pot, I take it out separately, because I think this is very important, I picked the pot is only a little larger than the original soil mass, that is, the size that can be put into the soil mass is the best, if the pot is deeper than the original soil mass, the bottom is padded ceramsite, the soil mass is best flush with the basin surface, and the space around the pot is filled with deer swamp soil, because the size of the pot is very close to the soil mass, and it does not use much deer swamp soil. I use deer swamp soil for a reason, I used to see that flower friends there like to use deer swamp soil to raise rhododendrons, it is said that because the deer swamp soil is acidic, considering that the chance of using granular soil and water to rot roots will be smaller, I used deer swamp caulking.

In the northern region, if you put it on the windowsill, it will not freeze dry, but will freeze to death, so you should put the azaleas in a warm place, and you can put them on the windowsill to bask in the sun when there is sun at noon.

There will be a certain chance of freeze-drying, the cold tolerance of azaleas is not particularly good, if there is heating in the home, there is direct sunlight on the windowsill, then you can put it on the windowsill, but avoid leaving the window open for a long time to blow the wind.

It will not freeze-dry on the windowsill, but it is recommended to increase the humidity of the air at ordinary times.

Rhododendron is not afraid of freezing in the wild, and it still does not die in the winter in the alpine area, but the potted rhododendron has poor cold resistance, and can usually be moved indoors in winter to prevent freezing, and can be moved out of the outdoor planting when the temperature rises in spring, and the current weather has little impact when it is placed outdoors.

Rhododendron does not freeze to death in winter.

Rhododendron is not afraid of freezing in winter, rhododendron is a plant that is very resistant to cold, and it will not freeze to death when placed outdoors in the cold winter, but the overly cold winter environment will delay the flowering time of rhododendron in spring, and rhododendron can withstand at least -8 low temperatures in winter.

Introduction to azaleas

Rhododendron belongs to the rhododendron family, rhododendron genus plants, there are many other names, the distribution range is relatively wide, so the names of each region are different, but also called mountain pomegranate, Yingshan red, mountain heel, Zhaoshan red, Tang rhododendron, etc.

Rhododendron is a deciduous shrub with a height of about 2-5 meters, with more slender branches and some rough hairs densely distributed. The leaves are leathery, about centimeters long, slightly curled at the edges, and have small fine teeth on them.

It blooms in April-May, the corolla is broadly funnel-shaped, and the color is red, sometimes bright red, sometimes dark red or rose. It can bear fruit and can produce oval-shaped capsules.

Rhododendron prefers to grow in acidic soils and does not grow well in alkaline soils. Like a cool climate environment, afraid of extreme heat in summer, can not withstand the cold climate in winter, the temperature suitable for growth is about 12-25 degrees Celsius, so you need to take measures to keep warm in winter. It is suitable for growing under astigmatism, if the light is too strong, the leaves will be burned, and if the light is not enough, it will grow poorly.

Rhodocarpus and cuckoos are not afraid of the cold, and they will not freeze to death if they are left outside in the cold winter.

However, too low temperatures will delay its flowering time in spring. In winter, the plants should be properly ventilated during the winter rhododendrons, and the amount of fertilizer should be stopped and the amount of water given to the plants should be reduced.

You can spray water on the branches and leaves once a day at noon, and water the plants when the soil is dry to keep the potting soil wet or moist.

The rhododendrons can tolerate a minimum of -8 cold weather in winter, but if the temperature is any lower, the plants will really freeze to death.

Rhododendron can be kept outdoors in winter.

Whether or not the azaleas can be left outside in winter depends mainly on the temperature outside.

If the outside temperature is lower than 3, it may be frozen, so if the temperature is higher than 6 in winter, it can be placed outside, and if the temperature is low in winter, it is recommended to move it indoors for maintenance.

Rhododendron can survive the winter in the north, although it likes to be cold, but after changing the pot for the winter, you should pay attention to the heat preservation of the plant, you can build a small shed in a sunny and ventilated place, cover with plastic film to help the plant survive the winter safely. <>

Rhododendron is afraid of cold. Rhododendron is not hardy, it is a thermophilic flower, the temperature in winter should not be too low, generally speaking, the minimum should not be less than 6. But there are many varieties of azaleas, and some are frost-tolerant.

For example, deciduous rhododendrons can tolerate low temperatures from minus 20 degrees to minus 30 degrees, evergreen rhododendrons can tolerate low temperatures from minus 10 degrees to minus 15 degrees, and ordinary rhododendrons can tolerate low temperatures of minus 3 degrees.

Rhododendron is a highly ornamental flower, in the winter breeding, to move to a warm room, must keep the indoor light sufficient, to ensure that the sun can reach the rhododendron, so that it can be safe to overwinter. In addition, the amount of watering should be appropriately reduced in winter to avoid the soil being frozen, and there is dust on the leaves, which can be sprinkled and cleaned.

Winter maintenance method of rhododendron potato bridge1. Keep warm: Put the azaleas into indoor breeding in winter and keep the temperature above 6 degrees.

2. Water control: After the potting soil is dry, water is poured to keep the soil dry.

3. Pruning and shaping: prune the dead branches and rotten leaves and dense branches of azaleas to reduce nutrient consumption.

4. Fertilization: Stop fertilizing in winter, and add a diluted compound fertilizer or soybean cake fertilizer before spring.

Because of the cold, the leaves are likely to have died or yellowed, and we need to knock them off, but we can't repair the branches too early, because even though the leaves are falling, the green branches can still photosynthesize. Generally, if the injury is relatively small, the leaves are disposed of, and if the injury is relatively large, the branches are disposed of.

In addition, there is another reason why pruning should not be done too early. If the branch is pruned, it still needs a lot of nutrients to heal the wound, so the loss of nutrients will also be a lot, and it has no effect on the recovery of frost damage, so the general pruning time is before the buds begin to germinate, and it cannot be shaped at one time.

In the beginning, we only cut a small part, cut off the dead ones, and wait until the buds grow out, and then cut off the ones that can't grow buds, and when we cut them, we have to smooth the opening, and the frostbite area should also be pruned and smoothed, and then we have to detoxify it. We should also note that there will be a lot of dense spring shoots growing after pruning, and we need to treat them in time to make them evenly distributed.

We should be careful not to let the temperature in the room be too low, it is better to be above three degrees, and not to let it close to the stove, because this place is very dry, and this flower prefers places with high humidity, in addition, we should put it in a place with strong light, because the light is very weak in winter, if the outside temperature is above three degrees, it is better to let it go to the sun, because it is likely to fall leaves due to the lack of sunlight for a long time.

When there is dust, we can spray it with water to wash it off, so that the cotyledons are not easy to fall. If it's in the south, and occasionally it's sub-freezing, you can still leave it outside for the winter.

If you get frostbite, we need to apply more nitrogen fertilizer, less each time, a little more often, start with a thin one, and then thicken it. In addition to this, it is necessary to top dress its leaves, and also to supplement it with trace elements. After thawing, loosen the soil to raise the temperature of the soil.

Rhododendron can not be placed outside in winter, because azaleas are not cold-tolerant, leaving it outdoors will cause the plant to be frostbitten, breeding azaleas in winter, you need to keep it in a warm place indoors, and to control the frequency of watering, it is best to water after the soil is dry, and you need to stop fertilizing to avoid fertilizer damage to azaleas.

In winter, the rhododendron can not be put outside, because it is a non-cold-tolerant plant, the temperature in winter is relatively low, at this time if it is placed outside, it is easy to produce frost damage, so in winter, we had better move the azalea to a warm place indoors to maintain, so that it can safely overwinter.

When maintaining azaleas in winter, you also need to control watering, because the temperature is low at this time, and the water evaporates slowly, when we water it, we need to carry out it according to the dry and humid soil, and it is best to master the principle of dry and thorough watering, and must not water too much, otherwise the root system of the rhododendron is easy to rot.

In winter, the rhododendron is in the dormant period, at this time it grows slowly, and the demand for nutrients is not high, so we need to stop fertilizing, and any fertilizer should not be applied, otherwise the plant can not absorb it will lead to excess nutrients in the soil, which will cause fertilizer damage to the rhododendron plants.

If you want the rhododendron to overwinter safely, you also need to place it in a well-lit place, so that it has enough light, if you want it to bloom, then we need to do a good job of temperature control measures, if the temperature is controlled by about 20, its flowers can open quickly.
