Jasmine Winter Temperature and Care Methods
Today, the editor will introduce the knowledge about the winter temperature and care methods for jasmine, please see the detailed introduction below.
Jasmine Winter Temperature and Care Methods
One method for jasmine to survive the winter is to choose a warm care environment. If the indoor temperature is around ten to twenty degrees, it is relatively good for its growth. The second is to reduce watering, as excessive watering can damage the plant's roots, such as frostbite. The third is to prune appropriately to make the nutritional components more concentrated. It is often recommended to cut off the diseased branches and apply potassium permanganate solution to the cut ends to prevent the invasion of pathogens.
In winter, if some people do not take good care of their plants, it is difficult for the jasmine in their homes to survive. Some gardeners even find their jasmine plants die directly in the cold winter, leaving them with no choice but to throw them away, which makes the editor feel very sorry.
The Minimum Winter Temperature for Jasmine
Jasmine is not afraid of cold, but it cannot tolerate extreme or prolonged cold. Usually, jasmine can withstand low temperatures around 0℃, and can generally endure temperatures as low as -10℃. However, jasmine cannot stay in this temperature environment for a long time. If the temperature we care for is below -15℃, jasmine is easily frostbitten.
How to Help Jasmine Survive Winter
1. Move indoors
Since jasmine is fragile and cannot resist severe cold, when the temperature is low in winter, potted jasmine is moved indoors. If it is grown in soil, it is recommended to transfer it to a pot and cover the soil with a layer of pine needles to achieve good insulation.
2. Prune before winter
In winter, the roots of jasmine cannot absorb nutrients normally from the soil, so it is necessary to prune the branches of the plant appropriately to ensure that the plant has enough nutrition to survive the winter.
It is generally recommended to cut off the withered branches, diseased branches, and excessive branches, then cut off one-third of the healthy flower branches, and finally apply potassium permanganate solution to the cut ends to prevent the invasion of pathogens.
3. Reduce watering
In winter, the temperature is low, and the root activity of jasmine is not strong. Excessive watering can easily cause root rot, so whether to water depends on the dryness or moisture of the soil. How can you determine this?
Squeeze the potting soil with your hand. If the soil has stickiness, there is no need to water; if the soil is loose, you can water it moderately, but be careful not to sprinkle water directly on the leaves.
4. Lighting
In winter, jasmine should be placed in a well-lit area, such as near a window. Allow the plant to breathe normally by ensuring daily air circulation. If there is sunlight outside during the day, you can place the plant outdoors to bask and then move it back indoors afterwards.
What to Do If Jasmine Leaves Are Frostbitten
1. Slight frostbite
When the temperature is below 5℃ for 10 consecutive days, the tender buds start to frostbite and spread to the old leaves, causing yellowing and leaf fall, turning into a "deciduous plant." However, if the temperature rises, there are also some protective measures.
Slight frostbite does not threaten the growth of old branches or the life of jasmine. The frost-damaged jasmine plant will have slow germination the following year, weak buds, require a longer recovery period, produce fewer flowers, or may not bloom at all.
2. Severe frostbite
The temperature keeps fluctuating around -10 degrees, with 10 degrees during the day and 0 degrees at night. The flower buds will frostbite the old branches, and even if the temperature does not rise continuously, they will die.
If the old branches are frostbitten, as long as the base of the branches is close to the soil and the roots are not frostbitten, the jasmine will germinate when the temperature rises, but the flower buds will germinate about a month later than normal and there will be few buds, making it basically pointless to care for.
3. Directly frozen to death
The lowest tolerance temperature for flower buds is -5 degrees. If there is only -5 degrees at night, it can be determined that it has basically been frozen into severe frostbite, and it will be frozen to death after two consecutive days.
If there are multiple consecutive days with night temperatures at 5 degrees Celsius without human intervention, the jasmine can be pulled out. There is no possibility of recovery.
