It's mid-October, and the temperature is getting lower and lower day by day. Guangzhou, which has a pleasant climate, also began to cool down overnight, with some wearing short-sleeved shirts, some wearing jackets, and some wearing down jackets... Plants, like humans, have the ability to perceive temperature changes.
For cold-resistant plants, they will restore their ability to grow when they feel the temperature drop. For plants that are afraid of cold, in order to protect their lives, they will enter a state of "retreatment". If there is no maintenance management combined with "warm", the plant will have the problem of being frozen and withered . Which plants are "not cold-tolerant"? Here are 3 common ones.
Jasmine
Jasmine is an evergreen shrub. Although the leaves are green all year round, the plants are afraid of the cold and grow at an appropriate temperature between 20 and 35 degrees Celsius. When the temperature is below 15 degrees Celsius, the plant will enter a dormant state independently and will no longer grow and bloom. The jasmine flowers in the dormant state are more "sexy" than usual. If you wait for improper maintenance, you will easily have problems such as yellow leaves, rotten roots, withering, etc.
has cooled down. How to maintain jasmine flowers to avoid the problem of freezing damage? First, when the temperature of is lower than 20 degrees Celsius, move it to the room for heating and maintenance. Secondly, jasmine flowers love light and need to be placed in a sunny place to maintain. Plants that are exposed to sufficient sunlight can also improve their cold resistance. Furthermore, start controlling the water, extend the interval between watering, and see that the soil is dry, water it thoroughly. When watering, it is best to choose noon with a small temperature difference. Finally, cannot be fertilized. Fertilization requires waiting until spring is in full bloom.
Tiger tail orchid
Tiger tail orchid
Tiger tail orchid is an perennial evergreen herb. Although it has a relatively long lifespan, Tiger-tailed orchid is very afraid of cold. The growth temperature is between 20 and 30 degrees Celsius. When it is below 20 degrees Celsius, the plant will automatically enter a dormant state and will be damaged by frost below 10 degrees Celsius. Dormancy does not show signs of growth, but it also requires light, moisture, etc.
has cooled down, and the leaves of the tiger tail orchid have become weak. What should I do? Since the tiger tail orchid is afraid of cold, when the temperature drops below 20 degrees Celsius, move it to a warm indoor location for maintenance. For the needs of light, although is half-shade orchid, after cooling, it can shine in sufficient sunlight, which can improve the ability to resist cold. For moisture demand, Tiger tail orchid to drought. After the temperature drops, keeping it dry will help the plant dormant. For nutritional needs, no fertilization maintenance cannot be carried out after cooling down.
Copper Citrus
Copper Citrus 0 The scientific name of Copper Citrus is: "Wild Sky Coriander", which is a perennial whole plant of water or wet-growing herb. Although the plant is evergreen all year round, Cottonwood is very afraid of cold and has a suitable temperature between 20 and 28 degrees Celsius. When the temperature is below 15 degrees Celsius, the plant enters a dormant state; when the temperature is below 5 degrees Celsius, the plant is easily frost damage.
has cooled down, and the leaves of the coin grass turn yellow? . Because of the temperature, Cotton Grass likes a warm spring climate. When the temperature drops below 5 degrees Celsius, the roots are prone to freezing, which causes yellowing of leaves. Ventilation problems, if you move to the room after cooling down, the air will not circulate, which will easily cause the leaves to turn yellow.
After cooling down, the "cold-resistant" flowers will automatically enter a dormant state in order to protect their own lives. At this time, how to maintain and manage is very important. If the maintenance is improper, it is very easy to cause freezing damage, which is manifested as yellowing leaves, rotting roots and other problems. Jasmine, tiger-tail orchids, coin grass, and other "cold-fearing" flowers and plants all need to be maintained and managed warmly.
