What is the overwintering temperature of potted lemons in Beijing? When do you enter the winter? What needs to be done before wintering?

Potted lemons have poor cold tolerance, so they need to be kept indoors for winter maintenance, and the temperature should be controlled above 5 degrees. It is also necessary to provide appropriate moisture for plants during indoor maintenance to keep the soil moist, and at the same time, we should pay attention to regular ventilation and keep the ambient air circulating.

Indoor wintering

Potted lemons do not have strong cold resistance. In winter maintenance, potted lemons need to be stored indoors, and the temperature should be controlled above 5 degrees. It is best to put lemons on sunny windows or indoor balconies, which can not only prevent frostbite of lemons, but also provide appropriate illumination for maintaining normal growth of plants.

Proper watering

Potted lemons need water during their growth, but indoor maintenance in winter needs to reduce the supply of lemonade, so as to avoid the death of lemonade. Generally, just pour a proper amount of water into the soil every other week, and at the same time, when the temperature is high, it can also be properly sprayed on lemon leaves.

Proper fertilization

Potted lemons can't be fertilized in deep winter maintenance, at this time, the growth of lemons is slow, and the fertilizer used can't be absorbed by plants, but in the first winter, lemons can provide plants with proper nutrients, at this time, plants can absorb more nutrients and store them in their bodies to maintain their own growth in winter.

ventilate regularly

The most important thing for potted lemons is to ventilate regularly. The growth environment of potted lemons is humid and hot. If it is not ventilated for a long time, it will lead to the growth of bacteria on plants, so plants will be infected with diseases. Therefore, indoor maintenance needs regular ventilation, and ventilation is needed in the afternoon. At this time, there will be no frostbite plants when the temperature is high.

It is best to move the potted lemon tree indoors in winter, because the outdoor temperature is too low in winter, so as to avoid freezing injury outside, which will occur in different degrees in an environment below -2℃. Its optimal growth environment temperature is above 23℃, and the indoor temperature should be kept above 15℃ in winter to be safe for winter. It should also be placed in a sunny place and often open the window for air.

First, how to safely overwinter the lemon tree

Potted lemon trees can be moved indoors or inside the balcony after winter, which can prevent frost and snow from freezing directly. In case of frosty and snowy weather, the top crown of outdoor lemon trees can be covered with plastic film, which can keep warm and prevent freezing. If the lemon trees planted in the ground are relatively tall, the trunk and main branches can be painted white with sulfur mixture, which can not only prevent freezing, but also have the functions of sterilization and pest control.
