Heat preservation

The lower the temperature of potted aloe in winter, the greater the harm to the growth of aloe. Therefore, if it is not too cold in winter or there are heating conditions indoors, you can directly move potted aloe into the room for overwintering; If the temperature cannot be guaranteed above 5 ℃, thermal insulation measures shall be taken. Rectangular pits can be dug, and potted aloe vera can be put into the pit, which shall be erected with bamboo pieces and sealed with double-layer plastic film. If the temperature is too low at night, it can be covered with cotton quilt or straw mulch, and the film can be removed in time at noon during the day for ventilation

Watering

Aloe basin soil should be kept dry and watered once in 15 ~ 20 days. When the weather is cold, the watering times can be reduced or not. If the indoor air is dry, spray water on the leaf surface, which can not only remove the dust on the leaf surface, but also reduce the evaporation of water on the leaf surface, which is conducive to keeping the leaves green and green

Topdressing

In addition to the rational application of organic fertilizer, potted aloe should also be topdressed in time, once in 40 ~ 50 days in winter. Generally, urea solution with a concentration of no more than 2% is used for watering, and the concentration of foliar fertilizer should not exceed 0.1%

Illumination

In winter, aloe should see more sunshine. Usually, aloe can be placed in a place sheltering from the wind and facing the sun or on a balcony facing south. It is generally removed after 9 a.m. and moved indoors before 3 p.m. In addition, a transparent plastic bag can also be set outside the plant, which will not affect the sunlight, but also improve the temperature and humidity. The method of covering the plastic bag is: tie an arch support with iron wire at the edge of the flowerpot, put on the plastic bag, wrap the aloe and the basin together, and remove the plastic bag in time when the room temperature increases. Although this method is simple, the effect of heat preservation and overwintering is not bad, but the time of covering the bag cannot be too long. Otherwise, once the sun is exposed, the temperature in the bag will rise and airtight, which will damage the aloe vera
