1. Illumination

Potted plants of lemon trees prefer plenty of sunshine. Therefore, during maintenance, they must be placed in the courtyard or balcony and other places with sufficient light. If the light is insufficient, lemon trees will grow in vain and only grow leaves without flowering, which will seriously affect the yield of lemon. However, when the sun is strong in summer, appropriate shading treatment must be carried out to prevent sunburn of leaves

2. Place

There are some thorns on the branches of the lemon tree. Therefore, during maintenance, the lemon tree must be placed in a safe place. If children or pets touch it, they will be stabbed. In addition, the juice in the leaves of the lemon tree is toxic and can not be eaten casually. If it is eaten by children by mistake, poisoning may occur, usually diarrhea and vomiting, which will seriously harm the child's body

3. Temperature

The suitable growth temperature of lemon tree is 15 ~ 25 ℃. Lemon tree is neither cold nor heat resistant. Therefore, it must be moved indoors in winter, or wrap the plant with plastic bags and quilts for thermal insulation, otherwise the lemon tree will suffer from freezing injury. When the climate is hot in summer, you must put the lemon tree in a cool place, otherwise the lemon tree will be sunburned. You can also spray some water on the leaves of the lemon tree or in the surrounding air to cool down

4. Pruning

Lemon trees have many branches, so they should be pruned in time, otherwise it will affect the light of other branches and better ventilation. The old branches and sick branches can also be pruned, which can reduce the consumption of nutrients and affect the yield of lemon. Pruning is generally carried out in spring and autumn, and it is best to prune after rain, so as to speed up the healing of wounds
