1. Fertilization: generally, citrus with different length of time needs different fertilizer management. If it grows for about one or two years, it can spray fertilizer on its leaf surface. Some fertilizer containing nitrogen with low concentration can be applied to the soil, and then some phosphorus fertilizer or potassium fertilizer can be added to assist its growth. The citrus that has been cured for a long time needs to be moderately added with some urea to improve the number of results

2. Pruning: it's better to prune the plant according to its growth. Generally speaking, if it grows a little stronger, it needs to be greatly pruned. It's better to be a little ahead of time. If the tree is not growing well, it can be cut less, and the pruning time can be moderately delayed. When pruning, you can repair the staggered branches or overlapping branches

3. Light: it should be given sufficient light level, which can make its leaves more green and shiny, and the fruits are more sweet and delicious

4. Moisture: the humidity should not be too high. Just keep its soil slightly moist, so as to ensure that the plant grows more vigorously
