To prepare soil, you can mix humus soil, garden soil, and sand to make a cultivation substrate, and use earthenware pots as cultivation containers; for water and fertilizer management, you need to water thoroughly every time but should not produce stagnant water. It is necessary to apply decomposed organic fertilizer every half a month; for sufficient light, it needs to be placed in a brightly lit environment for maintenance and given more than 8 hours of light. 1. Preparing soil

In order to increase the yield and quality of orange trees, loose, fertile and acidic soil needs to be selected for cultivation. When mixing soil, humus soil, garden soil, and sandy soil can be mixed to make a cultivation substrate. Choose a tile pot with strong air permeability as a cultivation container. Before placing the pot in the pot, you need to spray diluted ferrous sulfate solution into the soil to make the soil slightly acidic. 2. Water and fertilizer management

Due to the small growth volume of potted orange trees, the application of water and fertilizer needs to be strictly controlled during the maintenance period. Watering needs to be done thoroughly but should not cause stagnant water. Apply water in small amounts and often. It is also necessary to apply diluted decomposed organic fertilizer or liquid fertilizer every half a month to improve fruit yield and quality. 3. Sufficient light

In order to make the potted orange tree bear fruit as soon as possible, it needs to be placed in an environment with sufficient astigmatism for maintenance. It should be given no less than 8 hours of light every day to allow the branches and leaves to grow. Fully carry out photosynthesis and promote flower bud differentiation of branches and leaves, allowing potted orange trees to grow more robustly. 4. Prune and cut leaves

In order to increase the yield of potted orange trees, pruning needs to be done in time every spring. You can use sterilized sharp scissors to trim off the growth on the plants. Branches that are too dense, overlapping, and growing thin can avoid competing with the main branches for nutrients, thereby increasing fruit yield and quality.
