When planting orange trees in pots, we should choose a soft and breathable substrate with rich humus content, which can be mixed with humus soil+garden soil+sand. This substrate has good drainage and permeability, which is beneficial to the growth of its roots. The container should be a flowerpot with large caliber, and the bottom of the flowerpot should be provided with drainage holes to ensure good drainage and air permeability. Potted soil should be replaced every 1-2 years to avoid long-term use of soil hardening affecting its growth.

2. Adequate lighting

Orange trees have high requirements for light, so try to choose a place with long light time and good ventilation when maintaining. Potted plants are mostly maintained indoors and need to be placed in balconies, living rooms and other places with good light to avoid yellowing and leaf shedding caused by long-term shading.

Step 3 water properly

The demand of orange trees for water is different in different seasons, so it is enough to ensure that the soil is completely dry in spring and autumn, and the watering times need to be reasonably adjusted according to the size of potted plants and soil drainage. In summer, when the temperature is high, the water evaporates faster. It is best to check the dryness and wetness of the basin soil every morning and water it properly.

4. Rational topdressing

When fertilizing, organic fertilizer is the main fertilizer. In vigorous spring, a certain amount of decomposed organic fertilizer can be applied every 20 days to promote root growth. When applying fertilizer, the fertilizer should be applied near the roots, and then diluted with water to make the roots absorb reasonably.

Matters needing attention in potted orange trees

Potted citrus reticulata needs frequent pruning in the cultivation process, which can increase the lighting effects. If the branch of the main branch is too long, it can be truncated to avoid the top effect, and a branch can retain about 6 side branches. Because the pot is small, the soil is small and the nutrition is limited. Through pruning, the rational distribution of nutrients in the tree can be adjusted, so that limited nutrients can be supplied to buds and leaves in a concentrated way, and more fruit branches can be formed, thus achieving the purpose of full flowering and fruiting.

When the number of flower buds in orange trees is large, the flowers should be thinned during bud pregnancy and the fruits should be thinned after physiological fruit drop. If there are few buds, you can leave more flowers. Simultaneously carrying out artificial pollination.

Spray water during flowering to prevent it from raining during flowering. Don't spray water on blooming flowers, which is not conducive to pollination and is easy to cause rotten flowers.

If diseases and insect pests occur in citrus reticulata, it will also cause plants not to bloom. The common disease is anthrax. After discovery, the plants should be sprayed with carbendazim solution in time for control.
