1、 Basin changing method

1. Time for changing pots: it is recommended to change pots every spring, especially in March and April. At this time, the climate is suitable and the temperature has picked up. After changing pots, the plants will resume growth as soon as possible without affecting flowering

2. De potting treatment: plants preparing to change pots shall be cut off in advance to facilitate de potting. Just turn the plant upside down when removing the pot to minimize root damage. If it is raised in a plastic pot, you can also cut the flowerpot directly

3. Pruning root system: after removing the pot, cut off some old roots, withered roots and poorly growing roots, disinfect them after reduction, and dry them properly to avoid infection

4. Prepare pot soil: the flower pot should be slightly larger than the old pot, so that there is more room for growth. The soil should be breathable and loose. The original soil mass can be dispersed and replaced with new soil, or one third of the new soil can be replaced

5. Pot planting: after preparing the soil, you can directly plant in the pot. If all the soil is changed, put an appropriate amount of soil first, and then put it into the plant fill for compaction. If only part of the soil is changed, directly put the soil mass into a new basin and add an appropriate amount of soil

2、 Deep basin or shallow basin

Just replace it with a shallow flowerpot. Its growth rate is relatively fast and it is easy to burst. It's best to plant in a shallow basin with a slightly larger caliber, so that the later flowering will be more ornamental
