Selecting Pot and Soil1. Pot Selection: For Nandina domestica bonsai, it is advisable to use ceramic or purple sand pots with good breathability and drainage.
2. Soil: Nandina domestica prefers fertile, well-draining acidic soil, which can be mixed proportionally with decomposed leaf soil, coarse sand, and matured compost.
Watering and Fertilizing1. Watering: Nandina domestica enjoys a humid environment but avoids waterlogging.

In the hot summer season, the frequency of watering can be increased appropriately.
2. Fertilizing: During the growth period of Nandina domestica, apply a compound fertilizer once a month. In winter, fertilization can be stopped. When fertilizing, it is important to apply thin layers of fertilizer frequently to avoid over-fertilization.
