Is Sweet Plum Bonsai Indoor or Outdoor?
A Chinese sweet plum bonsai grows best outdoors in warm climates, but it can also be kept indoors if provided with bright, indirect sunlight and proper humidity.
Detailed Explanation:
- Outdoor placement: Ideal for tropical or subtropical regions; prefers partial sunlight with shade in the afternoon.
- Indoor placement: South or east room, with a window giving 4-6 hours of filtered sunlight.
- Temperature range: 60–80°F (15–27°C) is optimal.
- Humidity: Maintain 50–70% humidity using a pebble tray or humidifier when grown indoors.
💡 Pro Tip: Most Sweet Plum bonsai care instructions say that you should rotate the bonsai to prevent it from stretching and to encourage it to grow bushier.
Watering Your Sweet Plum Bonsai Tree
Watering is most important for the proper care of sweet plum bonsai. The tree thrives in moist, well-draining soil, and the soil must not be too dry or too wet.
- Frequency: Water daily during the growing season (spring–summer) and every 2–3 days in winter.
- Method: Use a fine mist watering can to soak the entire soil surface until water drains from the bottom.
- Check: Stick your finger 1 inch deep — if dry, water immediately.
- Avoid: Letting the soil dry completely or leaving water standing in the tray.
💡 Tip: During summer, mist the leaves occasionally to maintain humidity and prevent leaf burn.
Ideal Soil Mix for Bonsai Sweet Plum
This mixture will provide the needed aeration while also keeping nutrients. Soil nutrients must be restored every year using liquid bonsai fertilizer or organic compost.
Best Soil Mix Recipe:
- 40% Akadama (clay granules)

- 20% Lava rock
- 10% Organic compost or pine bark
This mixture ensures both aeration and nutrient retention. Replenish soil nutrients annually using organic compost or liquid bonsai fertilizer.

- Frequency: Every 2 weeks in spring and summer; once a month in autumn.
- Method: Apply liquid fertilizer after watering to prevent root burn.
- Pause fertilization: During winter dormancy or after repotting.
