🌱 How to Care for Sweet Plum to Prevent Scale Insects?

💧 How to Water

The substrate should always be kept slightly moist—water as soon as the top layer has dried out. The Sweet Plum is very sensitive to drought; even a single missed watering can cause leaves and branches to dry up. However, avoid waterlogging in the pot and use soft, lime-free water if possible.

☀️ Lighting

Choose a bright location with plenty of indirect light, protecting it from harsh midday sun in summer. Indoors, a spot near a south- or west-facing window is ideal; if light is insufficient, a grow light can be used.

🪴 Ideal Soil

Use a well-draining, slightly acidic to neutral bonsai substrate, such as a mix of Akadama, lava granulate, and some peat moss or gravel. Good drainage is essential to ensure the roots never sit in water.
