Quick answer
If watering issues overwatering underwatering is what's going on with your Bonsai, the most likely cause is: Bonsai compost becomes hydrophobic when dry and water runs off the surface without penetrating.

Start here:
- 1. 1. Test moisture by inserting finger 1 inch into compost — water only when dry to touch
- 2. 2. For dry compost, stand entire pot in bowl of water and let moisture percolate upward from drainage holes
