nutrient deficiency on Bonsai
Quick answer
If your Bonsai has nutrient deficiency, the most likely cause is: Bonsai are cultivated in limited soil volume, which depletes nutrients rapidly. The restricted root system cannot access external nutrients, making fertilizer application essential for maintaining tree health and vigor.
Start here:
- 1. Use bonsai fertilizer containing nitrogen, phosphoric acid, and potash (NPK)
- 2. Add fertilizer containing chelated iron to prevent chlorosis
