Care Guide for Ficus binnendijkii 'Amstel King'

  
Light: Bright, indirect light preferred. Tolerates some morning or late afternoon sun. Avoid harsh midday exposure.
  
Watering: Let the top 2–3 cm of soil dry before watering. Avoid standing water and ensure drainage.
  
Humidity: Prefers moderate to high humidity. Benefits from occasional misting in dry air.
  
Temperature: 18–25 °C ideal. Protect from cold drafts and temperature swings.

Fertilizing: Feed every 4–6 weeks year-round with balanced liquid fertilizer. Avoid overfeeding.
  
Repotting: Every 2–3 years or when rootbound. Choose a pot only slightly larger than the current one.
  
Pruning: Light pruning maintains shape. Remove yellowing or damaged leaves as needed.
  
Hydroponics: Can adapt to semi-hydroponics (e.g. LECA) with consistent humidity and root oxygenation.

Troubleshooting Common Problems

  
Leaf drop: Caused by sudden light or temperature shifts. Keep environment stable.
  
Yellow leaves: Often a sign of overwatering or compacted soil. Improve drainage and water less frequently.
  
Brown tips: Linked to dry air or inconsistent watering. Raise humidity and stick to a routine.
  
Pests: Check for mealybugs or spider mites. Treat early with insecticidal soap or neem oil.
  
Root rot: Results from soggy soil. Repot into well-draining substrate and reduce watering.

Extra Tips for Happy Growth

  
Placement: Keep away from vents or drafty windows. East or west-facing rooms are ideal.
  
Support: As it grows taller, a slim stake or moss pole may help support the upright form.
  
Cleaning: Wipe leaves regularly with a damp cloth to remove dust and support photosynthesis.

Toxicity
Like other Ficus species, Ficus binnendijkii 'Amstel King' produces a latex sap that can irritate skin and is toxic if ingested by pets or children. Always wear gloves when pruning and keep out of reach.
