How to care for your Hydrangea Seemannii

  • Light: This plant thrives in bright, indirect light but can tolerate some shade.
  • Water: Water the plant regularly and keep the soil evenly moist, but not waterlogged. Allow the top inch of soil to dry out slightly before watering.
  • Soil: Use a well-draining potting mix and make sure the pot has drainage holes to avoid water accumulation.
  • Humidity: It likes high humidity, so consider using a pebble tray or a humidifier to increase the moisture in the air.
  • Fertiliser: Feed the plant with a balanced liquid fertiliser every two weeks during the growing season and monthly during the dormant season.
  • Pruning: Prune dead or yellowing leaves and stems as needed. Cut back the plant to encourage bushier growth and to keep its size under control.
