Here are some very quick tips for your Streps.

• You can now move your Streptocarpus plants to a south facing windowsill for maximum light.
  
• If it gets very cold next to the window during the nighttime (especially if they are behind closed curtains), you can move them away from the window each evening.
  
  
• Normal room temperatures should be fine.
  
  
• You can keep feeding plants which are still flowering.
  
  
• As it gets cooler, be careful not to overwater plants.
  
  
• Some leaves may naturally die back and can be removed.
