A few things to watch out for:
  • Don't let the trunk of a 'real' Christmas tree touch the carpet as you risk staining from the sap which can drop from the cut base.
  • Be careful filling water containers which feed the tree as spills can accumulate and damage the carpet and underlay.
  • Beware of sharp edges on metal tree supports as these can cut or damage carpets. Put something under to spread the load.
