The Christmas Tree graveyard in Manor House Hardens is already filling up.
Lewisham Council offers this advice on how to dispose of your tree:
After Christmas, you can take your real Christmas tree to a collection point near you. If you have a garden waste bin, you can use it to recycle your real Christmas tree. Just cut it into pieces no bigger than 10cm thick and 50cm long. Find out more about our garden waste collection service. You can donate artificial trees to a charity shop or give them away. If it’s broken, take it to the Landmann Way Reuse and Recycling Centre.
You can find details of other collections points here.
