there was a guy on Dragons Den, dont know if any of you watch it last week who solved this problem.

It was a like has been suggested basically a sheet which decorates the plant pot most trees sit in, and when wanting to remove the tree came up and over the top, completely sealing the tree and at the top with a draw string. like a sleeping bag.

Simply remove the tree outside, and then undo the cover leaving the mess away from the house.

i thought it was a great idea but he was shot down by the dragons.

Id use a bed sheet, or better still buy a plastic tree - no mess
