If you've just watched the last episode of Autumnwatch this evening then you'll have seen mention of Tree O'Clock, an effort to plant a record number of trees in a single hour across the country. The hour in question is 11-12 on 5th December (a Saturday) and apparently over 260,000 are pledged to be planted.

The best bit is that free trees are being given away by what seems to be just about every garden centre in the country (including DIY stores like Homebase) judging by the list.

You may have to wait several lifetimes for your tree to achieve the sort of girth pictured on the right, but you have to start somewhere!
