Know your trees

There I was doing a bit of research about permaculture in readiness for our proposed permaculture garden and I came across this brilliant series of videos on how to identify trees. They are presented by Patrick Whitefield, the great permaculture guru. If you've ever gone for a walk in woodland and wished you knew the names of trees you see, this could be the answer. This is Number 2 and there are 4 in all. Watch out for the bit on ivy in this one. I meet many people who hate ivy and rip it out of their gardens. Yes it can get a bit out of hand, but it's not the villain you may think it is. In fact, it does a lot of good and does not harm trees.
