 It's been fantastic to be at the conference here, it's been very interesting listening to all the speakers, understanding the work and the cooperation that's going on internationally about these important issues. But the thing that I've really taken from it is that we can all do something to understand good gardening practice, which results in good plant health and good soil health. We should all remember that if we travel, like so many of us have traveled to this great city of London, if you travel anywhere, leave what you see growing behind you. The risk of importing pests or diseases through what we think of as beautiful plants, which may not be suitable for our climate or may introduce some alien species that cause devastation to our food systems or to our gardens.
