In answer to your story, nature still does most things better than we will ever do, despite all the effort we seem to put in sometimes.
Although us gardeners do get the upper hand occasionally.

Theres no fool like an old fool.
Nice to be back - I have returned to the world of 9-5 well... 8-6 if you include the traffic but the patch is still my refuge. The lack of time to spend in the garden is the reason the self seeded stuff was left alone. It is a little demoralising when the less effort you put in appears to produce better results
