Bracken eradication

My latest thoughts on 'organic' fern eradication:

At the moment I'm scything every few days - this seems to be resulting in more and more shoots (presumably the fern rhyzomes are desparately trying to put up some ferns). In early June (when I'm in England) no scything will happen and presumably there'll be a multitude of young ferns when I get back. I hope there are so many that the sugar stores in the rhyzomes will be exhausted by the volume of new growth. Mid-June I'll cut everything back to the ground. No doubt there be some regrowth so I'll follow the same procedure, generally cutting when the ferns are as high as possible but not yet in leaf. Perhaps early July and the end of July. I'll continue to use garlic which I suspect works a bit like a mild form of 'roundup' - the garlic juice descending via the cut stem and reacting with the rhyzome. If there are no leaves to replenish the sugar supplies in the rhyzomes and no ferns are allowed to reach maturity and spread spores, I reckon they have to die out...eventually.
