great reading about the different methods here
now, i think perhaps a 'food forest' out of seed balls would be difficult but what about say turning a lawn area into a more fertile realm (to establish conditions for a FF) using seed balls - using beneficial and strong plants to take over the lawn? it would take some time though....
and Paul is, I think, right on there - Fukuoka would always time his seed balling...Interesting that Paul had success moreso with direct seeding. I love that footage of Sepp just throwing seeds from a bucket and then going on a treasure hunt to see what made it. But, like Maikeru, I would have endless bird/pest issues
Mark - I didn't quite understand the third method - could you explain a bit further?
