I see this is an old post, but the information still needs to be shared, so...
I have a little idea. Not one to reach millions, but smaller numbers that may be inspired to action.
One of my goals on my acre
is to build it into something like a display garden/yard. I'm still in very early stages, but I hope that a decade down the road, I'll be able to open my land
to visitors (on garden tours, or to buy art
and veggies and tour the land as part of that.) By having that as one of my goals, I'm motivated to do my very best work because the more amazing it ends up being, the more I can inspire visitors to try a different way. And when people
see things up close and personal, and they talk to you and get their questions answered, and they feel awe ("you barely water
AND have 20 kinds of fruit
growing here AND veggies of every kind?!")... they are more likely to want to try it for themselves. I think
this has the potential to impact people in a deeper way.
Yes, for me this is a long term project and I'm not there yet, but I bet there are plenty of people who are so much further along in their journeys and have established hugelkulture beds/properties... these people should
consider opening up to visitors on garden tours. And be there to talk and educate one on one.
