But the genius of Permaculture is that it's also way less effort. Work with nature, rather than fight it.
Chop and drop. Pull out weeds then drop them on the ground, let it turn into mulch.
The date actually had me wondering. At what point do we start to refer to 1994 as the "1900s". We are already 2 decades into the 2000s, but it feels strange to refer to 1994 as the 1900s? Wonder which decade in the 1900s people started feeling comfortable referring to 1894 as "the 1800s".
In contrast, I think 20th century versus 21st century doesn't feel as wrong, and I regularly use 20th century to refer to time periods that include the 1990s.
It's just a matter of experience and perspective. Many of the permaculture principles have been practiced since long before industrialization. In the scale of human existence, the current "normal" agriculture practices are abnormal, while permaculture is normal.
Also, don't cut the weeds unless you have a very good reason. Even the definition of "weed" is questionable. Most of the time, the "weed" grows where it is actually beneficial.
It really wasn't.

It's interesting that, while the statement is technically true, you pick the number 26.
Bill Mollison & David Holmgren published 'Permaculture One - A Perennial Agriculture for Human Settlements' in 1978.
So it's not only more than 26 years old, it's also more than 41 years old.
