Geoff takes on one of the biggest misunderstandings in sustainable agriculture: the myth of the “invasive” plant. In this walk-through of a living food forest, he shows how fast, aggressive species aren’t a threat when you understand succession—they’re hard-working allies that build soil, shape structure and push the whole system toward long-term abundance.
Geoff’s Online Permaculture Design Course includes weekly video Q&A sessions where he answers student questions. This one comes from the 2019 archive. Learn more about Geoff’s online courses at https://www.discoverpermaculture.com.
Key Takeaways:
- 00:00 – 00:40: Fast-growing “invasives” aren’t villains—they’re specialists that rush in to repair damage, build soil, and stabilize a site faster than anything else.
- 00:40 – 01:34: Acacias and clumping bamboo work together to control the ground, add carbon, and prepare the way for long-term species.
- 01:34 – 02:11: Old root systems and stumps break down slowly, acting like buried compost piles that feed the soil for years.
- 02:11 – 03:16: Strategic pruning of overstory legumes keeps energy cycling into the forest floor, helping succession race ahead.
- 03:16 – 04:20: Leucaena—often labeled a weed—is a nutrient powerhouse when managed through regular cutting. Our prejudice against “successful” species blinds us to their value.
- 04:20 – 05:11: Casuarina fixes nitrogen and phosphate while supporting climbing crops like yam, stacking multiple functions into one tree.
- 05:11 – 06:12: Dense groundcovers trap organic matter, creating the fungal soils that trees rely on. The species matters less than the function.
- 06:12 – 07:46: By stacking short-, medium-, and long-term species, you transform a “weedy” site into a self-maintaining food forest.
- 07:46: Novel ecosystems made of mixed species—native and non-native—can be incredibly productive and ecologically beneficial when placed intentionally.

About Geoff:
Geoff is a world-renowned permaculture consultant, designer and teacher who has established demonstration sites in many of the world’s major climates. He’s dedicated his life to sharing permaculture design and inspiring people to care for the earth, care for each other and return the surplus.
About Permaculture:
Permaculture weaves land, resources, people and the environment into a single, supportive system. It mirrors how nature works—no waste, no shortcuts, just smart relationships. The tools are wide-ranging: water harvesting, soil building, energy systems, forestry, natural building, aquaculture, appropriate technology, community development and more. Whether you’re on acreage or in an apartment, these principles scale beautifully.
