The Seven Levels of a Forest Garden

The following I learnt from Steve Watts, permaculture expert, during a talk he gave about Forest Gardens at the wonderful Coedfest, which he co-leads.


In a forest garden, plants and trees are layered over one another to create a growing system that is far more productive and diverse than farming a single crop on an area of land.

By stacking layers of complementary plants and trees over one another, you increase the amount of carbon that is being locked in, you increase the leaf litter that falls and so you increase the richness of the soil.

As Steve describes we can think of a forest garden has having seven layers:

  • High trees,
  • Lower trees,
  • Tall shrubs,
  • Small shrubs,
  • Ground cover,
  • Plants in which we harvest the roots, and

  • Climbers.

Each of these layers can produce food at different times of the year, and each of these layers provides a complementary role to the others. It is a beautiful model for a stacked system that is creating life. And it is a reminder that when we bring different systems together in complementary ways we can create much greater richness and diversity than we keep things separate.

Too soon to decide?

Sometimes, when faced with a decision, it’s worth asking: is it too soon to decide?

In permaculture, it’s common practice to wait a whole season before planting anything. That way, you can observe the full cycle: how the sun moves, where water pools, which areas dry out, and what emerges from the seed bank.

Without seeing the full pattern of a cycle in motion, we risk deciding too early — acting on partial data.

And this principle isn’t just for seasonal systems. It applies to any emergent situation. If we make our decision before more factors reveal themselves, we may find we acted too early.

So how do we know when it’s the right time to decide?

We might try to assess the nature of the change: is it cyclical? Is it reaching a steady state?

But in many situations, we can’t know for sure. That’s why we need to engage for the long term — not just to decide, but to learn to work with system over time. This is when we shift from one-off decision-makers to long-term stewards of systems. Over time we can then tune our instincts for how — and when — to intervene.
