Glossary

Plain-language definitions for every term used across this site. Every article links back here the first time it uses one of these words.

Canopy layer — The tallest layer of a food forest, made up of full-size fruit and nut trees. Forms the top of the system and shapes light conditions for every layer below it.

Chop-and-drop — Cutting back a fast-growing plant (often a nitrogen fixer or groundcover) and leaving the cuttings on the ground where they fall, rather than removing them. The cuttings break down and feed the soil in place.

Establishment / establishment period — The stretch of time (typically one to three years) between planting and the point where a food forest can largely sustain itself — deep enough roots, closed enough canopy, healthy enough soil — without ongoing intensive care.

Food forest — A planted, multi-layer ecosystem grown for food, designed to organize itself the way a natural forest does, with plants placed to support each other rather than grown in isolated rows.

Forest garden — Used interchangeably with "food forest" in most sources; both terms describe the same layered, perennial-based growing system.

Groundcover layer — Low, spreading plants that cover bare soil, hold in moisture, and suppress weeds by taking up space weeds would otherwise fill.

Guild — A small group of plants placed together on purpose because they help each other — commonly a food-producing plant paired with a nitrogen fixer, a nutrient accumulator, and/or something that draws pollinators or deters pests.

Herbaceous layer — Non-woody perennial plants — vegetables and herbs — filling in at and slightly above ground level.

Nitrogen fixer — A plant (often a legume tree or shrub, such as koa) that pulls nitrogen from the air and makes it available in the soil, feeding other plants growing near it.

Nutrient accumulator — A deep-rooted plant that pulls minerals up from deeper in the soil than most other plants can reach, making those nutrients available near the surface.

Permaculture — A design approach that models growing systems on how natural ecosystems already sustain themselves. The framework behind food forest design, though you don't need the term to use the ideas.

Permaculture zones — A way of laying out a site by how often each part is visited: zone 0 is the house, zone 1 is visited daily, and zones 2 through 5 are visited progressively less often. Used to decide where high-maintenance vs. low-maintenance plantings belong.

Polyculture — Growing many different species together in the same space, as opposed to a monoculture (one crop, grown alone). A food forest is a deliberately designed polyculture.

Root layer — Crops grown underground — kalo (taro) is the primary example used throughout this site — using soil space that nothing else in the guild is competing for.

Shrub layer — Berry bushes and other shrub-scale food plants, filling the space between the tree layers and the ground layers.

Succession planting — Replacing an individual plant, once it dies or ages out of productivity, with something new — ideally filling the same role in its guild — so the system keeps functioning rather than developing a permanent gap.

Understory layer — Smaller or dwarf trees that fill the light gaps the canopy layer leaves open, tolerating partial shade better than full-size canopy trees would.

Vine layer — Climbing plants that use the vertical space on tree trunks or structures, rather than needing ground space or a trellis of their own.

Wet-tropical — The climate classification this site's current content is scoped to (Hawaiʻi and similar regions) — high rainfall, minimal frost risk, year-round growing season. Other climates will get their own content once there's real planting experience behind it.
