A permaculture guild is the smallest piece of a self-sustaining food forest: one anchor tree surrounded by 7 to 12 supporting plants that fix nitrogen, suppress weeds, attract pollinators, mine deep nutrients, and shade the soil. The pattern works in every US climate zone, but the species change dramatically between a Vermont apple guild and a Florida mango guild. Here are the 7 functional roles, a guild template for each major US climate zone, and the design principles that make any of them work.
Bill Mollison and David Holmgren coined the term "guild" in Permaculture One (1978) and refined it in Permaculture: A Designers' Manual (1988). A guild is a small, intentional plant community organized around a central productive species, usually a fruit or nut tree. The supporting plants are not random. Each one fills a specific function the anchor tree needs (nitrogen, pest deterrence, mulch, pollinators) so the whole system trends toward self-maintenance over time.
Robert Hart's Forest Gardening (1991) translated the idea into a 7-layer temperate model. Toby Hemenway's Gaia's Garden (2009) made it usable in US backyards. Today the guild is the most popular small-scale permaculture pattern in North America because it scales from a single tree in a 10 ft circle to a 10-acre food forest using the same template.
Climate change is shifting US hardiness zones north by about 1 to 2 zones per generation according to USDA ARS Plant Hardiness Zone data. The guild pattern is climate-resilient by design because it includes redundancy (multiple plants per role), depth (perennials with established root systems), and diversity (10+ species in 100 sq ft). A monoculture orchard fails when its one species hits a heat or pest threshold. A guild absorbs the shock and keeps producing.
A well-designed guild fills all 7 roles. A minimal backyard guild can combine roles (one ground cover that also fixes nitrogen, like clover) and skip the sub-canopy if the bed is small.
The USDA Plant Hardiness Zone Map divides the US into 13 zones based on average annual minimum temperature. For permaculture purposes, focus on these 6 climate regions:
| Climate region | USDA zones | Min winter temp | Anchor tree options |
| Cold temperate | 3-5 | -40 to -10 deg F | Apple, pear, plum, sour cherry, hazelnut |
| Cool temperate | 5-7 | -20 to 10 deg F | Apple, pear, peach, persimmon, chestnut |
| Warm temperate | 7-9 | 0 to 30 deg F | Peach, fig, pomegranate, pecan, persimmon |
| Mediterranean | 9-10 | 20 to 40 deg F | Olive, citrus, fig, almond, loquat |
| Subtropical/Tropical | 10-11+ | 30 to 50+ deg F | Citrus, avocado, mango, banana, papaya |
| Arid/Desert | 8-10 SW | 10 to 30 deg F (dry) | Mesquite, jujube, pomegranate, olive, almond |

Canopy: cold-hardy apple (Honeycrisp, Liberty, Northern Spy). Sub-canopy: hazelnut or American plum. Shrub: black currant, gooseberry. Herbaceous: comfrey, yarrow, garlic chives, lupine (nitrogen-fixer). Root: garlic, daffodil (pest deterrent, gopher repellent). Ground cover: white clover, strawberry. Vine: scarlet runner bean (annual, nitrogen-fixing). Mark Shepard's New Forest Farm in Wisconsin (zone 4b) is the largest documented US example of cold-temperate guilds at scale.
Canopy: apple, pear, or Asian pear. Sub-canopy: elderberry or seaberry (sea buckthorn, nitrogen-fixing). Shrub: blueberry, currant, raspberry. Herbaceous: comfrey, oregano, mint (contained), dill, fennel (use sparingly, allelopathic). Root: garlic, daikon radish (subsoiler). Ground cover: Dutch white clover, wild strawberry. Vine: hardy kiwi, grape. Eric Toensmeier's Paradise Lot in Holyoke, MA (zone 6a) documents 200+ species in a tenth of an acre using this template.
Canopy: peach, nectarine, or fig. Sub-canopy: redbud (nitrogen-fixing), serviceberry. Shrub: blueberry, blackberry, pomegranate. Herbaceous: rosemary, lavender, oregano, comfrey, garlic chives, asparagus. Root: garlic, walking onion, sunchoke. Ground cover: creeping thyme, white clover. Vine: muscadine grape, passionflower. The longer growing season here lets you stack more species and harvest from spring through fall.
Canopy: olive (Mission, Manzanillo, Arbequina) or citrus. Sub-canopy: almond, loquat, pomegranate. Shrub: rosemary, sage, lavender (all serve dual roles as herbs and insectary plants). Herbaceous: artichoke, calendula, oregano, thyme. Root: garlic, leek, walking onion. Ground cover: fava bean cover crop in winter (nitrogen), creeping thyme in summer. Vine: grape, passionflower. This template handles 6-month summer drought and tolerates poor soil. Water deeply but infrequently.
Canopy: mango, avocado, or coconut. Sub-canopy: banana, papaya, pigeon pea (nitrogen-fixing). Shrub: pineapple, cassava, sugarcane (in tropical, treat as shrub-height). Herbaceous: lemongrass, sunflower, sweet potato leaves, malabar spinach. Root: taro, sweet potato, ginger, turmeric, cassava root. Ground cover: sweet potato vine, tropical legumes. Vine: passionfruit, chayote. Tropical guilds stack more plants per square foot than any other climate because year-round growth means continuous yields. Banana is the workhorse: its broad leaves shade soil, its trunk fiber mulches in place when chopped, and it produces in 9-12 months.
Canopy: mesquite (nitrogen-fixing, drought-tolerant, native), jujube, or pomegranate. Sub-canopy: desert ironwood, palo verde. Shrub: prickly pear cactus, agave, wolfberry. Herbaceous: native sages, yarrow, calendula, native grasses. Root: desert-adapted garlic, walking onion. Ground cover: low-growing native ground cover sedges. Vine: passionflower (native species), grape. Water management is the limiting factor. Use earthworks (swales, basins) to capture and slow runoff, mulch heavily (4 to 6 inches / 10 to 15 cm), and choose desert-adapted varieties of every species.
Choose a productive species that thrives in your climate region. For uncertainty, pick something one zone hardier than your current zone to buffer climate shifts. Check chill-hour requirements (apple needs 800+ hours below 45 deg F / 7 deg C; mango needs none). Confirm root-zone soil drainage and sun exposure (most fruit trees need 6+ hours direct sun).
For each of the 7 roles, list 2-3 species options that work in your climate. Use Hemenway's Gaia's Garden appendix or your state extension service's perennial plant list. Cross-reference: any species that fills two roles (a shrub that also fixes nitrogen, like seaberry) is a high-value pick.
Buy from nurseries in your climate region. Food Forest Collective maintains a regional nursery directory. Avoid generic big-box plants which are usually not climate-adapted to your zone. Year-1 plant budget: $80 to $250 for a complete 12 ft (3.6 m) backyard guild.
Plant the anchor tree in the center. Sub-canopy at 8 to 12 ft (2.4 to 3.6 m). Shrubs at 4 to 6 ft (1.2 to 1.8 m). Herbaceous layer at the drip line. Ground cover fills any bare soil. Vines plant on the north side of the anchor and trained upward. Mulch heavily (3 to 4 inches / 7.5 to 10 cm wood chips) immediately after planting.
Year 1: plants establish; expect heavy mulching, frequent watering, weed pressure. Year 2: ground cover fills in, weed pressure drops. Year 3: guild is self-managing; replace any plant that died or underperformed. Most US guilds reach full production at year 5 to 7 for fruit trees, with vegetable and herb layers producing from year 2 onward.
The USDA updated the Plant Hardiness Zone Map in 2023 and confirmed what most US growers already see in their gardens: zones have shifted north. New York City moved from zone 7a to 7b. Minneapolis moved from 4b to 5a. The USDA Climate Hubs publishes regional climate-shift forecasts. Practical implications for guild design:
This is permaculture's first principle in action: observe and interact. The zones map you grew up with is not the map you will design with in 20 years.

Read the Free GuideA permaculture guild is a designed plant community organized around a central anchor tree (usually a fruit or nut tree), with 7 to 12 supporting plants that each fill a specific ecological role: nitrogen fixation, pollinator support, pest deterrence, mulch production, soil building, and yield diversification. The pattern was developed by Bill Mollison and David Holmgren in the 1970s.
A minimal backyard guild has 7 to 12 species filling the 7 functional roles. A larger guild can include 30+ species. The key is functional diversity, not species count: each of the 7 roles (canopy, sub-canopy, shrub, herbaceous, root, ground cover, vine) needs at least one plant.
Backyard guilds are typically 8 to 12 ft (2.4 to 3.6 m) in diameter for a semi-dwarf anchor tree. Standard-size anchor trees need 20 to 30 ft (6 to 9 m). A small urban guild can fit in a 6 ft (1.8 m) circle if you use dwarf rootstock.
Companion planting is short-term, usually annual: tomatoes with basil for one growing season. A guild is long-term, perennial, and organized around a central anchor tree that lives for decades. Guilds are designed around the 7 functional roles; companion planting is usually pairwise associations.
A guild is the smallest unit. A food forest is many guilds connected together, usually with interlocking canopies and shared ground cover. A single guild fits in a backyard; a food forest typically requires a quarter-acre or more.
For most US zones (4 to 7), an apple on semi-dwarf rootstock is the most forgiving choice: disease-resistant cultivars exist, plant availability is high, chill hours match most temperate climates, and dozens of well-documented guild plant lists exist for apple specifically.
Start with your USDA hardiness zone. Pick an anchor tree that thrives in your zone (and ideally one zone colder to buffer climate change). Then fill the 7 functional roles with species adapted to your climate, soil, and water availability. Source from regional nurseries that grow climate-adapted varieties.
Yes. A single guild fits in a 10 to 12 ft (3 to 3.6 m) circle with a dwarf anchor tree. Even an 8 ft (2.4 m) circle works with the smallest dwarf rootstock and ground-cover-only lower layers. Urban gardeners use containers for the herb and root layers and plant the anchor tree in the only ground available.
Vegetable and herb layers produce from year 2. Shrubs (currants, blueberries) fruit by year 3. Fruit trees typically begin producing at year 4 to 7 depending on rootstock and species. Full productive maturity is year 7 to 10.
Yes, more than monoculture orchards or vegetable beds. Deep mulch (3 to 4 inches / 7.5 to 10 cm), perennial root systems, and high plant diversity dramatically reduce water demand. Mediterranean and arid guilds are specifically designed around drought tolerance with species like mesquite, olive, lavender, and native sages.
