A food forest is not a garden with trees in it. It’s a designed system that mimics the structure of a woodland edge - multiple vertical layers, each occupied by a productive species, each supporting the others through shade management, nutrient cycling, and ground cover. Done right, it reduces your inputs every year while increasing output. Done wrong, you have a canopy tree that shades out everything underneath it by Year 6, and a lot of dead shrubs.
The concept was formalized by Robert Hart at his Wenlock Edge property in Shropshire starting in the 1960s and documented in Forest Gardening (1991). Martin Crawford expanded the practical framework in Creating a Forest Garden (Green Books, 2010), which remains the most complete design and species reference available. Both Hart and Crawford describe a seven-layer system. This article uses that framework, applies it to a 1,000 square foot (roughly 32x32 ft) urban or suburban lot section, and runs the 10-year economics honestly.
The honest part matters. Food forests take time. If you start planting this spring, you will not have meaningful tree fruit until Year 8 at the earliest. Plan for that.
The Seven Layers
The layers exist because every vertical zone in a woodland is inhabited by something. The goal is to fill those zones with species that produce food, fix nitrogen, attract beneficials, or serve multiple functions simultaneously. Hart’s original model (1991) identified seven distinct ecological layers; Crawford’s later work (2010) added the eighth (aquatic), but for a 1,000 sq ft suburban plot, seven is what you’re working with.
Layer 1: Canopy
The highest layer. In a natural woodland, these are the dominant trees - oaks, beeches, maples. In a food forest at home scale, you want fruit and nut trees that top out at a manageable height, ideally on semi-dwarf or dwarf rootstock.
Practical species:
- Apple (Malus domestica) on semi-dwarf rootstock (M.7 or MM.106) - tops out at 12 to 15 feet, begins bearing in Years 4 to 7. Zone 3-9. For a 1,000 sq ft planting, one semi-dwarf apple is the maximum if you want to maintain understory. Full-size apple on M.111 will eventually shade out a 400 sq ft radius.
- Pear (Pyrus communis) on semi-dwarf - similar sizing to apple, slightly more upright growth habit, which preserves more light for lower layers. Years 4-7 to bearing.
- Mulberry (Morus rubra or Morus alba) - fast-growing, heavy producer, and self-fertile. The downside is vigorous growth that requires management. ‘Illinois Everbearing’ and ‘Oscar’ stay somewhat compact in a managed system. Zone 5-9.
Canopy choice is the single most important design decision in a small food forest. On 1,000 square feet, one canopy tree is the practical limit. Two full-size trees on that footprint will eventually close the canopy and end production from everything below them.
Layer 2: Sub-Canopy (Understory)
Trees and large shrubs that grow under the edge of the canopy, typically 6 to 15 feet tall. These are often your most valuable food producers in the mid-term because they begin bearing well before the canopy tree reaches full size.
Practical species:
- Serviceberry (Amelanchier canadensis or A. laevis) - produces edible berries in late spring, Zone 3-8. Tolerates partial shade once established. Hart (1991) specifically noted serviceberry as an ideal understory companion for apple in humid temperate climates.
- Pawpaw (Asimina triloba) - native to Eastern North America, Zone 5-8. Largest edible fruit native to the continent. Requires two genetically distinct plants for pollination. Tolerates significant shade as a juvenile but needs some sun to produce fruit. ‘Shenandoah’ and ‘Susquehanna’ are reliable named varieties.
- Elderberry (Sambucus nigra subsp. canadensis) - fast-growing, begins producing berries in Year 2 to 3, Zone 3-9. Nitrogen-responsive; comfrey chop-and-drop at its base speeds establishment. ‘Adams’ and ‘Bob Gordon’ are high-yield cultivars widely used in small-scale production.
Layer 3: Shrub
The shrub layer occupies 3 to 8 feet, fills the gaps between sub-canopy trees, and in most home food forests is the heaviest producer per square foot during the first decade. These plants begin yielding in Years 2 to 4 and are fully productive by Year 5.
Practical species:
- Black currant (Ribes nigrum) and red currant (Ribes rubrum) - some of the most productive small fruits per square foot available to Zone 4-7 growers. Ben Sarek and Ben Hope are compact black currant varieties suited to smaller plantings. Crusader and Rovada for red.
- Gooseberry (Ribes uva-crispa) - tolerates more shade than most shrubs, which makes it valuable in the inner zones of the planting. Invicta and Pixwell are reliable disease-resistant varieties. Zone 3-7.
- Aronia (Aronia melanocarpa, black chokeberry) - native to eastern North America, extraordinarily cold-hardy (Zone 3-8), drought-tolerant once established, and extremely high in antioxidants. Astringent fresh but excellent for juice, jam, and wine. Viking is the standard named cultivar. Retail price for fresh aronia runs $4 to $7 per pound at farmers markets (USDA AMS specialty crop data, 2023).
- Hazelnut (Corylus americana or C. avellana) - begins producing nuts in Years 3 to 5, Zone 4-8. American hazelnut is more disease-resistant in eastern climates. Plant two varieties for pollination. Competes well in partial shade.
Layer 4: Herbaceous
Non-woody plants that die back in winter and re-emerge annually. In a food forest these are primarily dynamic accumulators and insectary plants - species that do work for the system rather than just occupying space. Some are also food crops.
Practical species:
- Comfrey (Symphytum officinale or S. × uplandicum ‘Bocking 14’) - the single most important herbaceous species in a temperate food forest. Deep taproots (up to 6 feet) mine subsoil minerals, particularly potassium. Chop-and-drop two to three times per season to build mulch layer at the base of trees. ‘Bocking 14’ is a sterile cultivar that won’t self-seed aggressively.
- Yarrow (Achillea millefolium) - insectary plant that attracts predatory wasps and hoverflies. Crawford (2010) documents yarrow as a consistent beneficial-attracting species in his Agroforestry Research Trust trials.
- Mint (Mentha spp.) - contained in the ground layer, mint’s volatile oils confuse aphid navigation. It spreads aggressively; plant in a buried container or accept managed encroachment.
- Chives (Allium schoenoprasum) - allium compounds are documented as deterrents for aphids and apple scab fungal spores (Venturia inaequalis). Plant under and around the canopy tree.
Layer 5: Ground Cover
Low-growing plants that cover bare soil, suppress weeds, retain moisture, and provide some harvest. Ground cover is often planted throughout the whole system at establishment and fills in as other layers develop.
Practical species:
- Strawberry (Fragaria × ananassa) - productive, spreads via runners to fill gaps, edible fruit from Year 2. Tolerates light shade. June-bearing varieties for bulk harvest; everbearing for fresh use through the season.
- Creeping thyme (Thymus serpyllum) - low, fragrant, pollinator-attractive. Tolerates foot traffic; useful at path edges within the system.
- Sweet woodruff (Galium odoratum) - does well in shadier zones where strawberry struggles. Not a food crop but an effective ground cover in deep-shade areas beneath the developing canopy.
Layer 6: Root/Rhizosphere
Underground crops that use vertical root space without competing for above-ground light.
Practical species:
- Garlic (Allium sativum) - planted in fall, harvested in early summer before maximum canopy shade develops. Can be interplanted throughout the system annually. See the garlic growing guide for detailed economics.
- Jerusalem artichoke (Helianthus tuberosus) - extremely productive, Zone 3-9, but aggressive spreader. Plant only in contained zones or where you’re comfortable with permanent occupation. Yields 1 to 2 lb of tubers per square foot in establishment-year conditions (USDA ARS crop data).
- Horseradish (Armoracia rusticana) - perennial root crop, Zone 3-9, tolerates partial shade, essentially impossible to eliminate once established. Excellent companion for the canopy tree zone where it deters some borers. One plant per system is sufficient.
Layer 7: Vine
Vertical climbing plants that use the structure of canopy and sub-canopy trees and any installed trellising to reach light without requiring ground space.
Practical species:
- Hardy kiwi (Actinidia arguta) - produces grape-sized, smooth-skinned kiwi fruit, Zone 4-8. Requires male and female plants (1 male to 6 females). ‘Issai’ is self-fertile and a practical choice for small systems. Heavy producer once established (Year 4-6). Crawford (2010) documents yields of 30 to 50 lb per mature plant.
- Grape (Vitis labrusca hybrids for cold climates) - Concord, Marquette, Frontenac for Zone 4-6. Trellised along the south fence of the system, not up through the canopy tree.
- Hops (Humulus lupulus) - grows 20 to 25 feet per season, dies back in winter. Zone 4-8. Provides fast biomass and dense summer shade on a trellis while the rest of the system establishes.
1,000 Square Feet: A Realistic Stocking Plan
A 32x32 ft plot is enough for a functional multi-layer system if you don’t overplant the canopy. This is a Zone 5-7 species list for a north-temperate planting.
The most common beginner mistake is putting in two or three full-size canopy trees. Within 5 years they close the canopy, ground-level light drops below 10% full sun, and currants, strawberries, and herbs decline or die. Choose one canopy tree, choose the rootstock carefully, and plan your understory around its eventual shadow.
Stocking list:
| Layer | Species | Qty | Spacing | Mature Footprint |
|---|---|---|---|---|
| Canopy | Apple (‘Liberty’) on M.7 semi-dwarf | 1 | Center of plot | 15 ft diameter |
| Sub-canopy | Serviceberry (A. laevis ‘Regent’) | 2 | 8 ft from canopy, E and W | 6-8 ft diameter each |
| Sub-canopy | Elderberry (‘Adams’) | 1 | NW corner | 8 ft diameter |
| Shrub | Black currant (‘Ben Sarek’) | 3 | 4 ft spacing, north edge | 3-4 ft diameter each |
| Shrub | Gooseberry (‘Invicta’) | 2 | 4 ft spacing, partial shade zone | 4 ft diameter each |
| Shrub | Aronia (‘Viking’) | 1 | NE corner | 6 ft diameter |
| Shrub | Hazelnut (C. americana) | 2 | SW corner, 6 ft apart | 8-10 ft diameter each |
| Herbaceous | Comfrey (‘Bocking 14’) | 4 | Around canopy and sub-canopy trees | 3 ft spread each |
| Herbaceous | Yarrow | 6 | Throughout | Self-spreads |
| Herbaceous | Chives | 12 | Under canopy tree drip line | Clumps |
| Ground cover | Strawberry (‘Earliglow’) | 30 | 12 in. spacing | Runner-expands |
| Ground cover | Creeping thyme | 8 | Path edges | Self-spreads |
| Root zone | Garlic | 40 bulbs | Interplanted annually | Harvested July |
| Root zone | Horseradish | 1 | NW edge | Contained |
| Vine | Hardy kiwi (‘Issai’) | 2 | South fence trellis | 15-20 ft spread |
| Vine | Hops | 1 | East fence | 20+ ft/season |
What’s not on this list: Pawpaw was left off because it requires two genetically distinct plants and the additional sub-canopy space competes with elderberry and serviceberry in this footprint. On a 1,500 sq ft or larger plot, add two pawpaws in the east or west expansion zone.

Cumulative 10-year value (mid-range estimates): approximately $9,200 in harvest value.
Input Costs and the Compounding Story
Year 1 is the expensive year. Here’s what a realistic first-year investment looks like for this planting:
| Item | Estimated cost |
|---|---|
| Apple tree (semi-dwarf, bare root) | $35-$55 |
| Serviceberry (2 plants) | $30-$50 |
| Elderberry (1 plant) | $12-$20 |
| Currants (3 plants) | $25-$45 |
| Gooseberry (2 plants) | $18-$30 |
| Aronia (1 plant) | $12-$20 |
| Hazelnut (2 plants) | $20-$35 |
| Comfrey (‘Bocking 14’, 4 root cuttings) | $15-$25 |
| Strawberry (30 bare root) | $20-$35 |
| Creeping thyme (8 plants) | $15-$25 |
| Hardy kiwi (2 plants) | $25-$45 |
| Garlic seed (40 cloves) | $15-$25 |
| Horseradish (1 crown) | $5-$8 |
| Mulch (3-4 cubic yards wood chip) | $0-$60 (often free via Chip Drop or municipal programs) |
| Soaker hose or drip irrigation | $30-$60 |
| Soil amendments (compost, initial fertilization) | $40-$60 |
| Total Year 1 | $317-$598 |
Call it $400 to $450 for a well-sourced installation with some cost discipline.
Year 1 also carries the highest labor load: site prep, planting, mulching the full 1,000 sq ft to 4 to 6 inches depth, irrigation setup, and weed management in the first season while ground cover hasn’t filled in yet. Budget 40 to 60 hours of initial work.
How inputs change over time:
By Year 3, comfrey is established and producing enough biomass for two to three chop-and-drop cycles per season. Each cycle deposits 6 to 12 lb of fresh biomass per plant around the base of adjacent trees. At four comfrey plants, that’s 24 to 48 lb of biomass per cycle - decomposing into the equivalent of a light compost application without purchasing anything.
By Year 5, the leaf canopy from the developing tree and shrub layers begins shading the soil surface. Soil moisture retention improves measurably - Crawford’s research at Agroforestry Research Trust documented a 30% reduction in soil evaporation in established food forest plots compared to open annual beds (Creating a Forest Garden, 2010). Irrigation frequency drops accordingly.
By Year 7 to 8, annual mulch purchases are effectively replaced by leaf fall from the canopy tree (a semi-dwarf apple deposits 15 to 25 lb of dry leaf matter per season), the elderberry, hazelnuts, and serviceberries. Combined with the comfrey system, the soil surface stays covered without purchased mulch. Annual cash input at Year 8 is pruning equipment maintenance and any replacement plants. Budget $50 to $75 per year.
The 10-year input picture:
| Year range | Annual cash input | Annual labor (hrs) |
|---|---|---|
| Year 1 | $317-$598 | 50-70 |
| Years 2-3 | $60-$100 | 20-30 |
| Years 4-5 | $40-$75 | 15-20 |
| Years 6-8 | $30-$60 | 10-15 |
| Years 9-10 | $30-$50 | 6-10 |
10-year total input cost (mid-range): approximately $820.
Against the mid-range yield value of $9,200, the 10-year net is roughly $8,380 from 1,000 square feet - a return ratio of about 11:1 on cash invested. That ratio improves further in Years 11 through 25, when establishment costs are fully amortized and the apple tree is producing 50 to 80 lb per season.

Honest Caveats
You will not have meaningful tree fruit for 5 to 10 years. The apple on M.7 rootstock may produce a handful of fruit in Year 4 or 5. Full production - 40 to 60 lb per season - won’t happen until Year 8 to 10 in most cases. The ROI story in Years 1 through 7 comes from the shrub, herbaceous, and vine layers, not from the canopy. If you need tree fruit sooner, buy it from an orchard and plant a different style of garden.
Zone 4 and colder significantly narrows your options. Pawpaw is borderline. Hardy kiwi (A. arguta) survives to Zone 4 but late frost kills the emerging buds most years in Zone 4 climates - production is unreliable. Serviceberry and elderberry hold up fine, but your canopy options shrink to crabapple and very cold-hardy apple varieties. Hazelnut reliability also drops below Zone 5 without selecting cold-hardy American hazelnut specifically.
Canopy management is the hardest part. The single most common food forest failure is neglecting to prune the canopy tree aggressively enough in Years 3 through 7. A semi-dwarf apple on M.7 left to grow unmanaged will produce a 15 to 20-foot spread within 8 years. The light reaching your currant and gooseberry shrubs drops from 60% to 15% and they decline. Annual dormant-season pruning to maintain an open center or modified leader form is not optional. Budget 2 to 4 hours per year for canopy management starting in Year 2.
This is a multi-decade commitment. The plants described here are not easily moved. The apple tree will outlive your mortgage. Comfrey roots regrow from any fragment left in the soil. Hazelnut clumps expand and persist. Plant a food forest with the understanding that you are changing the permanent character of that 1,000 square feet. If there’s any reasonable chance you’ll want that space for something else in 10 years, a food forest is the wrong choice.
The economics are genuinely compelling and the system does get easier over time. But the first 5 years require consistent attention, the payoff is slow, and the commitment is long. None of that means don’t do it - it means go in with accurate expectations.
