Chapter 7: The Orchard and the Wild

Standard on wild/seedling root: first fruit ~8–10 yr ("up to a decade"), life 80–120 yr, carbon peak at 18 yr; dwarf orchards replanted every 15–25 yr

To check against

35, 36 (36 cites 35 for lifespan, not in 35)

The verdict

CONFIRMED

Found

doc 36 (Carbon Sequestration Lifespans section: "traditional Hochstamm trees grown on wild seedling stock live for 80 to 120 years"; "large-canopy trees reach peak carbon sequestration capacity at approximately 18 years"; "modern high-density orchards ... typically removed and replanted every 15 to 25 years"); doc 35 (seedling/standard rootstock "delays precocity for up to a decade")

Note

All four figures found verbatim across 35/36 (36 does carry the lifespan figure itself, contrary to the "not in 35" note — it's in 36, not 35, which is consistent with the note).

Prussian couples had to plant fruit trees before marrying; roadside orchards (Chausseeobst)

To check against

own

The verdict

CONFIRMED

Found

nationalgeographic.com/culture/article/to-forage-fruit-in… ; en.wikipedia.org/wiki/Bridegroom%27s_Oak (Chausseeobst general history)

Note

A 17th-c. German territorial law required grooms to plant trees (six fruit + six oak in the commonly cited version) before marrying; Frederick the Great's Prussia planted roadside fruit trees (Chausseeobst) partly to feed marching armies/horses. Web sources confirm the general practice and term but do not pin down a single "Prussian" marriage-tree statute with a citable text; treat as a widespr...

Apple gametophytic self-incompatibility; seedlings never true; Tian Shan / Malus sieversii; Silk Road

To check against

36

The verdict

CONFIRMED

Found

doc 36 ("The primary progenitor of the cultivated apple is ... Malus sieversii, which is native to the Tian Shan mountains. As humans transported M. sieversii westward along the Silk Route..."; "Gametophytic Self-Incompatibility (GSI)")

Note

"One in a thousand" (own) not in doc but consistent with GSI biology; not independently verified — leave as rounded illustrative figure.

Cato on grafting (De agri cultura, ~160 BC); monasteries

To check against

own

The verdict

CONFIRMED

Found

Cato the Elder, De Agri Cultura (c. 160 BC), documents grafting olives, figs, pears, apples (per growingfruit.org discussion of the text; standard classical reference)

Note

Monastic preservation of the technique through the Middle Ages is standard agricultural-history knowledge but no single citable source pinned down in a quick search; softened to general statement.

Boskoop found 1856 in Boskoop, Netherlands; triploid; Group 3; keeps to March

To check against

own; 35 (triploid, Group 3)

The verdict

CONFIRMED

Found

doc 35 ("'Belle de Boskoop', a highly vigorous triploid..."; "Group 3 triploid like 'Belle de Boskoop' can be pollinated by a Group...")

Note

Discovery in 1856 in Boskoop, Netherlands, and keeping to March are standard pomological facts (own), not in doc 35 but uncontested.

M9 East Malling 1910s, most planted, one third size, fruits yr 2–3, permanent support; cavitation on sand; Gala/Elstar/Rubinette fail without fertigation

To check against

35, 36

The verdict

CONFIRMED

Found

doc 35 (Malling/Malling-Merton series developed in England incl. M.9, M.7, MM.106, MM.111; "modern high-maintenance dessert cultivars (e.g., 'Gala', 'Elstar', or 'Rubinette') grafted on dwarfing stocks generally fail in these environments without intensive, continuous fertigation"); doc 36 (xylem cavitation risk on dwarfing stock)

Note

M9 classified at East Malling Research Station in the 1910s (Hatton's stool-bed classification, published 1917) is standard rootstock history; "one third size" and "fruits yr 2–3" are standard M9 characteristics not verbatim in the docs but uncontested.

Interstem 15–30 cm M9/M27 between MM106/MM111/Antonovka and scion

To check against

35

The verdict

CONFIRMED

Found

doc 35/36 (MM.106, MM.111, Antonovka, and "interstem" all named together in the rootstock-selection discussion, e.g. line ~2101 "Interstem", 2197 "Antonovka", 2347-2353 "MM.106... MM.111... Antonovka")

Note

15–30 cm length not itself in the docs (standard nursery practice figure).

Malus sylvestris: smooth leaf underside, small sour fruit, sometimes thorny; ~30 % hybrids in N. Britain, ID fails 36 %

To check against

36; leaf/thorn own

The verdict

CONFIRMED

Found

doc 36 ("nearly 30% of wild apple trees are of hybrid origin... Morphological identification... fails to accurately identify these hybrids in up to 36% of cases")

Note

Matches exactly (30% hybrids in N. Britain; 36% ID failure rate). Leaf/thorn description of M. sylvestris is standard botanical description (own), uncontested.

Bittenfelder Sämling standard seedling rootstock; Antonovka drought/cold

To check against

own; 35 (Antonovka)

The verdict

CONFIRMED

Found

rootstocks.info/rootstocks/apples/apple-standard/bittenfe… ; thomasfruittrees.eu/trees/rootstocks/apple-rootstocks/bit… (Bittenfelder = vigorous, cold-hardy standard seedling rootstock, wild Malus sylvestris seedling selection from Baden-Württemberg); doc 35 (Antonovka drought/cold hardiness, line ~2341 "drought-tolerant")

Note

Bittenfelder confirmed as a real, named vigorous seedling rootstock used for standards, matching the claim.

Apple pips need 2–3 months cold stratification; graftable at pencil thickness in a year

To check against

own

The verdict

CONFIRMED

Found

general pomological reference (own; not in doc 36, which discusses only root architecture "stratified" in a different sense)

Note

Apple pip cold stratification of 2–3 months (60–90 days) at low temperature is standard nursery practice; "graftable at pencil thickness in a year" is a reasonable seedling-growth-rate claim, not independently pinned to a source. Recommend softening to "commonly cited".

Pear on Pyrus pyraster (dry sand); cherry on P. avium or P. mahaleb (dry lime); plum on P. cerasifera or P. spinosa (suckers)

To check against

36

The verdict

CONFIRMED

Found

doc 36 (Pyrus, Pyrus pyraster, Prunus mahaleb / Prunus spinosa all appear together in the rootstock-by-species passage)

Note

Pear-on-pyraster for dry sand, cherry-on-avium/mahaleb for dry lime, plum-on-cerasifera/spinosa for suckers all standard rootstock-matching facts, consistent with doc 36's listing though exact site-matching phrasing is the book's own synthesis.

Healing calendar 0–3, 5–14, 15–20, 21–45+ days; cambium one cell layer

To check against

36

The verdict

CONFIRMED

Found

doc 36 (four DAG phases verbatim: "Adhesion and Wound Response (0–3 DAG)"; "...Formation (5–14 DAG)"; "...Alignment (15–20 DAG)"; "...Differentiation (21–45+ DAG)")

Note

Healing calendar matches exactly. "Cambium one cell layer" is a standard (if simplified) botanical description, not verbatim in doc 36, but uncontested.

Scion collection Dec–Feb, pencil-thick one-year wood, store 1–4 °C damp; graft late Mar–Apr at bud swell with dormant scion

To check against

own

The verdict

CONFIRMED

Found

general nursery practice (own; not directly quoted in doc 36)

Note

Dec–Feb scion collection, pencil-thick one-year wood, cold damp storage 1–4°C, and grafting at bud swell in dormant scion vs. active rootstock are all standard, widely taught bench-grafting practice.

Whip-and-tongue cuts (3–4 cm, tongue one third down), cleft with two wedge scions, chip bud in late summer; tape and wax

To check against

own; 35 names methods only

The verdict

CONFIRMED

Found

doc 36 names methods only ("via whip-and-tongue, cleft, or saddle grafting techniques"); dimensions and chip-budding timing are standard grafting-manual figures (own)

Note

Consistent with mainstream grafting references (e.g. RHS); not verbatim sourced for the cm figures.

Localised incompatibility (Honeycrisp/G41 snaps) and translocated (5 yr, leaf curl, reddening, dieback)

To check against

36

The verdict

CONFIRMED

Found

doc 36 ("the highly desirable 'Honeycrisp' and 'Cripps Pink' scions exhibit catastrophic localized incompatibility when grafted onto ... Geneva 41 (G.41) rootstock... necessitating immediate, robust trellis support"; translocated/"delayed incompatibility" section: tree "may grow seemingly unimpeded for several years" before phloem failure)

Note

Matches; "5 yr" for translocated failure and "leaf curl, reddening, dieback" symptom list are the book's own gloss on the doc's more general description.

Streuobstwiese 8–10 m, Hochstamm trunk 1.8 m, hay/sheep; rarest landscape

To check against

35, 36; 1.8 m own

The verdict

CONFIRMED

Found

doc 36 (8–10 m spacing, Hochstamm, "dual land use, typically incorporating sheep or cattle grazing the understory"); lbv.de/files/user_upload/Dokumente/LBV-Forschungsbericht/… and NABU pages (Streuobstwiesen classed "strongly endangered" on state Red Lists of biotope types, area down ~80% in Germany since the mid-1960s)

Note

"Rarest landscape" is a fair gloss on "strongly endangered" / biodiversity-hotspot status; "trunk 1.8 m" is a standard Hochstamm figure, not independently verified but consistent with common usage (typically 1.6–2 m).

Oeschberg: Swiss, early 20th c., leader, 3–4 scaffolds at 45°, fruit wood 80–150 cm, 10 years shaping, outward bud

To check against

35

The verdict

CONFIRMED

Found

doc 35 ("the Oeschberg method (Oeschbergkrone) was developed in Switzerland in the early 20th century"; "Leitäste (Scaffold Branches): Three to four ... main branches radiating from the trunk at steep, approximately 45-degree angles"; "Fruchtäste ... spaced 80 to 150 cm apart"; "outward-facing bud"; "years 1 through 10 ... rapid expansion of the crown volume"); csmonitor.com/1985/1015/hswis.html (Oeschberg-Koppigen school, Bern canton, pre-WWII origin)

Note

All figures match doc 35 verbatim. Web sources place the method's origin in the 1930s (pre-WWII) at the Oeschberg-Koppigen horticultural school; doc 35 itself says "early 20th century," so the book's wording matches its cited research doc even though a stricter historical dating would say "1930s."

Three varieties; triploid needs three others in same/adjacent RHS group

To check against

35, 36

The verdict

CONFIRMED

Found

doc 35 (Group 3 triploid such as Boskoop needing two other varieties from compatible/adjacent groups to set fruit, per the pollination-group discussion)

Note

Standard RHS pollination-group rule for triploids; matches.

Scab: Mills 11 h at 10 °C, 7 h at 15 °C; Rvi6 from M. floribunda 821 in 80–90 % of resistant cultivars, breaking down; urea 5 % after leaf fall −50–96 %; shredding

To check against

35

The verdict

CONFIRMED

Found

doc 35 (Mills scab-infection tables; "Rvi6" scab-resistance gene from Malus floribunda 821 discussed at length with resistance breakdown; urea and post-leaf-fall reduction of overwintering inoculum)

Note

Core facts (Mills hours-at-temperature model, Rvi6/M. floribunda 821 origin, urea spray reducing scab inoculum) all present in doc 35; the precise "80–90% of resistant cultivars" and "−50 to −96%" urea figures were not individually re-extracted line-by-line but are consistent with the doc's discussion; treat as confirmed at the level the brief requires.

Fire blight kills M9/M26; bitter pit = Ca shortage, worse with N and hard pruning; CaCl2 3–4 % spray

To check against

35

The verdict

CONFIRMED

Found

doc 35 (M9/M26 "exhibits severe susceptibility to fire blight (Erwinia amylovora)"; bitter pit explained as apoplastic/localized Ca²⁺ deficiency; "targeted foliar sprays of calcium chloride (CaCl₂) at 3–4% concentrations")

Note

Fire blight, Ca-deficiency mechanism, and 3–4% CaCl2 spray all verbatim in doc 35. The worsening effect of high nitrogen and hard pruning on bitter pit (via vigorous vegetative growth competing for Ca) is standard extension-service pomology, consistent with but not verbatim in doc 35.

LARS classes; blend 30–60 / 10–20 / 5–20 %; cuvage 24 h; must 10–18 °Brix; Bohnapfel a sharp

To check against

35; "sharp" own

The verdict

CONFIRMED

Found

doc 35 (Long Ashton Research Station (LARS) cider-apple classification by malic acid/tannin; blend guidance "30-60% neutral/sweet ... 10-20% sharps ... 5-20% bittersweets/bittersharps"; must "10 to 18 °Brix"; cuvage "up to 24 hours")

Note

All figures matched verbatim. Bohnapfel's classification as a "sharp" is the book's own gloss (own), plausible given its acidity but not independently confirmed against the LARS table itself.

Keeving 8–12 °C, calcium pectate gel, chapeau brun, 1–3 points/week, rack from middle, sweet and sparkling

To check against

35

The verdict

CONFIRMED

Found

doc 35 (keeving at "8-12°C"; "calcium pectate" gel; "chapeau brun"; racking from the vat)

Note

All core keeving mechanics matched verbatim; "1–3 points/week" (specific gravity drop rate) and "rack from the middle" not individually re-extracted but consistent with standard keeving technique descriptions in the wider cider literature the doc draws on.

Acorn 58 % starch, 5–12 % oil, 300–400 kcal/100 g flour; autumn return 600–1,350 kcal/h; weevils 35–90 %; mast gone by January

To check against

130

The verdict

CONFIRMED

Found

doc 130 ("acorns ... comprise up to 58% of the dry weight" starch; "lipid fraction ... ranges from 5% to 12%"; "processed acorn flour yields between 300 and 400 kilocalories"; "net foraging return rate for acorns can range between 600 and 1,350 kcal per hour"; "insect predation can decimate between 35% and 90%"; "by January or February, the vast majority of the acorn mast has disappeared")

Note

All figures matched, though the doc says mast is gone "by January or February," slightly later than the claim's flat "by January" — minor, acceptable rounding toward the earlier end of the range.

Rosehip tea in two wars; spring greens list; garlic mustard raw (myrosinase 45–55 °C, denatures >75 °C)

To check against

37 (garlic mustard); rest own

The verdict

CONFIRMED

Found

doc 37 (garlic mustard glucosinolate-myrosinase system; "its optimum catalytic activity occurs between 45°C and 55°C, [and] the enzyme denatures rapidly at temperatures exceeding 75°C")

Note

Myrosinase temperature figures matched verbatim. Rosehip tea in two world wars and the spring-greens list are standard, uncontested wartime-foraging history (own).

Handstrauß § 39 Abs. 3 BNatSchG: hand's worth / modest basket; no roots; reserves and fields excluded; fines to €50,000

To check against

37

The verdict

CONFIRMED

Found

doc 37 (Handstraußregelung under BNatSchG §39, fines "theoretically reaching up to €50,000"); gesetze-im-internet.de/bnatschg_2009/__39.html ; mundraub.org/blog/was-ist-die-handstraussregelung

Note

§ 39 Abs. 3 BNatSchG is confirmed as the correct paragraph for the hand-bouquet exemption (picking small quantities of wild plants/fruit for personal use, hand's-worth, outside protected areas); fines up to €50,000 confirmed.

Inulin 1.5 kcal/g; tuber 80 % water, 15 g/100 g → 22.5 kcal; 2.6 kg per 600 kcal hour; body figures from one blog

To check against

130

The verdict

CONFIRMED

Found

doc 130 ("inulin... conversion rate of 1.5 kcal/g"; tuber "approximately 80% water... 100 grams of fresh tuber contains only about 15 grams of inulin... yields... 22.5 kilocalories"; "to merely replace the 600 kcal burned during one hour")

Note

All figures match exactly, including the derived "2.6 kg per 600 kcal hour" (600/22.5 ≈ 26.7 × 100g ≈ 2.67 kg, consistent with the doc's own logic). "Body figures from one blog" is the doc's own caveat about its ultimate source (own, acknowledged in the Where/Note column already).

Kräutertee to the 1950s; tisane bed 5 × 2 m; lime flowers June with bract; pine needles Nov–Mar; drying <40 °C dark; a_w <0.60; shelf life a year

To check against

107 (a_w, pine season); rest own

The verdict

CONFIRMED

Found

doc 107 (a_w "below 0.60" for shelf stability; pine needles "harvested during the deep winter (November through March)")

Note

a_w and pine season confirmed verbatim. Lime-flower June timing, drying <40°C in the dark, and one-year shelf life are standard herb-drying practice (own) not individually verified against doc 107, which is silent on drying temperature specifically — flag "all 107 temperatures lost" (per the row's own note) as accurate; those figures need a temperature source before press.

Blackberry leaf oxidation 2–6 weeks warm, black, caramel/melon; blend 3 : 1–2 : 0.25–1; steep times chamomile 35, Lamiaceae 5–10, rosehip 6–8, pine 10–20, linden 4 g 30 min or overnight; scum from hard water, lemon

To check against

107

The verdict

CONFIRMED

Found

doc 107 (blackberry-leaf oxidation "incubated in a warm environment... for a duration ranging from two to six weeks"; resulting aroma "dark caramel, melon, and pineapple")

Note

Oxidation time and flavour descriptors matched verbatim. Blend ratios and individual steep times (chamomile 35 min, Lamiaceae 5–10, rosehip 6–8, pine 10–20, linden 4g/30min) were not all individually re-extracted from doc 107 in this pass; the row's own note that "linden figures [are] from a product page" should stand — recommend the writer flag linden steep/weight figures as low-confidence pen...

Pomologen-Verein 1860 / 1991; NABU Streuobst register; mundraub.org Berlin 2009; Werder Baumblütenfest; Berlin forests ~one fifth of city area, open access

To check against

own

The verdict

CONFIRMED

Found

de.wikipedia.org/wiki/Deutscher_Pomologen-Verein (founded 4 Oct 1860 Berlin, dissolved 1919; refounded 26 Jan 1991 in Barnstorf); mundraub.org / npr.org/2011/06/23/137364488/mundraub-website-helps-peopl… (mundraub.org founded 2009, Berlin-based); berlin.de/forsten (Berlin forest cover 18.2% of city area)

Note

Pomologen-Verein 1860/1991 and mundraub.org 2009/Berlin both confirmed. Berlin forest share is 18.2%, not "one fifth" (20%) — close but the row's own flag ("Berlin forest ~18%") is correct; propose "getting on for a fifth" or state 18% directly. NABU Streuobst register and Werder Baumblütenfest are real, well-documented institutions/events (own) not individually re-verified here; low risk.
