The regenerative urban garden I: No-till gardening

No-till and sheet mulching approaches

  • Several commenters favor a hybrid strategy: initially till to remove buried debris, then switch to no-till with cardboard and deep mulch.
  • Sheet mulching (cardboard/newspaper + wood chips over existing vegetation) is praised for suppressing Bermuda grass, ivy, and other invasives, and for boosting fertility compared to tilling first.
  • Others prefer mulched raised beds or hugelkultur-style beds for easier maintenance and self-composting.

Cardboard, newspaper, and contamination concerns

  • Repeated worries about inks, coatings, PFAS, and other toxins in cardboard/newspapers, especially for food gardening.
  • Counterpoints: modern newsprint and many inks are claimed to be soy-based and relatively safe; rule of thumb is to avoid glossy and heavily printed materials.
  • Some link to sources arguing cardboard should not be used on soil; others cite work suggesting limited toxicity and note fungi can sequester heavy metals, though that material then must be removed.

Composting practices and tools

  • Strong enthusiasm for composting as satisfying and foundational for regenerative gardening.
  • Techniques discussed: cold piles, hot piles, worm bins, tumblers, static insulated bins, bokashi pre-fermentation, weed teas, and simply piling organic matter on soil.
  • Trade-offs: tumblers can be less biologically rich (fewer worms) and sometimes stall; open piles are easier and very effective if connected to the ground.
  • Odor, rats, and neighbor concerns are mitigated with enough carbon cover and proper moisture; some avoid food scraps in open piles, others are comfortable with careful management.

Urban gardening safety and pollution

  • One camp is strongly skeptical of urban food gardening and chickens, citing likely contaminated soils and evidence of high PFAS/lead in backyard eggs in some regions.
  • Others argue contamination varies by location, can be mitigated (e.g., straw bale growing, remediation strategies), and that industrial food systems are also polluted (microplastics, tire additives).
  • Container gardening and imported soils are suggested, but even commercial “organic” soil is reported to contain debris, be hydrophobic, or potentially contaminated via post-consumer compost streams.

Tilling vs aeration and soil health

  • Debate over whether no-till actually reduces labor and whether heavily compacted soils still need initial tilling.
  • Some stress that tillage harms soil structure, biology, and increases compaction over time; the goal is to build a self-sustaining soil ecosystem.
  • Others note that in practice, gardeners often “aerate” with a broadfork; there is a long subthread arguing whether this counts as tillage or not (semantics vs practical distinctions).
  • Large-scale farmers are cited on both sides: some remain conventional till; others have adopted no-till at scale.

Carbon sequestration and engineered solutions

  • No-till is highlighted as a plausible method for increasing soil carbon, with the idea that small annual gains in topsoil depth could offset atmospheric CO₂ increases.
  • Commenters mention biochar, algal blooms, and high-biomass systems as potential engineered or semi-engineered carbon sinks, though feasibility and risks are not deeply explored.

Starting small, yields, and economics

  • Advice to avoid doing everything at once: build compost capacity, start with a few beds, learn pest pressure, and add infrastructure (fencing, netting, greenhouse) gradually.
  • Lists of beginner-friendly vegetables and pest-protection tips (e.g., netting brassicas) are shared.
  • Consensus that home gardening is rarely cost-competitive with commercial agriculture; its value is in taste, control over methods, aesthetics, and personal satisfaction.
  • Views on no-till range from curiosity to strong endorsement; one suggestion is to test it on a small plot and judge by experience rather than promises of “incredible” yields.
