This paper examines the effectiveness of urban farming microinterventions through three design-led case studies in Poland. The cases include "Blooming Structure" (2018, Warsaw), a temporary hydroponic installation; "Micro-cultivation" (2018, Warsaw), a shopfront vertical demonstration farm; and "Micro-cultivation 2" (2019), modular cultivation furniture. The analysis combined project documentation with practice-based observations, applying five interpretive dimensions: spatial fit, technical feasibility, communicative legibility, replicability, and social programming. Findings indicate that successful microinterventions align legible cultivation infrastructure with high visibility, accessibility, and participatory formats that support skills transfer and copying-based scaling. Limitations of this study include the small sample size and its concentration on projects from Poland.

This Wikipedia article covers Robert Hart (1913-2000), a British horticulturist credited as the pioneer of temperate-climate forest gardening. He converted a 0.12-acre (500 sqm) orchard at his Shropshire home into a model forest garden structured in seven layers (canopy, low-tree, shrub, herbaceous, ground-cover, rhizosphere, and vertical/climber). The article also notes he followed a roughly 90% raw vegan diet, citing the Hippocratic maxim to 'let food be thy medicine.'

This Wikipedia article on allotment gardening covers its history and national systems. In the United Kingdom, an 1809 engraving of Birmingham already shows allotment gardens surrounding the town, and the 'Great Somerford Free Gardens' in Wiltshire were founded in 1809; the 1908 Small Holdings and Allotments Act legalized allotments, amended in 1922 and 1950, with plot numbers rising from 244,268 in 1873 to a peak of about 1.5 million in 1918 before declining to roughly 300,000 by 2009. In Germany, 'Schrebergarten' plots trace to the 'Schreber movement' begun in Leipzig in 1864, formalized by the 1919 Small Gardens and Small Leaseholds Land Law; there are now about 1.4 million allotments covering 470 square kilometers, including 833 allotment complexes in Berlin alone. In France, family gardens that emerged in the late 19th century are managed by the 'Fédération Nationale des Jardins Familiaux et Collectifs,' with about 135,000 members. In the Netherlands, the article states the first allotment garden was founded in 1838, there are now 240,000 allotment gardens, and the 'Algemeen Verbond van Volkstuindersverenigingen in Nederland' (AVVN) was founded in 1928.

Homegardens, also known as forest gardens or food forests, are a diverse and sustainable agroforestry model that mimics natural ecosystems by combining trees, shrubs, and other useful plants or small livestock. These systems are gaining popularity in Europe, particularly in Germany, the Netherlands, and Ireland, due to their high productivity and the wide range of benefits they offer on limited space. The FAO defines these systems as agrisilvopasture.

This study investigates the persistence of "gardening by the bloc," an informal urban gardening practice in the green spaces of collective housing districts in post-socialist Bucharest, Romania. Often dismissed in public discourse as a leftover of socialist-era survival strategies, the research instead reconsiders it as an everyday social interaction that supports communities amid urban transformation. Drawing on Tsing and De Angelis, the study frames the practice as a local form of "latent commons" reflecting broader socio-political shifts in a post-socialist city. Based on qualitative research, it documents how residents use, adapt and manage these green spaces and their relations with institutional actors under increasingly neoliberal governance, arguing that the overlap between a market-oriented regulatory project, inherited socialist structures, and collective spatial practices has shaped a distinct way of living together. As an emerging form of urban commons, gardening by the bloc can sustain shared communal practices against an increasingly individualized society and lay groundwork for bottom-up regeneration of housing estates, but the article also reveals contradictions inherent to latent commons, including internal tensions and ambiguities.

Carl Rabitz (1823–1891) was a German master mason and builder. In 1867 he published a pamphlet titled 'Natural Roofs with Volcanic Cement,' promoting greened flat roofs as garden roofs, and exhibited a greened flat roof at the Paris World's Fair the same year. In 1864 he invented a fire-resistant plaster ceiling technique for use under wooden beams, and in 1878 he patented the Rabitz wall (a lath-and-plaster wall construction method).

A study with 44 hobby gardeners in Germany found that substrates are not a major part of gardeners' social interactions, and price is the dominant purchase criterion for substrates, with sustainability not playing an important role. Although basic knowledge about peat is widespread, purchasing substrates is a utility-driven process with mostly passive information behavior.

This paper defines "Vague Farms" as projects in urban vacant spaces that combine urban gardening and local food production with the preservation of informal and spontaneous characteristics of "Terrain Vague." It analyzes five case studies from different European cities to illustrate the emergence of these practices. The study provides a theoretical introduction to Terrain Vague, examines community urban garden projects through the lens of Urban Commons, and proposes a definition of Vague Farms and their characteristics.

This study investigated the link between growing one's own food and dietary quality, using the Healthy Food Diversity Index, Berry-Index, and a produce consumption indicator. It found that growing food at home and in community gardens is associated with the highest fruit and vegetable consumption, while not growing any food is associated with the lowest produce consumption. Overall, the results indicate that growing food is linked to higher dietary quality values, suggesting potential health benefits from home and community gardens. The negative association between not growing food and diet quality highlights a need to promote food-growing programs.

This study tested the effects of feral pigeon guano as a fertilizer on cherry tomato plants in an urban environment on a rooftop in Ivry-sur-Seine, France. In June 2017, 15g of guano was added to 15 cultivation bags, while 15 control bags received only water. After 15 days, guano-treated plants were taller and tended to have more flowers, and the total number and mass of harvested cherry tomatoes were one to two times higher than the control. However, the average mass per fruit was not affected by the treatment. The study concluded that pigeon guano is an efficient local fertilizer for cherry tomato plants in urban areas.
