Mexico City’s chinampas are a canal-linked wetland farming system; the Three Sisters is a companion-planting tradition involving maize, beans, and squash. Neither is a universal blueprint, but both show why successful gardening begins with local conditions—and how some broad principles can inform a home garden.
What gardening techniques are used around the world?
There is no single global method. A technique makes sense in the conditions that shaped it: the landform and drainage, available water, growing season, crops and local varieties, soil-building materials, and the labor a community can sustain. Two well-documented examples illustrate different responses to those conditions.
Chinampas: farming with canals in Mexico City
Chinampas are small raised plots formed from lake-bottom sediments, branches, and decaying vegetation, arranged among canals and ditches. The Food and Agriculture Organization (FAO) describes construction using stakes and a sturdy perimeter, with layers of soil, organic matter, and sludge added to form the plots. The canals support irrigation and transport, while cultivation includes multiple crops, crop shifts, and agroforestry. This is a living agricultural system shaped by local wetland hydrology and urban food needs—not simply a set of floating gardens. FAO’s GIAHS profile of the chinampa system reports 51 domesticated plant species and 96 non-domesticated species, including plants used for fodder, medicine, and food. The profile does not date those counts, so they should not be read as a current census.
Three Sisters: maize, beans, and squash grown together
In the practice described by the Royal Botanic Gardens, Kew, maize, beans, and squash are planted together in small mounds, with squash between the mounds. Maize provides a structure for climbing beans. Kew attributes the practice to Indigenous peoples in North America and describes the plants as supporting one another. Eddie Johnston’s Kew article puts the wider history this way: “Several groups of indigenous peoples in North America have been making use of companion planting to maximise their crop growth since the dawn of plant domestication.” This example is a specific tradition, not evidence that every commonly suggested companion-plant pairing is effective. Read Kew’s account of companion planting.

What these methods respond to
The examples are better understood by the conditions they address than by ranking one culture’s approach against another. Chinampas depend on a particular wetland and canal setting; Three Sisters coordinates three crops in a shared planting arrangement. Their origins and scale differ, and the available sources do not provide comparable yield figures.
| Consideration | Chinampas | Three Sisters |
|---|---|---|
| Landform and water | Raised plots within a network of canals and ditches; canals support irrigation and transport. | Small planting mounds, with squash planted between them; the cited Kew account does not specify a water-management system. |
| Crops and planting | Multiple crops, crop shifts, and agroforestry; FAO’s profile describes 51 domesticated and 96 non-domesticated plant species, with no publication year stated for these counts. | Maize, beans, and squash grown together; maize supports climbing beans. |
| Soil and fertility | Plot construction layers include soil, organic matter, and sludge; FAO describes organic matter inputs to maintain fertility. | The cited Kew account describes planting arrangement and mutual support, but does not detail soil-building practices. |
| Fit for an ordinary home garden | Not a direct backyard template: the system is tied to local wetland hydrology, canals, and its surrounding agricultural context. | May inspire a locally adapted multi-crop planting, if suitable varieties, space, and season allow. |
How can you adapt these ideas to a home garden?
Adapt the underlying decisions—how to build soil, manage water, choose plants, and organize beds—rather than trying to reproduce a whole agricultural heritage system. FAO guidance offers a range of possible practices, including compost, mulch, crop rotation, raised beds, local varieties, rainwater harvesting, and drip irrigation. Which options make sense depends on the site and gardener; they are not a universal recipe. FAO’s garden guidance and its school-garden guide describe these approaches.

Choose a growing setup that suits the site
Use in-ground beds or raised beds according to site conditions and personal needs; raised beds are an option, not a requirement. Consider drainage, available space, access to water, and the effort needed to maintain the setup. A raised bed is not a chinampa: the latter is part of a canal-linked wetland system.
Build soil and manage water locally
Where appropriate, compost and mulch can contribute organic matter and help manage the soil surface. Rainwater harvesting or drip irrigation may suit some sites, but feasibility depends on local rainfall, water access, rules, and garden layout. FAO lists these as practical options, not as methods that work equally well everywhere.

Rotate crops and be careful with companion-planting claims
FAO recommends rotating crop families between beds to help reduce disease and support yields. Keep a simple record of what grew where, then shift related crops to another bed in a later planting cycle when space allows. For companion planting, the Three Sisters is a documented example; it does not establish that every popular pairing produces a benefit. Select plants based on local growing conditions and reliable guidance for the specific crops.
Follow local calendars and choose suitable varieties
Planting dates and crop choices cannot be made universal in a global guide. The University of New Hampshire Extension recommends using a local planting schedule as a starting point; site, climate, and season should guide the final choices. Consult UNH Extension’s getting-started guidance and local extension or gardening resources for timing and varieties suited to your area.

What should you take away?
Global gardening techniques are responses to particular environments and needs, not kits to copy unchanged. Chinampas show how farming can be organized around wetland hydrology; Three Sisters shows a specific way of growing three crops together. For a home garden, translate carefully: select locally suitable plants, work with the site’s water and soil, rotate crops where feasible, and treat raised beds and companion planting as choices rather than rules.
