Garden plot

A garden plot is a constructible item added to Fallout 4 by the Wasteland Workshop add-on.

Characteristics
The garden plot, accessed through the resources/miscellaneous menu in the workshop, is a type of world object that the Wasteland Workshop add-on permits the Sole Survivor to construct in most settlements using the workshop's resources/materials menu. Once placed, plants function in the garden plots in exactly the same way as in natural ground.

The garden plot may be used to supplement the food supplies of settlements with unsuitable terrain.

There are a few potential settlements — e.g., the Boston Airport, Home Plate and the Mechanist's lair in which all of the workshop's planting functions are deliberately disabled. In general, garden plots aren't a work around to support much larger settlement populations than the game designers intended for those particular settlements, but they may be useful in improving effectiveness of farming in many other settlements.

Garden plots also have other potential benefits — even in settlements with ample natural dirt already available:

Each garden plot's outlines — which are visually modeled after partially buried landscaping timbers — provide a clear and obvious visual demarcation of its boundaries, even if multiple garden plots are placed as closely as possible side-by-side. (They do not snap together, or to any other world items, so each garden plot must be manually placed on its own.) Each is a square slightly smaller than a shack foundation floor, so each requires a fairly large area of unobstructed horizontal space for initial placement. Larger plants (like razorgrain) may require moderately patient rotating, jiggling and experimentation in order for all four plants to fit together in one garden plot. Nevertheless, even if the garden plots are placed closely side-by-side, and even if the above-ground foliage from their plants partially overlaps with others in the same or adjacent garden plots (as typically happens with closely-spaced mutfruit), it is still obvious at a glance which individual plants are in which garden plot.

Garden plots can help the Sole Survivor organize and keep better visual track of how many plants, and where, and of what types, each settlement has at any given time. Likewise, as compared especially to plants placed on terrain with only limited and irregular spots of natural dirt, one may or may not be able to achieve a higher plant density per square-foot. But regardless, garden plots make it relatively easier to check for (typically exactly) four healthy plants in each garden plot: simply by sorting the plants into obvious groups of four, it's easier to spot at a glance, for example, which (if any) plants have been damaged by a raid. Likewise, when manually harvesting, the visual organization imposed by the plots' boundaries will permit faster and more thorough collection by the Sole Survivor. Although most other objects can block placement of a garden plot, one can place the garden plot over already-planted and existing plants without having to store or move them first, and once a garden plot has been planted, it can be picked up and moved together with its plants, which permits construction and reorganization/movement of the Sole Survivor's agricultural areas in a more efficient fashion.

Garden plots may be placed on fairly rough, angled, or uneven terrain, so long as the ground space isn't obstructed by other world objects. But they are not limited to placement on natural, unimproved terrain. Rather, garden plots may also be placed upon many other places, including settler-accessible rooftops, or inside greenhouses or similar enclosed, elevated and roofed structures — which may make their crops relatively more defensible than crops planted in natural dirt. One doesn't need "grow lights," continuing applications of fertilizer (although it's an initial construction component) or other special equipment for garden plots to work as well indoors as out. If placed immediately on top of natural ground that would have otherwise supported a water pump or powered water pump, those will function normally (although it would be a waste of the garden plot); if on top of a roof or other structure already above ground, however, the potting soil of the garden plot can't be drilled through to strike water and the pumps can't be placed.

In addition to their economic function, garden plots can be used for landscaping purposes, adding a vivid green element to recreational areas (roofs and large balconies) as well as dividing up large spaces without walls. Mutfruit trees are optimal for the former usage and razorgrain for the latter.
