Bed Layout Helper

Enter your bed's dimensions and the crops you want to grow, and this tool arranges them into a square-foot-method grid automatically, placing beneficial companions near each other and keeping known antagonist pairs apart - the same layout planning described conceptually on Square-Foot Gardening, done for your specific bed and crop list rather than left to manual trial and error.

How the Grid Is Built

The tool first converts your bed's length and width into a whole-number grid of one-foot squares, then works out how many plants of each selected crop fit per square using that crop's own recommended spacing from the shared crop dataset - a 12-inch-spacing crop gets one plant per square, a 4-inch-spacing crop gets nine. Once the plant counts are set, the tool arranges crops across the grid using the same companion and antagonist relationships covered in the Companions section, rather than placing them randomly or alphabetically.

What "Automatically Honoring" Relationships Actually Means

When two of your selected crops have a documented beneficial relationship, the tool positions their squares adjacent to each other where the grid geometry allows; when two crops are flagged as antagonists, it actively keeps their squares apart rather than leaving the arrangement to chance. Crops with no documented relationship to each other are placed based on remaining space and don't drive the arrangement one way or another - an unrated pairing isn't a red flag, it's simply not a factor either tool or page treats as significant.

When the Grid Can't Satisfy Everything

A crowded crop list with several antagonist pairs and a small bed can genuinely run out of room to keep every conflicting pair separated - when that happens, the tool flags the specific squares where a compromise was necessary rather than silently producing a layout that looks clean but quietly ignores a known antagonist relationship. Reviewing those flagged squares and deciding whether to swap a crop, split it across two seasons, or accept the trade-off is a judgment call the tool surfaces rather than makes for you.

Large Sprawling Crops Need a Separate Plan

Winter squash, pumpkins, and other crops whose real footprint spans multiple square feet don't fit the standard one-square-per-plant logic, the same limitation described on Square-Foot Gardening itself - the tool flags these crops rather than force-fitting them into a single square, and suggests either a vertical trellis (see Vertical Gardening) or a dedicated bed outside the grid for anything that genuinely needs more room than the grid method assumes.

Saving and Sharing a Layout

Like the Planting Calendar Generator, a completed layout is encoded into the page URL rather than saved to an account, so bookmarking or sharing the link reproduces the exact same grid arrangement later or for someone else - genuinely useful for comparing a couple of different crop-list options side by side before committing to one for the season.

A Worked Example

A 4x4-foot bed with tomatoes, basil, and fennel added: the tool places basil in a square adjacent to tomatoes, since the two are a documented beneficial pairing, and puts fennel's square as far from tomatoes as the 16-square grid allows, flagging the pairing as a known antagonist relationship due to fennel's root exudates suppressing nearby plant growth - the same relationship explained in more depth on that specific companion-pair page.
