A layout companion planting square foot gardening chart is one of the most practical tools for anyone growing vegetables in raised beds or a compact plot. It tells you how many plants fit in each square, which crops grow well beside each other, and which pairings to avoid. Because square foot gardening depends on precise spacing, a good chart saves you from guessing, overcrowding, or losing a whole bed to a poor combination. This guide compares ten chart formats and printable planners so you can pick the one that matches your garden size, your experience level, and how you prefer to plan.
The selection criteria here are based on published specifications, the reputation of the publisher or brand, and patterns that owners and gardeners commonly report. We did not test these products ourselves. We looked at how complete the spacing data is, whether companion and antagonist pairings are clearly listed, how the layout is organized (by crop, by bed, or by season), and whether the chart works for both beginners and experienced growers.

Buying Guide
Selection criteria
When comparing charts, start with whether the spacing system matches your beds. A square foot chart is built around 1-foot squares, so it fits raised beds and grid layouts. Row-planting gardeners need a different reference. Next, check whether companion and antagonist pairings are listed clearly. Finally, consider how you will use the chart: at the bed edge, on a wall, or at a desk for planning.
Important features
- Grid accuracy: Plant counts per square should match the crop’s mature size.
- Companion pairings: Look for both helpful pairs and pairs to keep apart.
- Durability: Laminated or coated surfaces hold up better in the garden than plain paper.
- Printability: Printable charts let you reprint or adjust for new beds.
- Record space: Planners and journals help track what worked.
Specs to check
- Bed size the chart assumes (commonly 4 by 4 feet)
- Number of crops covered
- Whether spacing is per square, per row, or per plant
- Format: book, wall chart, card, wheel, notebook, or printable
Choosing by need
- New to the method: A full book or a wall chart with clear spacing counts.
- Setting up beds: A grid template kit plus a spacing reference.
- Quick checks while planting: A laminated companion card.
- Season-by-season planning: A planner notebook or printable chart.
- Visual learning: A companion wheel.
Things to watch out for

- Companion claims vary in strength. Treat them as practical guidance, not guaranteed results.
- Paper charts need protection from moisture if used outdoors.

FAQ
What is a layout companion planting square foot gardening chart?
It is a reference that shows how many plants of each crop fit in a 1-foot square and which vegetables grow well or poorly next to each other. It combines spacing guidance from the square foot method with companion planting notes.
How many plants fit in one square foot?
It depends on the crop. Large plants like tomatoes or squash often take a full square, while small crops like carrots, radishes, or lettuce can fit 4 to 16 per square. Always check the chart for the specific vegetable.
Do companion planting charts really work?
Some pairings have documented benefits, such as basil near tomatoes for pest deterrence or beans fixing nitrogen for nearby plants. Others are more traditional than proven. Use charts as a planning aid and observe your own results.
Can I use a square foot chart for in-ground beds?
Yes, as long as you mark the bed into 1-foot squares. The spacing logic works in any grid layout, including in-ground rows set out in squares.
Should I plant every square at once?
Not necessarily. Many gardeners plant some squares in spring and others in later months, using the chart to plan succession sowing. Check the planting window for each crop before filling a square.
What size bed does a square foot chart assume?
Most charts assume a 4-by-4-foot bed, which gives sixteen 1-foot squares. Some also show layouts for 4-by-8-foot or other sizes. Confirm the bed size the chart is built for before you plant.
Is a printed chart better than a phone app?
Printed charts stay visible in the garden without battery or signal and are easy to mark up. Apps can be easier to update. Many gardeners use both, with a printed reference at the bed and digital records at home.
Conclusion
A layout companion planting square foot gardening chart is most useful when it matches your bed format and helps you plan both spacing and pairings. For beginners learning the method, a full book or a clear wall chart gives the most complete guidance. Gardeners who need a quick reminder at the bed edge will get the most from a laminated companion card. Season planners and journals suit anyone who rotates crops and wants records. Visual learners may prefer a companion wheel, while builders setting up new beds will benefit from a grid template kit. Choose the format that fits how you work, check the spacing data against your bed size, and adjust for your local climate and planting dates.
