Square Foot Gardening is a method of intensive gardening where a raised bed is divided into 1-foot squares. Each square holds a different crop, with plant spacing determined by how many plants fit in one square foot (e.g., 1 tomato, 4 lettuce, or 16 radishes). It maximizes yield in small spaces.

Set your bed width and height, then click on any square to pick a plant from the side panel. The grid shows plant icons and the number you should grow per square. Conflicts between neighboring plants are highlighted automatically — hover over the warning icon for details.

Companion planting is the practice of growing certain plants together for mutual benefits like pest control, pollination, and better use of space. For example, tomatoes love basil, while onions stunt bean growth. Our planner warns you about known antagonistic pairs.

We use standard square-foot gardening recommendations: 1 per square for large plants (tomato, pepper), 4 for medium (lettuce, basil), 9 for medium-small (spinach, bush beans), and 16 for small (carrots, radishes). Always check seed packets for variety-specific advice.

The planner checks the four adjacent squares (top, bottom, left, right) for known plant incompatibilities. For example, dill near tomatoes or onions near beans will trigger a warning. These are based on common companion planting research — feel free to experiment!
