A garden bed grid planner helps you visualize plant placement before digging. By arranging plants on a grid, you can optimize spacing, plan companion planting, and ensure each plant gets adequate sunlight. It's especially useful for square-foot gardening, raised beds, and small-space vegetable gardens.
Desktop: Simply drag any plant from the left palette onto a grid cell. You can also drag plants between cells to rearrange them. Click the Γ on any occupied cell to remove a plant. Mobile: Tap a plant card to select it (it will highlight), then tap any grid cell to place it. Tap the Γ to remove.
Companion planting is the practice of growing certain plants together for mutual benefit. For example, basil planted near tomatoes can improve flavor and repel pests. Marigolds deter nematodes and attract pollinators. Our planner lets you experiment with different arrangements to find the best companions for your garden.
Each grid cell typically represents 1 square foot (30Γ30 cm) in square-foot gardening. A tomato plant may need 1β4 squares depending on the variety, while lettuce can fit 4 plants per square. Adjust your grid size to match your actual garden bed dimensions and plant spacing requirements.
βοΈ Full Sun β Needs 6+ hours of direct sunlight daily (tomatoes, peppers, sunflowers). β Partial Sun β Thrives with 3β6 hours of sun (lettuce, some herbs). π Shade Tolerant β Can grow with less than 3 hours of direct sun. Always consider your garden's sun exposure when placing plants.
