Planting summary
Soil mix volumes
Spacing values are practical starting points, not guarantees. Variety, climate, fertility, pruning and local disease pressure can require wider spacing. Check the seed packet and local extension guidance.

How to plan a raised garden bed
A useful raised-bed plan answers three questions before planting: how much growing space is available, how much soil is required and how far apart the mature plants should be. This tool combines those calculations so the layout and shopping estimate stay connected.
Start with reachable dimensions
A bed should be narrow enough to reach the centre without stepping on the soil. Many home vegetable beds are around 3โ4 feet wide, while length can be adapted to the space. Bed depth depends on the crop and whether roots can continue into the ground below.
Plan for mature plant size
Seedlings look small, but crowded mature plants can compete for light and airflow. Use the crop spacing in the planner as a starting point, then check the variety on the seed packet. Trellises can free horizontal space, but they can also cast shade.
Buy a little extra soil
Fresh soil settles after watering. The bag calculator includes an adjustable reserve so you can account for settling, uneven ground and small measuring errors.
Frequently asked questions
How many plants fit in one square foot?
It depends on the mature spacing. Large plants may use one square, medium crops often use four or nine positions, and small roots can use sixteen positions. The planner displays the density for every crop.
Can I use metric measurements?
Yes. Select metres and centimetres. The visual layout still uses an approximately 30 ร 30 cm planning grid, while the soil calculation uses the exact dimensions entered.
Can I plan several beds?
The soil calculator multiplies volume and growing area by the number of beds. The visual grid represents one bed layout, which can be printed or duplicated.
