Gardening calculators — beds, plants & materials
Lay out plant centers, compare mulch bags with bulk delivery or scale a measured soil-block batch. Free to use, with no account needed.
Mulch calculator — bags & bulk cost
Estimate mulch volume from bed dimensions and added depth. Compare whole bags with bulk cubic yards, including delivery and a separate extra allowance.
Plant-spacing layout calculator
Fit rows of plants into a rectangular bed with independent row spacing and edge setbacks. See a centered layout diagram and download plant-center coordinates.
Soil-block mix calculator
Scale your measured soil-block batch and recipe.
Measure the bed, then choose the method
Plant layouts use your chosen crop spacing and setbacks. Mulch estimates use only the depth being added. Soil-block planning uses your measured batch yield. The defaults are examples, not growing prescriptions.
