About GardenPlot

Soil volume for a raised bed or a pot, Mel's Mix measured by volume, bag counts and the plant spacing that fits the bed.

What the tools are built on

• A 12% settling allowance is added, because bagged soil is sold by dry volume and compresses once watered.
• Tapered pots are calculated as frustums: a 16 inch pot with a 12 inch base holds about 30% less than the cylinder its top width suggests.
• Mel’s Mix is given as equal parts by volume, not by weight: compost, peat or coir, and vermiculite or perlite.
• Plant spacing produces a planting grid and conventional spacings for 25 vegetables and herbs.
• Filled soil weight is reported, because a saturated raised bed or balcony planter is several hundred kilograms.
