How we estimate your soil needs
We use your pot’s shape, inside measurements, fill depth, and quantity to estimate how much soil you need. We then round up to the next whole bag.
For the best estimate
Measure inside your pots, up to the level you plan to fill. A pot’s listed gallon size may differ from its actual capacity. Plant roots, soil settling, and spillage can also affect how much you use.
Check your bag size
Confirm the volume shown on the package and adjust it if needed. For compressed soil or growing media, use the expanded volume. Quart measurements are treated as US dry quarts.
