Affiliate Disclosure

Some links on Trowelful are affiliate links. If you click one and make a purchase, we may earn a commission at no extra cost to you. This helps keep our calculators free.

We only link to products relevant to what you're calculating (e.g. bagged soil, mulch, raised-bed kits, seeds). A commission never changes the numbers our calculators produce or the advice in our guides.

As an Amazon Associate, Trowelful earns from qualifying purchases.

We also participate in other affiliate and retailer programs. Product availability, pricing, and specifications are controlled by the retailer, not by us — always confirm details on the destination site before buying.
