About This Launch
GardenSums is a free set of garden calculators for raised-bed soil, mulch, compost, topsoil, gravel, grass seed, sod, fertilizer, watering and plant spacing. Each calculator gives the volume plus the number of whole bags to buy. Works in imperial and metric, with a German version. No sign-up required.
Why I Built This
Every spring I did napkin math for mulch, topsoil and raised-bed soil and still ended up buying the wrong number of bags. I built GardenSums so anyone can get a reliable shopping list for their garden in a few seconds, on their phone, without signing up.
