Your garden,
thoughtfully planned
Trowel & Error is an intuitive garden planning tool for real gardeners — drag, drop, measure, and grow with confidence. Because the best gardens don't just feed a household. They start conversations, build friendships, and root a community in something living.
From blank canvas
to growing plan
Three simple steps between you and a garden you can actually follow.
Build your plant library
Browse a built-in catalog of common vegetables, herbs, and flowers. Add your own custom plants with names and icons. Select exactly what belongs in your garden this season.
Draw your beds
Add garden beds in any shape. Rotate and resize them to match your real outdoor space. Set your compass orientation so sun direction is accurate.
Plan, adjust, export
Drag plants onto your beds and fine-tune the layout. When you're happy, export a clean PDF to take outside or share with someone.

Gardens grow more than
vegetables
This app was born from a garden in Chicago — tended for decades by a woman who understood something most planners miss: that a well-kept garden is an open invitation. Neighbors stop. Conversations begin. Seeds get traded. Recipes get shared. Something that started in the soil ends up at the table, and then at the heart.
She taught that gardening is one of the most generous things a person can do — not just for their own family, but for everyone who walks by and sees something growing. Trowel & Error was built to carry that spirit forward: thoughtful planning in service of something larger than the harvest.
A song written in her memory — for the gardener who taught us that roots run deeper than soil.
"For Abuelita — who taught me that gardens grow neighbors."
