Estimated average beginner seasonal return
Know which crops actually save money before you plant
Skip the guesswork of rising grocery bills and garden startup costs with space-tested harvest calculations.
Unpredictable supermarket markup
Store produce prices fluctuate wildly throughout the season with high packaging and transport markups.
Hidden garden startup expenses
Buying premium soil, raised beds, and unused tools without a plan quickly turns a hobby into a money sink.
Generic gardening advice
Most gardening guides focus on plant care alone rather than calculating your real cost per ounce harvested.
Direct grocery price tracking
We compare your actual harvest yield against standard supermarket and organic market prices.
Space-adjusted yield calculations
See exactly how much money a single square foot or balcony container can return each month.
Clear break-even timelines
Know up front which crops pay off their seeds and soil within the first season and which do not.
Growing herbs, salad greens, and cherry tomatoes yields up to 4x cost recovery.
Low-value root vegetables rarely cover soil and seed outlay in small spaces.
A seed packet can tell you more than most grocery labels, if you know how to read it.
Hybrid is not GMO. Organic does not mean pesticide-free. A root crop is not automatically residue-free. And not every vegetable needs bees to make the part you eat. Learn what the terms mean, choose crops that fit your values and budget, and use fewer inputs without falling for fear-based claims.
