Green Bio Life Gardening Calculators & Planning Tools
Free, practical tools for composting, soil carbon estimates, seed starting schedules, herb harvest planning, botanical name lookup, and herbal tea preparation. Each calculator is designed to give clear guidance using established horticultural and food-preparation references.
This tool was built by Serge, MSc., a plant biologist and environmental scientist with a BSc in Plant Biology and an MSc in Environmental Biology and Biogeochemistry. My research focused on how climate warming affects soil carbon cycling in boreal forest ecosystems. These tools are for educational purposes and give practical guidance, not professional advice.
Compost & Soil Tools
Compost Ratio Calculator
Balance carbon-rich browns and nitrogen-rich greens to help maintain an efficient compost pile and reduce common problems such as odors and slow decomposition.
Open calculatorGarden Soil Carbon Estimator
Estimate the amount of organic carbon stored in your garden soil from area, depth, bulk density, and organic matter assumptions.
Open calculatorSeed Starting & Harvest Planning
Seed Starting Calculator
Work backward from your last frost date to find indoor sowing dates, transplant timing, and outdoor sowing windows for common garden crops.
Open calculatorHerb Harvest Calendar
Plan the best harvest periods for culinary and medicinal herbs, including guidance on leaf, flower, and seed collection timing through the growing season.
Open calculatorPlant Identification & Herbal Preparation
Botanical Name Finder
Look up common garden plant names and find their corresponding botanical names to improve plant identification, labeling, and record keeping.
Open calculatorHerbal Tea Steeping Guide
Find recommended steeping times, water temperatures, and herb-to-water ratios for a range of common herbal infusions and tisanes.

Compost performance, soil carbon content, plant growth, and herbal preparation results vary with climate, soil conditions, plant varieties, and handling methods. Always adapt the results to your local conditions and reliable horticultural guidance.
