Useful tools for real garden decisions.
Interactive planning, historical climate analysis, live weather checks, reusable garden measurements, seed-batch evidence and transparent calculators built around jobs gardeners repeat throughout the season.
Choose the plant before choosing the tool.
The Plant Library keeps annual vegetables, herbs, companion flowers, berries, perennial edibles, fruit trees and vines under one naming system, including common regional aliases.
Turn frost dates into a crop calendar.
The Growing Season Planner connects historical or manual frost dates with crop timing, succession sowing, editable variety overrides and calendar export.
Build a raised bed from frame to planting.
The Raised Bed Build Pack connects timber cuts, soil volume and crop layout while carrying your saved dimensions between steps.
Design a complete drip-irrigation zone.
The Irrigation Planner connects area, emitter calibration, source-flow checks, weekly water demand, forecast rainfall, runtime and tank capacity.
Measure a bed once, then reuse the area.
The Garden Area Calculator saves a real m² measurement into My Garden. The same area can then feed fertilizer application, rain-adjusted watering, crop and harvest locations, and bed-level yield analysis.
Test the seed batch you actually have.
The Seed Germination Rate Calculator measures your observed percentage, first-sprout timing and repeat batch history instead of relying on a generic seed-age assumption.
