About SproutGuide
SproutGuide (sproutguide.net) is an interactive web app built to help gardeners plan their plots, track every planting, and get season-aware care guidance — without handing over more personal data than the job requires.
A digital garden planner
SproutGuide is a privacy-first, offline-capable Progressive Web App for planning yards and beds, choosing companion-friendly plant pairings, calculating irrigation needs, and following a USDA-zone-aware planting calendar. It works as an installable app on phone or desktop, and keeps working without a signal once it's loaded.
Built by a gardener, for gardeners
Most garden-planning tools are either spreadsheets or bloated apps that mine your data for ads. SproutGuide was built as a focused, single-purpose tool: map your yard, place your beds, know what to plant this week for your specific hardiness zone, and get a nudge when something needs water or attention — nothing more, nothing less.
The tools inside
- A visual, zoomable yard and bed planner for laying out multiple garden beds
- A companion-planting checker that flags synergistic and antagonistic plant pairings
- An irrigation calculator that estimates watering needs from bed size and plant mix
- A USDA-zone planting calendar with weekly sow/transplant/harvest guidance — see the planting guides
- AI-assisted plant diagnosis from a photo
You can try lightweight versions of some of these — no account needed — on the free tools page.
