Most garden apps stop
where serious gardeners start.

Vernal™ is a planning tool for gardeners who track beds by name, seeds by variety, and harvests by weight. Built for the grower who's outgrown everything else.

No spam. You'll hear when beta applications open and when Vernal™ launches.

What Vernal™ is

A planning tool that takes your garden as seriously as you do.

Vernal™ handles the full cycle. From laying out your beds and placing plants, through tracking what you sowed and when, to logging what you actually harvested at the end of the season. It connects those pieces so the data you collect this year is useful next year.

The core app is free and open source. Unlimited gardens, full layout tools, complete seed catalogue, planting guide with frost date integration, and harvest tracking with your full season history. No trial period, no feature cap designed to push you to subscribe.

Garden canvas
Design your beds in grid or freeform, whichever matches how you think. Place plants by variety, get companion planting warnings, and lay a past season over the current one to see what changed.
Seed catalogue
Your seeds organized at the variety level, with sowing history attached. Community database backed by Cambium™. Growth stage illustrations for 30+ vegetables and herbs at launch, with community contributions over time.
Planting guide
Calendar, timeline, or list. You choose how to see it. Frost dates and spacing handled automatically. Mark sowings done and the data flows through to your harvest log without any double entry.
Harvest log
Log what you pull, when you pull it, at whatever unit makes sense for that plant — weight, count, bunches. Yields by bed, by variety, by season. Enough data to actually know what worked.

Open source

The core app is free.
That's a promise, not a pitch.

Vernal™ is open core. The application is AGPL-3.0 licensed and the code is public on GitHub from day one. The free tier includes everything most gardeners need: unlimited gardens, the full canvas, your complete seed catalogue, planting guide, growth visualization, and harvest tracking with season history.

Paid features exist (for example, weather station integration, advanced analytics and photo journaling), and they're clearly labeled. But the free tier isn't designed around a ceiling. It's designed to be complete.

Why I Chose Konva.js, and What It Cost Me
Konva.js was the right call for Vernal's garden canvas. What I didn't know going in was which parts of it I could actually rely on.

Why This Exists
"The problem isn't that the apps are bad. It's that they stop where serious gardeners start."
