"Some of my oldest bonsai trees have been with me for more than thirty years.
When I tried to document their story, I realised almost all photos from the early years were missing.
I couldn't remember exactly when I had repotted them.
When exactly I had acquired them.
Which styling steps had been made.
Which pots they used to live in.
That history is lost.
That's why I built Bonsai Diary.
So that doesn't happen to me — or to anyone else who loves bonsai."
— Thomas, developer & bonsai enthusiast
Every step your trees take, recorded — organised by what actually matters.
Log entries with photos, dates and types — watering, fertilizing, pruning, repotting, wiring and more. Filters show at a glance which trees need attention. Never miss repotting season again.
Photos spanning months and years — watch your tree grow. With captions, custom ordering and pinch-to-zoom right inside the app.
Understand what your tree needs. Photos and symptoms feed into an individual diagnosis — tailored to your species, care history and location. The diagnosis automatically becomes part of the development history.
Generate a public development history with one tap and share it via link — no app required to view it. Anyone can discover the story of your tree.
Link every tree to a smart tag or QR code. One scan — instantly on the detail page. Perfect for exhibitions, bonsai clubs and sharing with the community.
When a tree changes hands, its complete history goes with it. Via QR code package: the new owner imports the full documentation with one scan.
