Search "best bonsai app" and you'll get lists that lump together three very different tools: plant identifiers, general houseplant care apps, and dedicated journals. They're good at different jobs, so the honest answer to "which is best" starts with "best at what?" And bonsai has a twist most lists miss — it's a years-long project, not a weekly chore, so the tool that fits it looks different from a generic plant app. Here's the map.
Best for journaling & tracking growth over years: Bonsai
Bonsai (ours) is built narrowly for what bonsai growers actually do: watch a tree change over years and keep its care log in one place. You get a per-tree photo growth timeline you can swipe through by season, a watering reminder and care calendar that respects the fact that bonsai watering is daily in summer and sparse in winter — never a fixed seven-day rule — and species-aware notes (juniper, ficus, jade, pine, elm, azalea, Japanese maple) that travel with the tree across years and owners. It won't identify a mystery species for you, and it's not a 10,000-plant encyclopedia. It's the pick if you already grow bonsai and want a beautiful record you'll actually open. Everything stays private, on your device, with no account.
Best for identifying a tree or diagnosing problems: PictureThis
If your main need is "what species is this?" or "why are these leaves yellowing?", an identification app is the right call. PictureThis recognizes plants from a photo and flags likely diseases from a large database. It's a momentary lookup rather than an ongoing diary — great for the occasional question, but it's not where you'd keep your tree's multi-year history.
Best all-round houseplant care: Planta
Planta is a polished, broad houseplant-care app with watering schedules, light meters, and tips across many species. If your bonsai lives among a larger collection of regular houseplants and you want one app for all of it, it's a strong generalist. The trade-off is that its schedules are built around typical houseplants rather than the seasonal pruning-and-watering rhythm of bonsai, and its best features sit behind a subscription. We drew the same focused-vs-broad line for succulents in Succulent vs Planta.
Best for learning technique: books, forums & Bonsai Empire
No app teaches you to wire a branch or style a nursery tree as well as dedicated learning resources do. Bonsai Empire's courses, classic bonsai books, and active communities like Reddit's r/Bonsai are where the craft is actually learned. Pair that learning with a journal to record what you tried and how the tree responded — the two together beat any single "does everything" app.
Which should you pick?
| If you want to… | Best pick | Why |
|---|---|---|
| Journal your trees & track growth over years | Bonsai | Photo growth timeline + species-aware care log |
| Identify a species or diagnose a problem | PictureThis | Fast photo ID & disease flags |
| Care for a mixed houseplant collection | Planta | Broad schedules & tools |
| Learn styling, wiring & pruning | Bonsai Empire / books | Real technique, not an app feature |
"I tried a general plant app and it kept nagging me to water on a seven-day timer — useless for bonsai. What I actually wanted was to see how the tree changed across three summers. That's a journal, not a checklist."
The bottom line
If you grow bonsai and your real reward is watching a tree evolve over years, a focused photo journal beats a do-everything care app. Reach for an identifier when you hit a mystery, a broad app if bonsai is one of many houseplants, and books or courses to actually learn the craft. Match the tool to the job and you'll keep using it — season after season.
Frequently asked questions
What is the best app for bonsai care?
It depends what you need. For journaling one collection and tracking watering, pruning, and growth over years, a dedicated bonsai journal like Bonsai fits best. For identifying a tree or diagnosing a problem from a photo, an identifier like PictureThis is stronger. For general houseplant schedules across many species, a broad care app like Planta works. Most serious growers pair a journal with an occasional identifier.
Is there a free bonsai app?
Yes. Bonsai is free to start with no account required and an optional one-time upgrade. General plant-care and identification apps usually offer a free tier but move their best features — unlimited identifications, detailed care plans — behind a subscription.
Why don't generic plant care apps work well for bonsai?
Because they treat a bonsai like any houseplant: a fixed every-seven-days watering reminder and a generic checklist. Bonsai watering is its own discipline — often daily in summer, sparse in winter, never on a fixed schedule — and the hobby revolves around pruning seasons, ramification, and years of slow change. A tool built around a photo growth timeline and a species-aware care log fits the way bonsai actually works.
What's the best app to track a bonsai's growth over the years?
For a multi-year visual history you want a photo-first journal, not a reminder app. Bonsai is built around exactly that — every photo you add builds a growth timeline you can swipe through by season, so you can watch deadwood weather, branches ramify, and a nursery starter turn into a tree with real character.
