The plant collection tracker lets you build a digital record of every plant in your home. Log watering, fertilizing, and repotting events for each plant and see at a glance which ones need attention. All data is saved locally in your browser — completely private.

How to Use the Plant Collection Tracker
The plant collection tracker helps you maintain a care log for every plant in your home. Instead of trying to remember when you last watered each plant, the tracker shows you exactly how many days ago each plant was watered and whether it is overdue. All data is stored locally in your browser — nothing is uploaded or shared.
Adding Your Plants
Click the "Add Plant" button to open the add form. Select your plant from the dropdown (populated from the 100-plant houseplant database) or choose "Custom plant" and type any name. Add a nickname or location to help you distinguish multiple plants of the same species. Set the last watered date and watering frequency — the tracker will alert you when watering is due.
Logging Care Events
Click any plant card to open its detail panel. The "Log Water", "Log Fertilize", and "Log Repot" buttons record today's date as the most recent care event. Each event appears in the care history log with its timestamp. The watering due status updates immediately after logging — the card will turn from red back to green when you log a watering.
Understanding the Status Colors
Plant cards have a color-coded border: green for recently watered (within frequency window), yellow for water due within 2 days, and red for overdue. The stats bar at the top shows how many plants need water today across your entire collection.
Backing Up Your Data
Use the "Export JSON" button to save your entire collection as a downloadable JSON file. This is your backup — store it somewhere safe. If you ever clear your browser data or move to a new device, use "Import JSON" to restore your collection. We recommend exporting monthly as a simple backup routine.
FAQ
Is my plant data stored securely?
Yes. All plant data is stored exclusively in your browser's localStorage — it never leaves your device and is never sent to any server. Your collection is completely private. You can also export your data as a JSON backup file at any time using the Export button.
Will my plant data be lost if I clear my browser?
Yes — clearing your browser's localStorage or site data will erase your plant collection. To prevent data loss, regularly use the Export button to save a JSON backup. You can re-import this backup at any time using the Import button.
Can I use this on multiple devices?
The tracker stores data locally in your browser, so it does not sync between devices automatically. To use it on multiple devices, export your collection from one device and import it on the other. This also serves as a useful backup routine.
How does the watering due alert work?
When you add a plant from the database, the tracker uses that plant's species-specific watering frequency. Cards turn yellow when watering is due within 2 days, and red when overdue. The days-since indicator on each card shows exactly how long since you last watered.
Can I add plants not in the database?
Yes. Select 'Custom plant' from the plant dropdown and type any name. For custom plants, you set the watering frequency manually when adding the plant.
How do I log a watering or fertilizing event?
Click any plant card to open its detail panel. Use the 'Log Water', 'Log Fertilize', or 'Log Repot' buttons to record a care event with today's date. Each event is logged with a timestamp in the plant's care history.
