Frequently asked questions
What seed packets work with the scanner?
Any seed packet with planting information printed on it. Just snap a clear photo of the front and back, and we'll extract the details. It works with all major seed brands.
How do you calculate my planting dates?
We use your zip code to determine your USDA hardiness zone and average frost dates based on historical climate data. Your planting timeline is then calculated from your seed packet data and those frost dates.
Can I use this outside the United States?
Yes! LizPlants works internationally. We calculate frost dates from historical climate data for any location worldwide and determine a USDA-equivalent hardiness zone based on your local temperatures.
What if my seed packet is missing information?
No problem. If the packet doesn't include details like spacing or days to germination, we'll fill in typical values for that plant variety automatically.
Can I add plants manually without scanning?
Yes! You can add any plant by hand and fill in the planting details yourself. Scanning is just the fastest way to get started.
What's included in the free plan?
You get 3 seed packet scans, 1 garden, full planting timelines, a garden calendar, and printable task lists — no credit card required.
Do you collect my exact location?
No. We only ask for your zip code to determine your growing zone and frost dates. We never collect GPS coordinates, track your location, or share your data with third parties. Your privacy is a priority.
What if I'm not starting from seed and bought seedlings?
That's totally fine! Just skip or mark complete the seed-starting tasks (like "Start Indoors" and "Harden Off") and your timeline will adjust automatically. The transplanting, care, and harvest dates still apply.
Built by a gardener, for gardeners
Hi! 👋🏼 I'm Liz, a software engineer who really likes to garden. I built LizPlants because I bought way too many seed packets one spring and couldn't keep track of when to plant what. So I did what any engineer would do: I built an app for it. This isn't made by a big company — it's a real tool I use in my own garden, and I hope it helps yours too.
