How can I add growzone finder on my shopify store

Shopify Apps

Topic summary

A Shopify store owner selling plants wants to add a grow zone detector feature (similar to a competitor’s site) that identifies USDA planting zones based on customer ZIP codes.

Two solutions were proposed:

  • Custom implementation: Use a free API (phzmapi.org) with JavaScript to fetch grow zone data from ZIP codes, then display zone-appropriate plants using product tags
  • App-based solution: Install the “Growzone Finder” app from the Shopify App Store

The original poster thanked the contributor who suggested the app solution. The discussion appears resolved with actionable options provided.

Hey, we’re selling plants and I recently saw on one of our competitors they have a growzone detector that shows the planting zones from a ZIP code, are there any themes that have this? Or how can we do the same?

This is the site https://gardeningwithcreekside.com

Thanks!

Hi @paolaghaddar ,

Best possible solution will be to Add a ZIP code input on your store and use the free API (https://phzmapi.org) to fetch the USDA grow zone. Then display the user’s grow zone and optionally show zone-suitable plants using product tags (e.g., zone_6, zone_7).

No app needed just JavaScript + API.

Please let me know if you need more clarifications over this .

Thanks !

You’d need to either build it custom or use an app.

This one should do it https://apps.shopify.com/growzone-finder
