Embed the Planting Date Finder

Give your readers a free, personalized planting calendar — they enter a ZIP code and get exact start-indoors, transplant, and direct-sow dates for their USDA zone. One line of code, no signup.

Why add it to your site

"When should I plant tomatoes?" is the single most-asked question in home gardening, and the honest answer always starts with "it depends on your zone." A static chart can't answer it for every reader — but this widget does, instantly, from a ZIP code. Drop it into a how-to post, a seed-starting guide, or your spring newsletter and every reader gets dates tailored to their garden instead of a generic national average.

It's genuinely useful content that keeps people on your page longer: the calculator does the frost-date math for over 100 vegetables, herbs, and flowers, so readers don't have to leave to figure out their schedule. There's nothing to maintain on your end — it always shows the current year's dates and stays in sync as our frost data is updated. No account, no API key, no tracking scripts beyond the calculator itself.

Copy the embed code

Paste this wherever you want the widget to appear (most blog and newsletter editors have a “custom HTML” / “embed” block):

One small ask: keep the credit link

The widget is free to use on any non-commercial or editorial site. The only condition is that you keep the “by GardeningByZone” credit link that ships in the embed code (the line below the calculator). That link is how the tool stays free — please don’t remove or nofollow it.

Questions

  • Will it slow my page down? No — it loads lazily and only fetches data when a reader looks up a ZIP.
  • Does it work in newsletters? It works anywhere that allows an <iframe> (most website builders and blog platforms). Some email clients strip iframes — for those, link to the full calculator instead.
  • Can I change the size? Yes — adjust the width/height in the code. The widget is responsive.
