Embed any of our 21 tools on your site

Have a gardening blog, university Extension page, or nursery website? Drop in one of our calculators or finders with a single iframe. Each embed auto-resizes to fit content, runs entirely client-side, and links back to the full tool.

How to embed

  1. Click "Copy embed code" on any tool below.
  2. Paste the iframe into your site's HTML.
  3. That's it. The embed auto-sizes via postMessage and inherits ~no styling from your site.

Optional: include this resizer snippet on your page to enable height auto-resize:

<script>
window.addEventListener('message', function(e) {
  if (e.data && e.data.type === 'opc-embed-height') {
    var iframes = document.querySelectorAll('iframe[src*="outdoorplantcare.com"]');
    iframes.forEach(function(f) {
      if (f.src.indexOf(e.data.source) !== -1) f.style.height = (e.data.height + 20) + 'px';
    });
  }
});
</script>
