Evergreen cannabis content is anything anchored to how the plant works — terpenes, decarboxylation, COAs, storage, tolerance — because biology does not follow the news cycle. Prices, laws, and product roundups decay in months. Build the library on the first kind and publish the second kind knowing its shelf life.
Sort your topics by decay rate
Every cannabis topic sits somewhere on a decay curve. At the slow end: what myrcene does, why edibles hit later than flower, how to read a lab report, how to store product. Those answers were true five years ago and will be true in five more. At the fast end: this month's menu, "is weed legal in Ohio," current prices, purchase limits. In the middle: anything mentioning specific products or specific regulators. Sort before you write, because the decay rate should set the format, the depth, and how much you invest.
Strip the expiration dates out of durable pages
A page about edible onset time becomes dated the moment it says "as of this year" or quotes a price. Write durable pages so nothing in them expires: explain the mechanism, use ranges instead of prices, and push anything legal or state-specific into a linked page built for updates. One guide on this site about COA reading has needed exactly two touch-ups in its life — both link fixes. That is what topic discipline buys you.
Run a boring maintenance calendar
Evergreen does not mean abandoned. Put every durable page on an annual review: click the links, re-check any number, confirm the examples still make sense. Pages that touch laws or limits get reviewed twice a year — or better, get those details removed so they can stay on the annual cycle. Track it in a spreadsheet with a URL, a last-reviewed date, and a next-review date. Twenty minutes per page per year keeps a library compounding instead of rotting.
A worked example
Two posts published the same week: "Croptober deals roundup" and "why does cannabis smell like that — a terpene primer." The roundup earns a traffic spike for six weeks, then flatlines to nothing by January; that is fine, it did its seasonal job. The terpene primer starts slower, but it collects rankings, picks up internal links from every strain page that mentions limonene, and three years on it is still the site's steadiest page. The lesson is not to skip the roundup — it is to know which one is the asset and budget accordingly.
Key takeaways
- Plant science, lab reports, and storage advice are evergreen; prices, laws, and roundups are not.
- Keep expiring details — prices, dates, statutes — out of durable pages or in linked update pages.
- Review evergreen pages annually, law-adjacent pages twice a year, on a tracked schedule.
- Publish timely content for its spike, but recognize the evergreen piece as the asset.
Frequently asked questions
What cannabis topics are truly evergreen?
How the plant and its compounds work: terpenes, decarboxylation, reading a COA, storage, tolerance, edible onset. The biology and the lab science do not change with the news cycle, so pages built on them keep answering searches for years.
What decays fastest?
Prices, product roundups, legalization status, and purchase limits. Menus turn over in weeks, laws change every session, and a "current state of" post is wrong within a year. Publish those knowingly, as timely pieces, not as long-term assets.
How often should evergreen pages be reviewed?
Once a year is enough for true evergreen pages — check links, examples, and any number that could have drifted. Pages that mention laws or limits move to a twice-a-year cycle, or get those details cut so they can stay annual.
Should the publish date change after an update?
Show an updated date when you actually revised the content, and leave it alone otherwise. Date-bumping unchanged pages is detectable and burns trust with readers and search systems for zero gain.
What ratio of evergreen to timely content works?
Most cannabis sites do well weighting heavily toward evergreen — think four durable guides for every timely post. News earns spikes and links; evergreen carries the baseline traffic that compounds. The mix shifts if you are a news brand, but retailers rarely are.
