How To Grow Vegetables

How we research

How each growing guide is built: which sources we use, how we write for your USDA zone, and what we do when sources disagree.

Start with the calendar

Every guide begins with when the crop can be sown, planted out and harvested in each zone group, and where it will not finish a season outdoors. We write those limits into the opening of the guide rather than burying them, and show them in a planting calendar you can read at a glance.

Where the facts come from

  • University extension publications and government plant-hardiness data
  • Seed-house and nursery information, including variety descriptions and days to maturity
  • Grower forums, treated as reports of experience rather than proof

When sources disagree we say so and explain which we trust and why. Sources are listed at the end of each guide.

Review before publishing

Each guide is read for accuracy, clarity and unsupported claims before it goes live, and revisited when new information changes the advice.

What we don’t claim

We don’t invent statistics, yields or personal growing histories. If we have not grown a crop ourselves we do not write as if we had; products are only marked “tested” when they have been.
