Affiliate disclosure

Last updated: February 15, 2026

PlantWhenNow is a free tool. We keep it free partly through affiliate partnerships with seed companies and garden supply retailers.

How it works

When we link to products (seeds, garden tools, soil amendments), some of those links are affiliate links. If you buy something through one of those links, we earn a small commission at no extra cost to you.

What this means for you

Our planting calendar recommendations are based on USDA zone data and NOAA frost dates. They are not influenced by affiliate relationships. We recommend the same planting dates whether or not we have an affiliate link to a seed company.

Who we work with

We may have affiliate relationships with seed companies, garden supply retailers, and online marketplaces. We only link to retailers we think offer reasonable products and prices.

FTC compliance

This disclosure is made in accordance with the Federal Trade Commission's guidelines on endorsements and testimonials (16 CFR Part 255).
