Independent gardening reference, not an extension office. Timing comes from public frost and hardiness-zone data. How we check our facts

Contact and corrections

Spotted a wrong planting window or an out-of-date frost date? Tell us and we will check it against the source.

Report an error

Email contact@plantbydate.com with the address of the page and a link to the official source that shows the correct figure. A link to the source helps us fix it faster.

We cannot help with your own garden

We are not an extension office and cannot diagnose plant problems or give advice for your specific site. For that, contact your local cooperative extension office.
