Contact

Found an error, or have an idea for a new tool? Email us at hello@example.com. We read every message.

What to include

• The page address where you saw the problem.
• The numbers you typed and the result you expected.
• A link to your source if you think a formula is wrong.

What we can help with

We are glad to hear about mistakes, broken links and ideas for new tools. We cannot visit your yard or give a quote. For plant health questions, your local Cooperative Extension office or a certified arborist is the best place to ask.

You can read how the tools work on the About page. How we handle data is on the Privacy page.
