Have a question
about your plan?
Use this address for a calculator issue, a correction to a planning note, or a question about how a result is shown.
What to include
If your question is about a calculation, include the inside dimensions, the depth you want to add, the unit system and the bag or bulk settings you used. Please leave out anything you would not want to send by email. We can explain how the calculator treats the values, but we cannot inspect a garden remotely or replace local growing advice.
Corrections and sources
Planning notes identify their assumptions and link to supporting sources where they discuss growing conditions. If you find an error, an unclear example or a broken link, send the page address and a short description. We review reports when updating the notes.
