Correcting a plant

If a value in the guide looks wrong (spacing, sowing depth, timing or a neighbour), tell us the plant, the value you expect and, if you can, where it comes from: a university extension service, a horticultural society such as the RHS, or a botanical reference. A value is marked as checked only when a named source confirms it, so a source helps us correct it quickly.
