'ordentlich' and 'kraut' are opposites here when it comes to order. 'ordentlich' describes something that is tidy, clean, and well organized. 'kraut', by contrast, means jumbled or chaotic, but as a standalone adjective it is very rare and sounds unusual. The phrase 'kraut und Rüben' (a complete mess) is often more natural. In everyday language, people usually say 'unordentlich' or 'chaotisch' when they mean the opposite of 'ordentlich'.
