After searching for any info on the ways of trimming and pruning Dutch type scapes I came across this video. While it might make some of you squirm going to town to your nicely grown in tank with a pair of scissors this is required to keep a nice and manicured scape. I have came to the conclusion that the best info and videos I have been able to find are from the European aquarists.
And another one. Don't expect to understand a word they say unless you happen to speak their language.
