Clogherhead, are you asking that more people join the debate in order to stimulate more ideas? There are some very knowledgeable people using this forum and others (like me) who are very much learners or who (like me) only know about certain aspects of gardening. I come on to the forum to learn as much as to contribute. I do think it takes a bit of courage to contribute, too. There is always the possibility of being shot down in flames and some people mind that more than others.
I have not idea what griddish means but I have a horrible suspicion that I understand all too well what 'a bit dim' means.
