I'm not sure what you mean Gavin?
Do you mean a show schedule?
for example like this;
http://www.thegardenersalmanac.co.uk/Data/Show%20schedule/Show%20Schedule.htmOr do you mean how to time produce so that it will be ready for show day?
If you mean the latter, I don't think there is a simple answer to that other than experience!
Then if you mean ; what is the judge looking for when judging, check with the RHS they have a book on the subject.
My copy is rather old so I am not sure if all that is in it applies to this day, although I would have thought it still does!
