Dear All,
Here is the reply of Gordon:
"In reply to the query of Rob from Tasmania, I am happy to oblige.
 "Firstly a copy of my talk from the recent IBSA symposium might be of help
(see other Email).  In addition to this however, all my bulbs/corms grown
under cover receive no water during the dormant period and remain totally
dry.  This also applies to 1st and 2nd year seedlings, which tolerate the
same management as mature bulbs.  If they show signs of growth in the early
Autumn I will immediately begin a programme of watering (including
disinfecting).  However I only normally begin watering, should there be no
signs of growth on the 15th of April of the year.  This actually goes for
all my winter rainfall bulbs and corms."
