My friend put in a row of new gladioli corms but the flowers didn't
open
properly on any of them. I suspect this is caused by thrips?? Will
they
always be affected or will they be alright next year, i.e. is it
better to
start over with a new lot and is there any preventative measure to
take?
Thanks in advance?

Robert,

This very good site will hopefully answer your questions. I notice that
it deals with the thrips which you mention.
