Re: Drainage vs rot?

Diana Louis asked a few questions, whict I will attempt to answer.
Our yard is 3/4 acre, containing House and many beds (roses) (daylilies)
(Preannuals) and Iris.  It is quite flat as those of you who know Norfolk
know.  I do not use sand.  Locat sand is too heavy in salt and other minerals
that make iris unhappy.  We ahve a clay base above sand or crushed shells
perhaps three or four feet down; thus I cover it with top soil.  This makes
raised beds about a foot or two high.  I employ the use of vermeculite (Sp)
to help with loosing the soil around the rhizones.  We are in zone 7, but
never know how cold the weather will get from year to year.  I have not kept
track of named iris that had rot.. there wasn't that much to worry about.
 However if it becomes significant, I will put on computor.  Hope this helps.
