Re: Sawdust

Sawdust from home construction is very fine compared to sawdust from a lumber
mill that saws logs into rough lumber.  And hardwood sawdust from a lumber
mill is finer than pine sawdust.  The finer it is, the more likely it is to
pack down into a dense surface almost impermeable to water and air once it
dries.  The Couturiers at Sunnyridge Gardens in Knoxville routinely use
lumber mill sawdust to heavily mulch their commercial iris beds - right up to
the rhizome and occasionally spilling over on top of them.  The are on a
ridge top on not very good clay soil (shallow acid shale type).  They do
rotate their production beds regularly with their daylilys.  I think they use
hardwood 'dust'.
