In the case of the hardwoods, often they are propagated in the open at this
time of the year.

You do not want the cuttings to dry out completely so the soil should be
moist not wet. Use a well drained media (ie: with some sand for draninage.)
see for ideas: http://www.rooting-hormones.com/cutcare.htm

If you want, you can make a simple covering by pulling over the cuttings a
clear plastic film and tack it down at the edges. Critical is that it is not
too humid inside the propagation area such that it is too wet and fungus
forms.
In the case of the semi hardwoods and herbaceous cutting you want to keep
more humity like the  rose information (they need more control to keep the
more sensitive stem cells from drying out.)
See for ideas: http://www.rooting-hormones.com/rose.htm

In the case of hardwoods you have two possible methods of rooting hormones
application (1) long soak of the basal end in a low concentration solutioin
of the rooting hormones (25-50 ppm IBA @ 4-8 hours)
See for ideas: http://www.rooting-hormones.com/wst.htm

 or (2) a moderate concentration of dry powder such as IBA @ 0.3% or 0.8%.
See for ideas: http://www.rooting-hormones.com/Drydipdemo.htm
