Apple & Pear winter cuttings never root

ZONE 6 stem propagation suggestions needed.

For a decade now, I have futilely attempted to grow apples and pears from winter cuttings harvested in December, January, or February.  With 2-dozen fruit trees, I usually have 200 to 400 cuttings.

Same results every year.  Stems stay green up to spring. Callus forms on most pear and few apple stems. Roots never form.  
The indoor cuttings get moved outside to a north facing wall by May. All cuttings in coir or peat get pulled out and put in sand or perlite for drainage.
They get watered with a fungicide or with creek water every week or twice per week depending on weather so they stay hydrated.  
By June, they're all dead from one of three conditions. 1) Just dried out and dead (smallest cuttings generally), 2) bases are black, 3) covered in mold even with regular applications of fungicides.

I've tried:
           - new growth up to 2-year old wood
           - stored vertically and horizontally in substrate.
           - with and without apical meristems/buds still attached
           - ends and tips waxed or left natural
           - various length ranging from 3" to 14"
           - leaving all buds on stems or stripping all but 3-4 buds
           - clean bottom cuts and intentionally damaging the bottom bark to promote callus
           - no heat and bottom heat with electric mats
           - individually and mixes of damp (well drained) coir, perlite, peat, sand, & even a damp towel
           - treated and untreated with fungicides (sulphur, lime, various retail products)
           - treated and untreated with growth hormones (Woods, Clonex, Rootone, Hormodin, & willow extracts)
           - storage outdoors in partial sun to complete shade, as well as an unheated garage, a cellar, and in a small greenhouse
 



How can I get cuttings to grow?

I have found I have much better luck taking summer cuttings.  I pick off all but one leaf then put them a bunch of them in a bucket of water with a bit of rooting hormone in it.  I leave them in the bucket for a month or so,  Any that start growing new leaves I plant,

I try to take my cuttings from apple trees that grow on their own roots.  In my area it is very common for roots not to be hardy enough for our climate so I search for ditch apple trees that grew on their own and produce a somewhat edible apple.  When I plant them I plant them way to thick,  Like two cuttings per hole, and a hole every 3 feet.  I plant them and forget them so nature and animals take quite a toll on them.

This batch of apple cuttings were done this morning and have been:
Cut to 9”
Soaked in fungicide for 2 minutes
Dried 20 minutes
Tops sealed with wax
Scarified the bottom
Soaked in a rooting hormone solution
Temporarily stored upright in perlite (filled to the top of the pot).
Set in an unheated detached garage.

Now what should I do?
