@ltilton. Here is what I do in answer to the questions I sent. Perhaps it can help you next time.
Where do you get your scion wood from (eg. private or commercial sources, what growing zone). What zone are you.
Majority from private trades and purchases. Majority scions cut from zones as cold or colder than mine (zone 4).
When is the wood cut.
All cut while dormant, in zone 2-3 cut during slight warm spells in January. Zone 4 cut in January, February or early march, generally when daytime temperatures come above zero.
Is it treated prior to shipment.
Ideally 10 seconds in a 10% bleach solution then rinsed in water. If this is not done by the shipper I do so when it arrives and I handle the wood with latex gloves to avoid seeding with bacteria/fungus.
How long from cutting to shipping is it and how is it stored during that period.
Ideally cut and shipped within a few days. While waiting stored in the fridge wrapped in paper towels that have some water sprayed on them (not fully damp), then kept in freezer zip locks in fridge.
How is it shipped to you (regular post, express, ect).
I always pay for shipping express leaving a Monday. I would rather it stay in their fridge a few more days that risk a weekend at room temperature in the post office.
How was it packaged. (loose, ziplock, ziplock with wet paper, wrapped in parafilm, ect)
As described above. Have received some with very wet paper towels, usually some fungus growth is visible with the really wet paper. I have also received scions that we're wrapped in parafilm only then direct in a zip lock, seems to be ok but I wonder about long term storage vs being exposed to some humidity.
How long from shipping to arrival.
Ideally by Friday of same week. Frequently arrives after 2-3 days.
Once you get it how do you store them.
If pre-bleached I check dampness of paper towels and replace if too wet or moisten if too dry then suck air out of ziplock and keep in top shelf of fridge below air entry.
When do you start grafting? Eg. what date and what is going on at that time? Snow still on ground with everything dormant and many freezes still to come? Before last frost but buds swelling? Leaves at 1/4 inch green?
Apples/pears generally at time of melt when most snow gone and buds are swelling. Could wait later but I have so many to do I start earlier. Generally 3rd-4th week April.
Plums, apricots, once buds are starting to open with leaves at 1/4 inch. 1st-2nd week May.
How do you do your grafts?
Inside I wrap all scions in parafilm and label with tape. It is warmer and more comfortable than doing outside. I then cut the rootstock/branch, cut the scion right through the parafilm. Do the graft (cleft, whip/tongue), wrap the union in parafilm then tightly wrap the union in electrical tape starting from rootstock/branch then up the scion just above the union. If large calibre bark graft or cleft I put toilet seal wax before the parafilm to seal the large cracks. Mid summer I slice the electrical tape to avoid girdling and remove it completely in the fall. Having the electrical tape ON TOP of the parafilm avoids any bark damage when removing.
What are you using to cut first. Shears, knife.
Standard pruning shears and then an exacto knife with interchangeable blades for the cuts. I generally change the blade After 15-30 grafts.
Are you cleaning your knife between cuts (10% bleach, pine sol, 70% alchohol) and if so are you drying thouroughly?
I have tried pine sol but strips the oils on my shears and promotes rust. Tried 10% bleach but the rust comes even faster. Now I use rubbing alcohol. I generally only clean my shears/blade between trees, not after each cut.
What grafts are you doing? Cleft, whip, bark?
60% cleft, whip/tongue, 30% omega tool, 10% bark grafting.
Hope this helps you for next year. I bet if you do nothing else different other than get viable scion wood, you will see a massive increase in takes.
