Late season dormant scionwood grafting

Late season dormant scionwood grafting
June 16, 2019 10:41PM
I just found some scionwood in my refrigerator which I had somehow missed during grafting season. Here at our orchard the trees are just finishing full bloom, and I'm wondering how late grafting with dormant scionwood can be done- does anyone have any experience working this late into the season?

I've never grafted this time of year, but I would try side veneer grafting them rather than whip and tongue. JMHO

I finished up grafting a row in the nursery about two weeks ago when a class was here at the farm. Those buds now showing green. The cost of late grafting is limited growth in year one but I think juicy scionwood will readily take. It helps that things remains relatively cool.

I have successfully grafted later than that. In fact, I generally keep some wood into July, so I can replace a failed graft (yes, it sometimes happens). However, later grafts usually will not get as much growth on the first year, but it is better than waiting another year before making the graft.

I don't know if its worth opening this thread again but here we are at grafting season again.
The general rule of thumb with dormant grafting would say that its not so important how late in the growth the rootstock. In fact if your your doing a graft that requires slipping of the bark then you'll have to wait at least that long, like bloom or later.
Scionwood however should always be as close as possible to completely dormant. That's not always possible I realize. I myself have opened up a bag of wood in May to find buds starting to push. Its worth going ahead with this wood in my opinion but percentage of takes will suffer. I now have a small fridge in the barn that is dedicated to scionwood so I can keep the temp just above freezing. I found that keeping wood in the home fridge to be problematic.

update to this thread, already helpful, but now is 2021, a cold spring here in SW Ontario 5b. still frozen ground and subzero nites tho we had week long thaw two weeks ago.
I'm still pruning and thinking could I use any of these shoots for grafting or is it too late this year.
A variation is: would it be better to take the scions now and wait till temps warm to do the graft on rootstock in the ground?
Our last frost date is usually apr 29.
thanks for quick reply from the community!

I have had poor luck with field grafting when a freeze follows. I wait until all chance of freezing is past before doing outside grafting.

Thanks Tom for quick reply. I'm going to give it a shot. Collect good scion wood now and store in fridge well protected from drying out, and in a month do the grafts. The rootstock is 5 yrs old still in the nursery, should I leave it in place after grafting for another year, or move and graft at same time?

grafts are fragile. giving it a year before moving it will lessen the chances of you busting it off.

OR you can move it, and then do the grafts, if you want to do it all in one year.

I was thinking along the same lines. move first then graft. do you think it really matters if I wait as long as possible, ie up to bloom to do the grafts to let the first root flush get started?

I would say that transplanting as early as possible is the first priority. Get it done while the tree is asleep. As far as when to graft, well, not sure how important what the roots are doing below is. Top doesnt have a lot to do with it so far as I know. Biggest issue for me has been making damn sure it is not going to freeze before the cambium tissues merge.
