Peach grafting weather?


#162

I grafted a Winblo peach and a Frolilege apricot on 4/24. At the time,
high temp was 60 and low was 40 for about 3 -4 days . Subsequent weeks, we had temp as low as 34 and 38 F.

Last week they started showing signs of life. But we barely had any sunny days. So far, the highest temp we had never had was 68 for a day. Forget about 70 F. Geafts barely grow

I took these pics today. All they need is sunkight and warmer temp. Am I asking too much?


#163

Glad to see them leaf out.I just grafted my apricots few days a day. The weather is crazy this year, one day in 70s and the next day is in 50s


#164

Thanks, Annie. They are not out of the wood yet. While I don’t discount weather as a factor, it looks to me that quality of scionwood and a location where I put a graft on a tree is more important.

I have noitced that scions grafted on last year’s wood (not rootstock grafting) that is vigorously growing have a higher % of take.


#165

On May 3rd, with a stretch of days in the seventies forecasted, I re-grafted 5 cots (varieties that failed earlier) and a nectarine. Today, all are showing small green leaves (I am comfortable calling them successes).


#166

All of my cot grafts showed small green leaves, but two stalled and failed. But they were both on a large stock and it kept sprouting too many adventitious buds below the graft. If your takes are on small stocks they are almost certainly good I would say.

This year I did much worse on my bark grafts on the big trunks compared to the wedge grafts on smaller shoots. My one apricot that finally took was on a small stock. I think next time I will graft more to the smaller shoots off the big trunks, and less on the big trunks themselves.


#167

Mine are mostly on smaller stocks, either the same diameter as the scion or a bit more. The biggest difference that I have is for Early Blush which is grafted on a stock that is double its diameter.


#168

I grafted some peach/nectarine yesterday.it was in low 80s then 70s today and 60s tomorrow. Not ideal temperature but I think it’s doable. However it is pretty windy today. I start to wonder with all the winds blowing/bending on the branches, would this help the graft heal faster or harm the graft, assuming all grafts are secured attached to the branches, anyone care to comment?


#169

It won’t help. Won’t hurt either if securely attached unless the scion is bumped against another limb. Then it could be knocked out of position.

I count grafting peaches, nectarines and apricot all together here.

We had a very cool and wet spring this year. I was impatient to wait for warm waether (70-80 F). I went ahead and grafted early this year. I was glad I did.

4/24/19 high temp 60, low 40.
Did 2 grafts. 2 took.

5/4/19 high 58. Low 50.
Did 2 grafts. None took.

5/6/19 high 63, low 45
Did 17 grafts. 14 took, 3 did not.

5/18/19 high 73, low 47
Did 2 grafts. 1 took. 1 did not.

Total 23 grafts. 17 took. 6 did not.

Of the 6 that did not take, 3 were grafted to rootstocks that were just potted up a few weeks earlier. No surprise they failed.
The other 3 were Lasgerdi Mashhad and Shah Kar Pareh (2) on a nectarine tree. Not sure about compatibility there.

I am happy with the success rate I got this year.

To me, 3 factors that have helped with successful peach grafting are:

  • consistent weather at least in the 60’s for 3-4 days from the day of grafting on.
  • quality of scionwood
  • position of the grafts on a tree. Grafting on vigorous, one year old shoots on upper part of a tree when possible.

Just my 2 cents.


#172

I also had good results with peaches this year, it was wet and cool here. I think it helped keep the scion from drying out and baking in the sun , some years it switches from spring to hot summer so fast here.


#173

My peach grafting was almost an absolute failure this year. I grafted at different times and used methods same as in the past and got almost nothing out of at least 80 grafts. In the past I’ve had more trouble with persimmons and this year I did 3 grafts on one tree to make sure one would take and all 3 did.

At the moment I’m completely dumbfounded- the more experience I have grafting peaches, the more I try to follow advise of others here the worst results I get.


#174

I had just about the same results,with maybe one working.bb


#175

By the way, I followed all your requirements and always do. However I waited for temps in the 70’s that didn’t exceed the low '80’s. Had no better results from shaded grafts than those fully exposed. I did wait until 5-27 to do it just to be sure of warmth and some dry weather. Next year I will try sooner, but spring started late this year so I did it at least as early as previous years as far as the state of the trees.


#176

Alan,
I am far from an expert. I’ve noticed that when I had good success with peach grafting (2017 and 2019), the 3 things I listed were main factors.

I believe for my area, waiting for 70’s-80’s temp is way too late. From now on, when temp is in the 60’s and stays consistent for 3-4 days, (the longer, the better), I will graft peaches. Not when it’s 70 one day and 40- 50 the next.

Here are my Winblo peach and Florilege apricot grafted on April 24. The earliest peach grafting for me, ever,

Challeger ( I think) grafted on May 6. Lot of success on this day.

And Spring Snow grafted on May 18. I sat on the ground grafting this in-ground rootstock. (no success with newly dug up rootstocks with grafting. Should have waited a year)

This is what has worked for me.


#177

you’re not alone, I feel your frustration. I have very disappointing grafting this year on peach, cherry, and pear , plum was low taken too. I am thinking setup a kinda grafting God/Goddess might helps next year​:smirk::stuck_out_tongue:


#178

Yes, I will try to graft them sooner as I used to. I believe Scott said '70’s and maybe that’s the ticket where he is. The problem is I have lots of grafting of other things to do and it seems like the stonefruit all take best right when I need to be spraying all the orchards I’m responsible to do that.


#179

Can you share the name of the grafting cover/wax? Do you prefer it to tape?


#180

It is parafilm with Doc Farwells grafting compound over it. Doc Farwells seems to no longer be sold in the quart size so I will probably be working on my own recipe for it eventually. I think straight latex caulking or that plus some latex paint would be similar.


#181

Thanks for the info! I have been using a grafting tape and tying it off per recommendations. I have noted that over time the tape has sometimes started to come off. I read that several have checked their graft to see if it has taken, but I hesitated to touch it myself. I see in many of the pics that others do use tape. Just checking in to see what works best–looks like it is an individual decision.
