Of the four options listed I think I got the 1/4" wide by 6" long. A quarter pound is a lot. To close a cleft or a whip and tongue you catch the standing end under the running end, wrap with the running end until you are nearly out of rubber, and then catch the end under the last wrap. Doesn’t take much practice before you have it mastered! then seal the whole thing up with parafilm. Or, you can do it the other way - seal it first with parafilm and bring it up snug with the rubber. Just seems to make sense to me to cinch first, seal second, but I think it’s done both ways.
It’s easier with temflex, but like I said I get carried away with temflex sometimes, and I’ve got all these derned rubbers …
I like that approach.
You know, I sometimes think somebody should make like a bullet-point or check list of dos and don’ts for grafting. There are a lot of little details you need to get right. Every time I learn another thing I shouldn’t have overlooked!
It’s one thing to have videos and blogs and essays, but sometimes you don’t so much need a how-to. You really just need a checklist.
The problem with that is the way that works well for one person might not work well for another. I’m still a newbie with grafting but have had really good success with the following:
Graft at the right temperature for the species - but then again I didn’t follow this rule for plums and got 93% take rate
Wrap the entire scion in parafilm BEFORE grafting
Use cleft grafts and try to get very good cambium alignment on one side
Wrap over the graft union with parafilm and then wrap over it again with electrical tape as tight as possible without losing cambium alignment
Cover the entire scion and graft union with foil until it starts leafing out
Avoid touching or disturbing the grafted scion for as long as possible
Remove electrical tape after the scion has one foot of growth
Covering the entire scion with parafilm is an intriguing idea. I didn’t do that. I wonder if I can do it on cleft grafts after grafting. FWIW, I once tried a recommendation to coat the entire scion in paraffin wax. Didn’t work well at all. If I was going to add one thing to a list of “don’ts”, it would be not to get grafting wax or linseed oil anywhere the union, as it interferes with initial sap flow to the scion.
If you cover the entire scion and graft union with foil, how can you tell when it starts leafing out?
What if the scion doesn’t get one foot of growth in the first year?
You mention temperature. Are you referring to overnight? Here it still sometimes gets down to almost (and possibly below) frost at night, but today it was nearly 70F in the daytime. Is there some sort of master list of temperatures, and how do you measure them?
I’ve lately changed my thinking on temperature, but I then get a lot of failures, and I think climate gets overlooked a lot. We’re barely zone 3, and we get cold dry winds. Plums aren’t common here, especially not grafted ones, so I pretty much stick to apples. This year I collected scions as late as I could before the buds started to swell (so I didn’t have to store them too long), and waited until the sap was flowing well, as in starting to leaf out, before grafting. Did I screw up?
I’d love it if folks could work together to maybe contribute to a master checklist…
Like @dimitri_7a said, the way that works for one may not work for others due to several variables such as a condition of a tree, scion wood, weather, etc. The more you graft, the better you will be good at it.
Your zone alone makes it challenging for field grafting. Here is one of many threads about grafting that may help.
I think a person has to mess up a few to learn when is to early to remove. Some wrappings can stay on until the scion is dormant and some are constricted and need immediate removal. Sometimes the scion needs support for a while. Tough love is about the only way to learn but I think more scions are lost due to early wrap removal.
It depends on what you used to wrap it. I use Temflex. I stretch it well before wrapping. That way, it is not too thick. It is very stretchy and biodegradable. I leave them on until it breaks down. It can be over a year.
If you wrap with a material that does not disintegrate well such as garden tape, you need to cut it by the fall so it tape won’t girdle the graft union.
Temflex can be stretched very thin, and I need to stretch it thinner when I use it. I think @Olpea cuts it lengthwise before wrapping, and he may even manage to overlap when wrapping.
I’m not familiar with Temflex. I just spent more than I wanted to on Parafilm, not in a hurry to throw it away now – seems pretty good, except that I think I used too many layers (learning, and I have a lot now).
How does Temflex compare to Parafilm?
I use parafilm to wrap all my scions as soon as I get them, and I leave it on when I graft. After pulling the graft snug with a grafting rubber or rubber band or temflex I cover the graft with parafilm, being sure to wrap far enough up the scion to cover the joint, but not so far that I work the scion free from the graft - that’s the main reason I like to wrap the scion before I graft. @barkslip mixes parrafin and mineral oil, irrc, and dips his scions. But then, he does them by the hundreds, at least, and I do a dozen here and there.
If I have any doubt about how well I’ve covered with parafilm I dab a little johnny wax over the questionable spots.
Some of the others use a product that you don’t need to remove. I use parafilm and snug it tight with the cheap plastic electric tape. I like to remove or at least put a relief slit in the tape before winter.
I use the Temflex and I split it lengthwise also. When it is stretched it is probably no wider than the rubbers but I do slightly over lap it. It will split with scion growth and doesn’t girdle. In fact buds will break through it. It also adheres a bit to the parafilm so on the ones that I have removed in the fall it all comes off in one layer. It’s sold at Lowe’s for less than $3 a roll and one roll lasts a long time especially if you split it. I attempted to order it on amazon and it was almost $7 there so don’t try to get it that way. I wrap my scion with parafilm and then wrap the graft union good with parafilm. I put the Temflex over the top to pull it tight and strengthen the support. When I first started grafting (and it hasn’t been that long ago…) I played around with what I used but I’m pretty comfortable now and wrap everything the same way.
I actually used something very much like Temflex on these grafts that failed. Should have removed it before fall I guess.
This is my first time with parafilm, it seems to stick to itself pretty well. But I think I might try to remove some, as I wrapped multiple layers.
Occurs to me parafilm might make a decent frost burn/sunscald protection for young grafts over winter, to protect them from desiccation — our winters here tend to be cold and dry, and then Chinooks blow in to warm above freezing and are even drier.
My apple graft failed this morning. It has been lush for several months, but we had strong gusts this morning out of nowhere and the scion snapped off. Amazingly the cleft graft is still intact with the wedge from the scion still wedged in there. So the graft union itself is still intact, but the scion wood broke. There’s not much left in the graft for it to grow new wood.
What can I do with my remaining scion wood that is now sitting in a cup of water? Should I try to regraft? It’s a splendour apple scion that I’ve been dying to grow and was frankly very disappointed this morning.
My thinking is that I have nothing to lose at this point by retrying. Any suggestions on how to approach this during non dormant season?
That’s right Mark. And just as Kathryn mentions, it’s about the same width as budding rubbers after I cut it longways and stretch it.
As mentioned, it’s just for wrapping the graft union, or for closing T-buds when I bud. I don’t wrap the Temflex over the bud itself, but everywhere around the bud to hold the flap closed. Then I put the parafilm over that.
I’ve tried a rubber tape similar to Temflex, but I liked the Temflex quite a bit better, so from then on, I’ve just stuck with Temflex rubber tape.
I can’t seem to find the Temflex at any of the big box stores around here (they all carry cheaper rubber tape) so I’ve had to resort to ordering Temflex online. Just about a month ago, I ordered 3 more rolls of it from Amazon. I’m done grafting for this spring, but I was getting low on the Temflex, so I ordered some more.
I don’t put it over the scion bud either. I just use parafilm over those buds. But lots of times if the rootstock has a bud that wants to grow it will come through the Temflex. It’s amazing the strength of plants.
