Moisture Inside Parafilm Wrapped Scion

[behlgarden]

I have tightly wrapped scions with Parafilm and yet I see moisture inside the parafilm. Also on 1" and thicker root scock where I top worked the trees for cleft or bark grafts, I see moistiure underneath the film. I am 100% sure its not the outside moisture but moisture coming from the tree itself.

Thoughts?

Leaf it alone!

I see that on most of mine right now also.  Don't think there is anything we can do about it.  PJ's advice is probably best.

But...can this cause/promote issues...such as causing mold/rot to spread more quickly?

Jay usually when you see moisture under the film it is because the film as lost its unique Permeability Characteristics. At this point you can't do anything but wait and hope!

Parafilm M Shelf life:
Three years without deterioration if stored between 7°C and 32°C and at 50% relative humidity

Good Luck!

Also protect your grafts from direct sun or excessive heat!

It happened to one of my Guava grafts where mold started to grow and rotted the graft, even though the union and 1" of scion from Unit was nice green but mold was spreading faster than graft could push. still looking for ways to prevent this moisture issue. specially in thinner scions, its very difficult to wrap the scion tight.

i nearly always see little mositure bubbles inside my parafilm grafts but it doesnt seem to cause any major damage as I have a pretty high graft success rate

Thanks Lycheeluva, I will patiently watch.

Temps here aging went to 80 plus on Suday and dropped down to low 60's. big temp variation may be causing scions to lose moisture.

I actually saw a video on mango grafting on youtube and the guy recommended wrapping all scions before grafting, this eliminates the unnecessary pressure you put on scion when trying to wrap after the graft and it also ensures tighter wrap thereby may eliminate moisture issues. May be most already do it this way, I was wrapping the scion after grafting. hereon, I will wrap the scion before proceeding with the graft, after graft, I will simply wrap the union and seal
