Hi Ron,

Here is an excerpt from the Nafex board on using Parafilm -




Now I use parafilm. It looks like it might be strong enough to bind the
graft, as well as protect it from evaporation, but it's not. Every
graft save
one bud graft that I tried that way has failed. But if I bind the
graft with
a rubber band and then wrap parafilm over it I've had good luck.


Ji Gina, etl,

Absolutely use a grafting rubber then cover. Even with whip & tongue it can
be difficult to keep the scion lined up perfectly with the understock. Lock
first the band on the understock then wrap upwards catching the very
bottom of
the scion on the second wrap thus holding it in alignment. Don't be
afraid of
pulling the rubber too tight. But be prepared to cut the band after it
takes to
prevent girdling.

Had someone call me the other day asking why his success rate was very low.
He was using masking tape only then covering with a plastic bag to hold in
moisture. It is very difficult to maintain alignment w/o the rubber.
Even a plain
old rubber band works, but must be cut later as they normally don't
deteriorate as fast. Proper alignment is vital, close only counts in
horseshoes and hand
grenades. There are always exceptions and one is apple. There alignment
isn't
nearly as important as walnut & pecan.

As for storing the Parafilm in the frig, a 250 foot roll can last for
years.
Over a long period of time, say two years, it can dry out along the edges
loosing it's elasticity. You are right, in the lab where a roll us used
up more
quickly refrigeration isn't necessary.
