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
the scion on the second wrap thus holding it in alignment. Don't be
pulling the rubber too tight. But be prepared to cut the band after it
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
nearly as important as walnut & pecan.
As for storing the Parafilm in the frig, a 250 foot roll can last for
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
quickly refrigeration isn't necessary.
