Space the pieces of
tape so that they do not touch, for, if they do, they will be very
difficult to separate later. After they have dried for twenty-four
hours, wind the tape on pieces of cardboard about one foot square,
being careful not to overlap the tape. The tape is now ready for
field-work.
I want to mention some of the advantages I have found in using this
rubberized tape rather than raffia. The tape is uniform throughout and
is stronger than raffia. It does not fly around and frequently get
tangled as the latter does. There is no necessity for keeping it
slightly damp to be usable. It may easily be torn off at any convenient
length or it may be cut without injuring the edge of the grafting knife.
A last advantage is that it is self-sealing since it overlaps on itself
slightly when wound around a graft union. Because of this, there is no
necessity for painting the finished graft with melted wax as is
absolutely vital when using raffia. Personally, I use wax in addition to
the tape for I feel that it is probably safer with that extra
protection. Also it gives me an opportunity to wax over the tip end of
the scion when it is devoid of a terminal bud.
The only disadvantage in using tape is its cost which, I must admit, is
very much higher than that of raffia.
