Please note I will be redoing the syllabus today and tomorrow and expect to have a new order of business posted before class this weekend.
Sorry for the inconvenience - but we will get this figured out. We might have the chance to do a field trip to a grafted orchard in Malibu. Do you, as the ones who will go on that field trip, have any thoughts about this? It is a property owned by the man who demonstrated grafting
Saddle Graft
Saddle grafting is a relatively easy
technique to learn and once mastered can be performed quite rapidly.
The stock may be either field-grown or potted. Both rootstock and
scion should be the same diameter. For best results, use saddle
grafting on dormant stock in mid- to late winter. Stock should not be
more than 1 inch in diameter.
Preparing the Stock
Using two opposing upward strokes of
the grafting knife, sever the top from the rootstock. The resulting
cut should resemble an inverted V, with the surface of the cuts
ranging from 1/2 to 1 inch long.
Preparing the Scion
Now reverse the technique to prepare
the base of the scion. These cuts on the rootstock and scion must be
the same length and have the same slope so that a maximum amount of
cambial tissue will make contact when the two halves are joined.
Inserting the Scion
Place the V-notched scion onto the
saddle of the rootstock. If rootstock and scion are the same
diameter, cambial alignment is easier; otherwise adjust as needed.
Securing the Graft
Wrap the graft securely to keep it in
place, being certain it is well sealed from air by using wax or other
materials.
