I actually have a couple of questions.
This was my first year grafting and I grafted 10 different kinds of pears (3 euro and 7 japanese) with three grafts each for a total of 30 grafts on OHxF 97. I also grafted 20 different kinds of apples on B118 with three grafts each for a total of 60 grafts. I grafted everything on April 1 and about a week later a couple of the pears had started to break dormancy. The following week several more pears and a few apples broke dormancy. About three weeks after grafting almost everything had 'woken up'. It appears that I have lost 1 pear and I think 2 maybe three apple grafts (not sure what happened but being my first time I guess it could be almost anything). I did a few cleft grafts but mostly whip and tongue then to seal the graft I used some green gardeners tape (not really tape in my mind as it has no adhesive) that has some stretch to it but not much. I tied most everything pretty darn tight to bring everything in to contact. I then wrapped with parafilm.
My first question is can that green tape stay on all season or should I remove it soon? I have seen varying answers to this regarding other things such as rubber bands and the like that naturally fall off during the season. I don't see this green tape falling off on its own though. The last thing I want to do is strangle everything I grafted my first time out.
Secondly, over half of the apple grafts appear to be growing fairly vigorously with many of them having put on 10-12" or perhaps more. By comparison the pears are moving at a much slower pace having put on maybe 4-6" of growth. Is that just the difference in pears vs apples or rootstock or is that about normal?
Third, and I think last, is it ok to use some liquid fertilizer (Foliage Pro) on first year grafted trees? If so, is there a certain time after grafting for which one should wait?
