is hard but using large braches should be easily, here on a gar http://www.youtube.com/watch?v=zJJNt7IUq6I
then wet with water and roots stim and cover with aluminum foil or try to use "mastice" for pruning...
i'm just able to do it on olive trees but with another tecnique and we do grafting in march, with low temps so the innesto is more hard to dry....
don't worry i'm just popping some corns
PS where is your 3aed on the rh that you had few times ago in your sign???
I guess grafting wooden stems (like the ones in the video) with a lot of lignin is way easier than green plants with soft stems.
Making the stem coincide could be not so hard, but for the following days after the work, the graft should be accurately keep in a optimal environment with high RH and right temps.
In the wooden plant there is not so much need to keep an optimal environment such with green plants due to their transpiration rate, slow in the wooden plants (like olive trees) and very fast in green plants that use water to keep an high cellular turgor and thus become hard, where a wooden plants use lignin.
Try to think about olives....their transpiration rate could be very low, they can survive without water for months in summer. Every plants is obviously different, but generally talking there is a lot of difference in plants with a lot of lignin and the ones with very few.
However.... I should give the coupling gap (innesto a spacco) a try and see what happen.
