Hi Sylvain. If you use my method it is very sturdy. The rootstock will callous over and you will not have a problem. With the rootstock sliced in the center, it clamps the budstick very firmly. I would think if you cut a V in the rootstock it would not have as much support.

I use Lazz's method when cleft grafting. A key point Lazz brought out was to avoid making the cut in the rootstock too deep. Having the cut too deep will cause the wood to open up beyond the end of the scion and prevent the rootstock from clamping firmly onto the wedge at all points. Making it as close to the length of the V on the scion as possible will help make the rootstock to adhere to the scion at all points. Sometimes I wrap a number 64 rubber band (cut so that it has two free ends), around the graft, and tucked under itself, to apply additional pressure to the graft.

The wedge is never exactly the same on both sides, make sure the thicker side is to the outside edge of the rootstock, so that pressure is applied at that point.

One other item is that, in pushing the wedge of the scion into the rootstock, I think Lazz, and most grafters I know, stop before the cut is fully inserted. This leaves the little section of wood at the top of the scion (I think grafters have a name for this, but don't remember what it is) exposed, but helps ensure that all of the cut in the rootstock, and the perpendicular part of the scion are in contact. I guess cutting a V is ok, but it would be diffcult for me to get them both the same size, and the way Lazz does it works fine.

Ned, what do you mean by ...." outside edge of the rootstock"...? Both sides of the rootstock would be an outside edge. - Millet (1,329-)

I don't know will be interesting my method for same body,but I use for cleft grafting TREAD SEAL TAPE.Like for me it's work good.
One month ago I did these cleft grafts.

OK, thanks Lazz. - Millet (1,329-)

Viktor, Do you leave a couple half leaves on your scion when you do cleft grafts? It looks like that in the last picture. Also, I did not see the top of the scion wrapped.

I have done several grafts on to a Meyer lemon. The naval orange, key lime, ponderosa lemon, lemonquat, Moro blood orange, Satsuma, and Hamlin orange have all taken and are growing. I did try a seedless Lisbon lemon and that failed. I plan on trying a regular Lisbon lemon.

Viktor wrote:"Yes,I do. I left half leaves on the scions,but some leaves fallen.I don't use scion wrap because I use plastic bag.Before that I spread scion very thinly clear acrylic latex caulk.I don't know possibly this method is wrong ,but work."

I use that technique of leaving 2-4 half leaves when rooting most plants--I was told that it creates the same hormone that is used in Rootone and speeds rooting. I can see it being helpful with grafting if you are covering with a plastic bag to reduce moisture loss.

--I will have to give it a try.

Thanks, Laaz.

I ordered a roll - results of first attempt to come!
