How to graft Lophophora
The materials to be used:-
• A Trichocereus to be used as the stock plant
• lophophora to be grafted onto the stock plant (this is called the scion)
• A sharp razor blade
• Methylated spirits
• Rubber bands
Sterilize the blade by dipping it into the methylated spirits (this must be done prior to every cut). Cut the top off the stock plant, this must be done with a single, clean cut. The stock plant should be a vigorous species (usually Trichocereus) and must be in full growth. The cut surface should be nice and juicy.
Chamfer the top of each of the ribs on the stock plant. This stops the cut surface from becoming hollow as it dries, causing the graft to be pulled apart.
Cut another very thin sliver from the stock plant. Leave the sliver in place on the top to protect the cut. This will ensure the upper surface is flat and remains clean until the graft is made.
Repeat the above process for the lophophora scion. Ensure the final cut is clear of any rotten material in a plant being salvaged. (The brown marks here are not rot, they are merely discolored parts of the plant).
Slide the thin slivers from both the stock plant and the lophophora scion. Gently press the lophophora scion onto the top of the stock and rub the cut surfaces gently together to ensure there is no air trapped between them.
When grafting lophophora , ensure the vascular bundle of stock and lophophora scion (the circle shown arrowed in the photograph) overlap in at least one place. If the two vascular bundles are significantly different in size, ensure they cross one-another. If they don't (even if the smaller one is completely contained within the larger one) the graft will fail.
Finally apply gentle pressure to keep the cut surfaces pressed together. The most usual way to do this - though it takes a little practice - is to use rubber bands. The lophophora plant should be put in a warm, dry place out of direct sunlight for a few days until the graft has taken and
