Another Flat Grafting in Pictures
This is yet another depiction of flat grafting, done on 28 May 2000.
The stock plant is an Echinopsis (left), while the graft is a Rebutia (or possibly a Sulcorebutia) offset (right). Always select healthy stocks.
The stock plant is cut and the edges beveled (left). Make sure you cut enough of the stock plant so that the vascular bundles are visible. The vascular tissue can just be discerned in the picture. The surface is moist and the plant is firm and juicy, which means it is healthy. Use a razor to slice the plant tissue cleanly; never crush plant tissue near the surfaces to be joined.
The graft is then cut to expose the tissue where the joint is to be made (right). The vascular bundle is clearly visible in the picture. This tissue need to be aligned as close as possible between the stock and the graft for the operation to be successful.
The graft is then placed on top of the stock. Notice that there is ample room for shrinkage. If you do not bevel the edges of the stock plant, the shrinking tissue will cause the surface to bend into a convex shape, ruining the graft.
If the surfaces seem to be drying up, spray a bit of clean water on the surfaces to be joined. When joining the graft, though, make sure that air bubbles are pressed out.
The graft is then tied securely with rubber bands. Rubber bands are convenient if the plants are small. I haven't done any large grafts to I always use rubber bands to secure the graft. A long cactus spine is used (right) to hold the surfaces in place. Such spines are favoured by experts too. The rubber bands should be left in place until they break within a week or two. By that time, you should be able to tell whether the operation has been successful or not.
