What is Grafting?
Grafting cacti and succulent by joining two cacti or succulent pieces of stem together to form a plant. By doing this you create a new plant. Grafting can be used for rescuing a weak or dying plant and also to speed up the process, even for variegated plants, but sometimes by as much as a year or two.
There are many different types of grafting cacti and succulent stocks you can use, and some are easier than others. The only thing to remember is that matches in the cores are the secret. Because the top plant isn’t getting nutrients won’t survive. A sharp knife or razor blade needs to be sterilized before use. Join the plants quickly with slight pressure to force out air bubbles and that might cause the cut surfaces to dry. There are several items to secure with like strings, rubber bands stretched over and also under the grafted plant, toothpicks, or even spines from any cactus plant. Placed it into a dry and out of the direct sun for two to four weeks until the scion does not move when it is pressed lightly. This indicates that the graft has begun to grow together.
There are five basic methods I know.
The Flat Grafts
Taking grafting plants slicing straight across, placing one on top of each other.
The seedling Grafts
To speed the process of the growth of a seedling.
The Splice Grafts
Cutting the plants at a 45-degree angle and joining them together with a toothpick or cactus spine.
The Cleft Grafts
Cutting a split, a making V shape in your rootstock. Trailing cactus used
The Stab Grafts
Like Cleft graft but wedging the top plant in the cut. Trailing cactus used.
There are many different grafting stocks you can use, like Acanthocereus Pentagonus, Selenicereus Pteranthus, Pereskiopsis Gatesii, Cereus peruvianus, Selenicereus Macdonaldiae, Hylocereus Guatamalensis, Harrisia Jusbertii,
Common ones are used the most. Hylocereus Undatus, Trichocereus pasacana, Myrtillocactus geometrizans, Cereus Peruvianus. Adenium species produce different colors.
Do take note, Maintenance is required. As some species only live for several years. So you will need to regraft to save the top of the plant.
