What is a grafted cactus? It is two plants that have been joined together to create one plant. Both of the plants must be compatible to live with each other, otherwise the plant won’t survive as well as it should, or won’t survive at all.
There are many different reasons why you graft a cactus plant. It will help slower growing cactus, rare cactus, crested cactus, cactus that lack chlorophyll, or it increases the maturity of an existing cultivar for earlier fruit production. You can graft any cactus plant you want.
There are many different types of cacti grafting stocks you can use as rootstock. These are Acanthocereus sp, Cereus jamacaru, Cereus peruvianus, Harrisia jusbertii, Hylocereus undatus, Myrtillocactus geometrizans, Pereskiopsis spathulata, Selenicereus Grandiflorus, Stenocereus pruinosus, Trichocereus pachanoi and Trichocereus peruvianus
Grafted sulcorebutia rauschii The most common rootstock is Hylocereus undatus, often referred to as night-blooming cactus. These species have large, edible fruits, which are known as pitahayas or dragonfruits. They are a common plant you see in the nurseries, and the easiest to graft. Some collectors like using Mrytillocactus geometrizans because of it colour and strength.
Grafted plants that use this stock seem to last longer than Hylocereus undatus.
But they don’t last forever, either the rootstock can rot away, or the plant on top out-grows the rootstock. So, you will need to do some maintenance to keep your grafted cactus alive.
First, you need to remove any glue rocks if any are present in the pot you are planning to plant in, as they use this for transporting, but it will kill your plant, as it traps the water in.
Second, if the plant on top has overgrown, you need to support your rootstock or you can bury it but place rocks around the rootstock plant so the water drains away quickly, to make sure it does not cause rotting.
Third, if your rootstock plant dies from rotting or rotting appears, you will need to replace the rootstock.
Take note if you have a chlorophyll type of cactus; they won’t grow on their own roots and need to be grafted.
There are different methods to graft cactus plants too, but the main one used is healthy rootstock. Cut off the top off the plant, leaving about at least 12 cm left. You cut the sides off, leaving the core in the centre to make it easier to place. Cut the roots off the top plant and place both plant cores together. Using rubber bands, place it over both plants holding them together to make them seal. You don’t want air to get in between both plant as it won’t seal as one. You can use stockings to help hold the two plants together for 2 to 3 weeks as well before takes it off. Stockings allow air to flow, and water not to get trapped around the plant.
But if you don’t want to graft your own, you can buy grafted plants at many different places, or from me, as I will have many different types of grafted plants for sale soon.
