For successful grafting to take place, the vascular cambium tissues of the stock and scion must be placed in contact with each other. Choose a rootstock and a scion that are close in size (for modified cleft graft) and cut the rootstock with a sharp pair of pruning shears about three inches from where the ground line will be on the tree.
What is the difference between scion and rootstock grafts?
In the world of grafting, there are many more scion varieties available than rootstock varieties. Rootstock varieties may come from naturally growing trees, unique naturally occurring plant mutations, or be genetically bred for the purpose of being rootstock.
What is scion grafting used for in trees?
It finds common use in tree nurseries, and particularly in topworking apple, pear, peach and apricot trees. As the scion is smaller, the process does take longer than other types of grafting simply because it takes longer for the limb to grow out of a single bud.
What happens to the rootstock of a grafted tree?
This process produces a tree that has same genetics of the scion but the root system of the rootstock. Sometimes grafted rootstocks can sucker and send out shoots that revert to the type of growth of the original tree. If these suckers are not cut off and removed, it can overtake the growth of the graft.
How do you graft a scion to a stock?
Insert the scion into the cleft with the narrow side of the scion toward the center of the stock (Photo 15). Gently remove the cleft grafting tool or screwdriver so the stock will close tightly on the scion. Extreme care must be taken to match the cambiums of the scion and stock.
When grafting is done which part of the plant is a clone the scion or the root stock?
In grafting, the upper part (scion) of one plant grows on the root system (rootstock) of another plant. In the budding process, a bud is taken from one plant and grown on another.
How do you graft scion and rootstock?
Insert a wedge of the scion wood into the cleft and bind with tape, grafting paint, or grafting wax. Over time, the tissues of the plants will grow together and form a successful graft union. Bridge grafting: This type of grafting is suitable for repairing woody perennials damaged at or near their base.
How is scion and stock selected in grafting process?
In most cases, one plant is selected for its roots and this is called the stock or rootstock. The other plant is selected for its stems, leaves, flowers, or fruits and is called the scion or cion. The scion contains the desired genes to be duplicated in future production by the stock/scion plant.
Where is the scion located when grafting?
The scion is typically the top part of the grafted plant. If it is inserted lower down on the plant during the grafting process, everything above the scion is usually cut off in the spring.

When to graft a scion?
Grafting includes budding and is usually done in winter or early spring with dormant scion wood. Budding is accomplished by inserting a mature single bud of the desired cultivar into the rootstock in contact with the cambium. This procedure is usually done during the late growing season (July, August, or early September), but it may be done at other times.
What is the part of a plant that is grafted?
It consists of a shoot with several dormant buds that will produce the new stem and branches. The rootstock is the part of a plant that becomes the root system of a grafted or budded tree. In order to be a successful graft or bud, the cambium layer of cells located on both plant parts must align and grow together. This cambium region is between the xylem and phloem and is where all new plant growth occurs.
Why Graft?
Reproduce vegetatively. Numerous selections of plants will not reproduce true from seeds or cannot be economically reproduced from vegetative cuttings (fruit varieties, flowering ornamentals, etc.).

What is grafting in plant propagation?
Grafting is a method of asexual plant propagation that joins plant parts from different plants together so they will heal and grow as one plant. This technique is used to propagate plants that do not root well from cuttings, to utilize superior root systems, or to maintain clonal production. Nursery workers and fruit tree producers must know how ...
Why are rootstock plants grafted onto rootstock?
While the importance of rootstock plants is mostly stressed in fruit crops, other plants are grafted onto rootstock to create specialty or ornamental trees. For example, a knockout rose shrub in tree form is not a naturally occurring tree or the result of pruning and training. It is created by grafting a shrub onto related rootstock. Even common trees such as maples are grafted onto specific maple rootstock plants to make better quality maple trees.
Why are rootstocks selected?
Rootstock plants are selected not only for their close relation to the desired plant, but also for the attributes it will give to the desired plant. In the world of grafting, there are many more scion varieties available than rootstock varieties.
Why Do We Use Rootstock for Trees?
Grafting onto rootstock that is already established allows young fruit trees to bear fruit earlier. Rootstock plants also determine the tree and root system size, fruit yield efficiency, longevity of the plant, resistance to pests and disease, cold hardiness, and the tree’s ability to adapt to soil types.
What is rootstock in plants?
Rootstock is the base and root portion of grafted plants. A scion, the flowering and/or fruiting part of the plant, is grafted onto rootstock for a variety of reasons. The scion and rootstock must be of closely related plant species in order for the graft to work. For example, in fruit trees, pitted fruit like cherry and plum can be rootstock ...

In eight years, the kids may be off to college or starting families of their own. For this reason, many gardeners choose to purchase immediately fruiting trees ...
Where do rootstocks come from?
Rootstock varieties may come from naturally growing trees, unique naturally occurring plant mutations, or be genetically bred for the purpose of being rootstock. When a successful rootstock plant is identified, it is then propagated asexually to create exact clones of it for use as future rootstock.
Can fruit trees be grafted onto rootstock?
Another benefit of grafting onto rootstock is that fruit trees that require a pollinator can actually be grafted onto the same rootstock as their required pollinator.
How to grow a scion tree?
Water and fertilize the grafts regularly to ensure quick growth. Keep the area around the grafts weed free so that there is little competition for needed nutrients. Your hope is that the scion and the root stock successfully unite and the roots begin to feed the scion. Small buds will emerge as other trees in your area begin to bud. To ensure that all of the growth goes into the scion, you should remove any suckers or small sprouts that emerge from the root stock. Leaving them will allow much needed nutrients to be taken from the scion.
What is tree grafting?
Tree grafting is a procedure where you take a piece of an existing tree (scion) and attach it to a receptive root stock and they form a new tree. You might refer to it as “tree surgery.”. It may sound complicated but it is actually quite simple and rewarding.
How to cut a scion?
Choose root stock and a scion that are close in size (for modified cleft graft) and cut the root stock with a sharp pair of pruning shears about 3 inches from where the ground line will be on the tree. Carefully split the root stock down the middle about 1 ½ inches. Make a wedge with the scion that comes to a blunt end and is equal in length to the depth of the wedge you cut in the root stock. Carefully insert the scion wedge into the split of the root stock. Closely inspect the two pieces to ensure that the outer cambium layers touch as much as possible. Continue whittling the scion end and inspecting it until a clean and solid match is made. Don’t rush this step because the entire process depends on good contact between the scion and root stock.
What is the best rootstock for a nativ nursery?
Nativ Nurseries also offers crabapple, persimmon, and pear that make excellent rootstocks. To make clean cuts you will need a sharp pair of pruning shears to remove the scion (the part of the tree you intend to graft). A razor sharp knife that can trim the scion and root stock is essential.

Why do grafted trees revert back to rootstock?
There are various reasons for a reversion in trees grafted. For instance, grafted trees respond to severe pruning by sprouting from below the graft and reverting back to the rootstock. Rejection of the grafted scion (original grafting tree branches) can also occur. Rejection often occurs when grafted trees are not similar.
How Does Tree Grafting Work?
Grafting trees begin with healthy rootstock, which should be at least a few years old with a firm, straight trunk. You must then find another tree, which can bear the fruit, referred to as the scion. Scions are usually second year wood with good leaf buds and about ¼ to ½ inch (0.6 to 1.27 cm.) in diameter. It is important that this tree be closely related to the rootstock tree.
How to prevent rootstock from taking over?
The best way to prevent the rootstock from taking over is to remove any new sucker growth that appears below the graft line. If the graft line goes below the ground, the tree may revert to its rootstock through suckers and give the wrong fruit. There are various reasons for a reversion in trees grafted. For instance, grafted trees respond ...
What happens to the top growth of a tree when the graft is removed?
At this time all the top growth (from rootstock) above the graft is removed so that the grafted branch (scion) becomes the new trunk. This process produces a tree that has same genetics of the scion but the root system of the rootstock.
How big is a scion tree?
Scions are usually second year wood with good leaf buds and about ¼ to ½ inch (0.6 to 1.27 cm.) in diameter. It is important that this tree be closely related to the rootstock tree.
What is tree grafting?
Tree grafting is an excellent way to bring the best of two varieties together into a single tree. Grafting trees is a practice that has been done by farmers and gardeners for hundreds of years, but the method is not fool proof. Sometimes grafted trees can revert to their original form.
Can scion trees die?
Sometimes scion branches on grafted trees simply die , and the rootstock is free to regrow.
How to attach a scion to a rootstock?
To attach the scion and rootstock together, a horticulturalist makes a clean, usually notched cut in each piece and secures them together. If all goes well, the two partial plants will grow together into one whole. It’s actually very similar to the way an organ transplant works: just as a heart can be removed from one body to go on beating in another, the rootstock and scion each recognize the other as a missing part that can replace the one they were removed from.

Trees with this rootstock are also very productive for their size, and start producing early in their lives. They are perfect for city gardens, decks, or even patios! Keep in mind that trees grown on this rootstock will need more water, mulch, and staking than those with larger root systems.
What is the above ground part of a grafted tree called?
The above-ground part of a grafted tree, aka the part that makes tasty fruit, is called a scion. The scion determines what kind of fruit the grafted plant will produce. In other words, it’s what makes a ‘Granny Smith’ apple a ‘Granny Smith’ and a ‘Bartlett’ pear a ‘Bartlett.’. Scions are made by cutting young shoots from an established tree.
