Transcript of Grafting, Budding, and Layering

Grafting Grafting is a process by which two different plants are united so that they grow as one. The scion is the newly installed shoot, or the top of the plant. The rootstock (or stock) is the seedling or plant that is used as the bottom half of the graft. How it works The scion and rootstock form a physical union, which is the growing together of tissue.

This process allows the plant sap to move across the graft, from the rootstock to the new top, then back again. Types of Grafting Whip (Tongue) Grafting is used mainly for fruit trees and is done in the winter months Side Veneer Grafting is the most effective way to graft evergreens. This is done in the early spring. Cleft Grafting is used for topworking trees, or when the rootstalk is bigger than the scion. This process is also done in the early spring. Grafting is used to increased the number of a desirable plant and give them stronger with roots that are more resistant to diseases. Grafting is used to: Topwork a large tree

Graft a different variety to many limbs of the tree

Insert a different variety on part of the limbs for cross-pollination

To propagate plants that may be difficult to bud. The two plants must be related closely enough that the stock and scion can grow together

Grafting is done when the stock and scion are dormant (have no leaves) The cambium is the thin tissue just under the bark of the scion or stem The cambium layer of two matched parts must come in contact and held tightly together.
DON'T LET THE CAMBIUM DRY OUT! As soon as the graft is made, all cut surfaces need to be covered with waterproofing material.
(grafting wax, plastic ties, rubber ties) Match the growing area at the edge of root piece on at least one side Budding Most popular types of budding T-Budding is used for 1-2 year old seedlings, such as apples, pears, peaches, plums, cherries, citrus fruits, and roses. This works best in the late summer.

The rootstock must be actively growing to be able to do this. Chip Budding is used during the summer or fall and works best for grapes.

The rootstock does not need to be actively growing for this process. The cut that is made for the bud should be cut on the north side of the tree to protect the bud that you are placing in it from the sun in summer and winter Layering Layering is the method of asexual propagation where the roots are formed on a stem or root while still attached to parent plant. The Layer is the root or stem that is rooted and is cut free from the parent plant only after the rooting process has taken place. Layiering is easy to do but requires more time than the other forms of asexual reproduction. Less plants can be started from the parent plants than with using cuttings. Disadvantages to Layering Advantages to Layering Layering is more successful with which plants will root compared to the results of other methods Plants that are difficult to root when using other methods should be layered. Types of Layering Simple Layering is when a branch from a parent plant is bent to the ground and one end is partially covered with soil.

This process usually happens in early spring.

This will take watering and shade until the root system is established. Air Layering eliminates burying the part of the parent plant in the soil. Part of the plant stem will get slit and surrounded by moist growing medium in an enclosure.

This is normally done in the spring on wood from the previous year.

Older wood is more difficult to root. Grafting, Budding, and Layering Plants!!
