It is the thin green layer just under the bark. This is the area of the tree that is actively growing. It is the vascular tissue of the plant. There are literally hundreds of fruit to taste; every kind of cherry, apricot, plum, nectarine, or peach you can imagine. Each time I visit, I keep notes of all the varieties I enjoyed, and I rank them with a star system.
There are a number of pome fruit orchards in the Santa Cruz mountains that also allow tasting of apples, pears, and quince. These events are open to the public and are held in January. Some grafts take well and seem ideally suited to my garden conditions; others never make it.
The fun part is annually tasting your way though the options and hunting for the attendant scions to try your hand at each one. Grafting—it turns out—is the easy part. The hard part is figuring out which varieties of fruit you want to grow! Guest blog author, Jesse Imbach, loves nothing more than perfect seasonal fruit. His modest home is taken over with experimental grafted trees and rare fruit varieties from around the world.

Basic Grafting Union Types — Bud Graft: This graft is performed late in the season, when the rootstock is growing, but uses a dormant bud, collected and stored in the winter. For example, one can easily graft one variety of apple onto another type of apple tree.
However, it is also possible to combine different fruits of the same genus. Some plants are even compatible with closely related species outside the genus; pears are sometimes grafted onto quince rootstocks, for example. At the bottom of this article, there is a chart that details some common fruit tree compatibility: Rootstock Compatibility Chart. There are many different types of grafting see links at end of article for more info , including:. Cleft grafting is a common technique used to change the variety of a tree or add a new variety onto an existing tree.
It is accomplished in late winter and involves inserting the desired plant branches into a cleft made in a limb or rootstock of another plant. Whip and tongue grafting is completed in late winter and fuses a branch from one desired variety onto a rootstock or existing branch of the same diameter. Bridge grafting is a technique used to repair damaged trees. It is performed by inserting new branches into the injured part of the tree and then letting the tree heal around them.
Bud grafting is a relatively easy technique that transplants a leaf bud from one tree to another. Although it may seem like an intimidating and technical process, it is really quite simple and requires only a few common tools. The rest of this article goes into the specifics of bud grafting and its benefits.
The pith is the colored, fleshy part of the branch that runs right through the center. Remove any existing leaf from the removed bud but keep the leaf stalk petiole. Peel back the bark and insert the new bud into the branch. Make sure the bud is oriented the same way on the new branch as it was on the old generally, pointing up!
If the bud takes, the bark and cambium layer of the host tree will heal around the new bud. If the bud withers and dies, it means that the graft did not take.
This will usually happen within a month. Just before the next growing season early spring , locate all places where bud grafts have successfully taken. Then, clip off the rootstock branch right above where the grafted bud was placed, as this will redirect the energy into the bud and allow it to grow quickly. That will secure the two trees together and that graft union will stay intact for the lifetime of the tree. So, in theory, you know at this point how grafting works. Let's go through the steps you need to take to graft a fruit tree.
Step 1. Collect scionwood in the winter. The cuttings are collected in the dormant season because this is when the plant stops growing and therefore requires far less energy. Step 2. Ensure the scionwood is disease and pest-free by visually inspecting it for any irregularities. Step 3. Label the scion with the name of the tree and the date of the cutting.
Step 4. Store scionwood safely. The cutting should be wrapped in a damp paper towel and then tucked into a plastic bag. Then place the package in the refrigerator until spring to maintain dormancy. Remove any fruit that is ripening in the refrigerator. Certain fruits produce ethylene as they ripen which can kill the scionwood.
Step 5. Preorder rootstock. Preorder early as rootstock sells out quickly. You may need to order up to 9 months in advance.
Step 6. In the spring, grafting fruit trees can begin. Look outside. If fruit trees in the neighbourhood have buds that are starting to open, you know that the tree's sap is beginning to flow. This is the perfect time for spring fruit tree grafting. Step 7. Use one of the grafting methods below. Check out some common methods for grafting fruit trees further down in this article. Once you have chosen a grafting method, you are all set, right? Well, that might not work for you. Rootstocks and scions that belong to the same botanical species are always compatible, so anything that is an apple, can be grafted to another apple.
Rootstocks and scions from different species in the same genus are also usually compatible. An example of this is within the genus Prunus or the stone fruit genus, which includes apricots, peaches, plums, nectarines, cherries and almonds. The Tree of 40 Fruits, which we talked about earlier, is an example of this compatibility. However, as you make your way up the taxonomic hierarchy from Species to Kingdom , the scion and rootstock become more incompatible because there is less similarity between the two.
You discover that they are in the same family. You think you have found a winning combination! But wait a minute When pear and quince are grafted, a toxin from the quince rootstock enters the pear scion and poisons the graft union, causing it to fail Pereira et al.
This is just one example of graft incompatibility and why it's important to graft rootstock and scionwood that are closely related.
So, getting the scionwood seems straight forward, right? Your best bet is to find a producer that specializes in growing clonal rootstock.
