Tricia explains the easy way to graft a fruit tree. Think creatively about how many kinds of fruit to graft on one tree.
 
   

Did you ever plant a fruit tree and then find out it wouldn’t produce in your climate? Did you wish you could wave a magic wand and make the tree change into a different one? Well, you can—but you have to wave a grafting knife instead of a magic wand.

You can add different cultivars of apples to an existing apple tree, for instance, for a multi-graft apple tree. Or if you have a healthy plum tree that’s not producing you can graft on another plum cultivar that is better suited to your climate. Do you want many kinds of fruit on one tree? Your best bet for that is adding several cultivars of stone fruits to one stone fruit tree.

**Don’t graft any patented fruit trees though. We know the Zaiger family in California’s Central Valley spends many years trying out and perfecting fruit tree hybrids. They go down many roads that lead to dead-ends so they need to have their successful fruit tree patents respected for their full 20 years. No GMO stuff, just old-fashioned plant breeding. Here’s a short video about the Zaigers.**

Budding is the name of the simplest grafting process, with the highest success rate. Tricia shows you T-budding (the easiest budding method) in our latest video, and we’ll walk you through the steps right here.

How to talk like a budding horticulturist

Let’s get our terms straight, as suggested by the University of Florida.

Rootstock: The roots and lower trunk of a tree. A rootstock is usually chosen for vigor and health. The scion is grafted on to the rootstock.

Scion: The scion is the upper part of the tree, including branches and leaves. Scions are selected for excellent fruit.

Grafting: The process of cutting a section from the scion and inserting it into another tree’s rootstock or scion.

Budding: The smallest scion section is cut for grafting—only one bud as opposed to a branch with several buds—and attached to another tree’s rootstock or scion.

T-budding: The easiest method of budding.

T-budding basics

*  T-budding works on trees younger than five with branches smaller than 1/2”.

*  T-budding is the preferred grafting method with stone fruits (peaches, plums, apricots—any tree fruit with a pit), and is also effective with pome fruits (apples and pears), citrus, and avocados. Here’s an exhaustive chart showing which fruits can be T-budded (and in which seasons).

*  Things you’ll need: a grafting knife and grafting tape.

*  Inverted T-budding, where the T is upside down, is the most successful way to do T-budding.

Using the inverted T-budding method on tree branches

For grafting on a branch, budding should be done on a spot that is 12” to 18” out the branch from the trunk.

Remove leaves and branches from the spot so you will have a clean, smooth working surface.

Make the T cut on the host branch by inserting your grafting knife through the bark, into the branch until you meet resistance of the wood layer of the stem. Cut an upside-down T with a vertical slit 1” to 1 1⁄2” long and a top slit up to 1⁄2” long. Open the slit enough to insert the bud shield that you will cut from the budstick.

Once you have your budding location selected cut some budsticks from your donor cultivar. This should be done in the morning when the tree’s turgor pressure is highest.

You want a nice healthy shoot with plump buds from the current season’s growth. The middle buds are the best so you cut off and discard the top buds and the bottom buds. Cut off the leaves, but leave about half an inch of the petiole to use as a handle when budding.

Using your grafting knife, start your cut 1/2” to 3/4” below the bud and end it 1/2” to 3/4” above the bud. It is critical that the back of the bud shield be straight or else it won’t take. Getting it straight and not slightly curved takes practice.

The bud shield needs to be inserted immediately into the T before it dries out. Slide the shield under the bark until it roughly in the center of the vertical cut. Make sure that you insert it right side up, buds put in upside down rarely take.

Using grafting tape, start below the bud for inverted T and above the T for a right-side up T bud to make sure the pressure of the tape doesn’t pop the bud shield out. Make sure you don’t cover up the bud though, leave that peeking out between the wrapping.

Check back a week to ten days later to see if the bud has taken. If the shield looks healthy and plump and the leaf petioles have fallen off then it has taken. If it looks all dry and shriveled the union was unsuccessful.

The bud won’t sprout this year. Next spring right before bud break cut off the wood above your sucessful budding and be alert to pinch off all other shoots in the area except your new bud. Marking it with some paint can help.

We have a French prune tree up on our mountain property and a Santa Rosa at our house in the Sacto Valley. We would like to graft a bud from the Santa Rosa onto the French prune, but you said the graft must be done immediately! If we kept the graft moist, and placed the graft within 1-1/2 hours (that’s how long it takes us to get from our valley to our mountain property) do you think it might still take? Also, can we do two grafts of the Santa Rosa onto the French Prune - essentially making the tree a half and half? Thanks

Vickie, In the video (linked in the article) we show how to keep the bud sticks fresh for up to 3 days. The real problem you face is that grafting between two different kinds of plums. Santa Rosa is a Japanese plum and French Prune is a European plum. Here is a UC article about interspecies grafting http://ucanr.edu/sites/sacmg/files/115407.pdf by “the” fruit tree expert in California, Chuck Ingels. He points out that although one can graft the Japanese onto the European, doing it the other way around is not successful. So, you can graft your Santa Rosa onto your French Prune.
