Last Years Grafting Attempts

In May, 2016, I attempted to graft pecan scion wood onto pecan seedlings using various grafting methods. In the following picture the failed arrowhead graft is enclosed in green grafting tape – note that a limb on the left side of the stock below the graft has grown about five feet high since the graft attempt.

The following two pictures show the back with the staples and front of the failed graft after it was cut off. One flaw noted in the second picture is that the scion wood does not sit down snug to the stock.

The following picture show an arrowhead graft that started growing and then broke off.   Although it was tied up to a supporting stake, apparently a bird landed on the top and broke out the graft union.

The following three pictures show a successful arrowhead graft with the bamboo support pole beside it. Note that the wood has callused completely over the staples and is starting to cover the top of the cut off stock.

The following two pictures show a successful 3-flap graft. Note that the diameter at the graft union is larger than the stock.

The following two pictures show another successful 3-flap graft. The top of the scion wood was cut off to promote healing. Note how large that the graft union and the short piece of scion wood below the cut off have grown. You can see the new growth from the scion that starts on the right side of the scion. It grew about four feet high during last Summer.

The following picture shows a failed bark graft.

The following two pictures show a successful bark graft. Again, the callus growth covers the staples and is starting to cover the top of the stock.


In the following picture the bark graft has only started to callus over. There is green wood in the tiny piece of scion, but, the future does not look good.


After one of the bark grafts failed as shown in the following picture a limb grew out of the stock underneath the graft location. Note how it first grew down and then curved upwards. Although it grew about four feet high, I wonder what I should do with it.
