The photo above shows two Kanza grafts made in the same field just 100 feet apart. The graft on the left is completely dead. You can see where I had tied the graft's new growth to a bamboo stake with blue fagging tape last summer. Now, the tree is pushing out trunk sprouts below the graft union in an effort to grow a new top. Note the reddish color of the foliage. This tells me that all new shoots are coming from the seedling rootstock. I'll let this tree grow out this year and place another Kanza scion on the tree in 2015.
The healthy tree (above, right) has already developed numerous new Kanza shoots. The only problem is that this tree has developed a 'lolly-pop' appearance--all the new shoots are clustered at the top of last summers new growth. This growth pattern is common for open grown pecan trees and is one of the major causes of poor tree structure. During this time of year I like to practice a little directive pruning and follow the 2-foot rule for tree training.
Pruning out most of the 'lolly-pop' will also help stimulate growth from lateral buds further down the stem. In a couple of weeks, I should see buds breaking all along the trunk in areas that currently look bare. In training a young tree, my aim is to develop a well balanced tree with lateral branches growing out at regular intervals all along the trunk.
