make a bark graft. By May, the buds on the scion were bursting with growth. Then in June, I selected the strongest growing bud to become the central leader and later that same month I pruned off stalked buds. Now its mid July and I'm back again (graft in photo at right) for some more graft maintenance.
The graft has continued to grow in height but has begun to slow down in response to this summer's dry weather. With a slower rate of growth, the newest part of the shoot is not producing stalked buds. However, I did take the time to add another tie to attach the graft to the 2x2 post.
bacterial wetwood starting the decay process on the stump of the stock. Opening up the wound to the air will dry up this wetwood and slow the decay process.
The second thing I noticed was that callus tissue has formed all the way around the outside ring of the stock, a sign of healthy growth. I also noticed that lenticels on portions of the bark that had been covered by plastic were expanded (lenticels are raised rough patches in the bark that allow stems to "breath").
I have used tree marking paint in the past and found that it fades rather quickly. This is probably not a problem in terms of providing sun protection for the rest of this summer but if you would like to have a more permanent marker of graft location, latex house paint will give you 3-5 years of service.
