Last spring, I Shimpaku grafted foliage in a Utah juniper (see “Grafting Utah Juniper”). While getting the right grafts is important, I have learned from experience that post-care is so important. Some simple takeaways – the bags are not opened too fast; open a little at a time; leave the tie at the base of single graft during the first year.
Getting the timing for opening the bags depends on the time of year when the graft and the speed with which the stem was growing. If the rod really takes off, that’s a sure sign that we can start opening the bag. Where you should open the bag? In the top corner! Creating an opening in the base of the bags lets out additional moisture and can lead to dried stems. After creating a small initial opening, continue to expand the opening every week or two until the bags are open.
In most cases, that’s all you need to do the first year. Unless the bonds that hold the stem to the host are severely reducing, I tend to keep them in place during the first year or more.
In the picture below, I had already created a small opening. Because the stem was well, I widened the opening.

Other graft was growing out of the bag. Continuing the process begun several weeks earlier, I opened the bag a little further.

I will continue to make room for new growth over the next month or two until all the bags are out of the way. Once I have a good sense of progress this year, then I can assess the need for additional grafts next year.
