My grafts are growing! I came home from Calgary to find that almost all of my grafts had healed and were pushing new growth. Luckily they didn't get nipped during the recent cold snap. I lost 2 out of the 14-15 cleft grafts, which I think is a pretty good success rate (at least for me). Now all I have to do is keep them from freezing this winter. They're all in 3-gallon pots, so I can easily just move them into the garage if we get a hard freeze. So the results of my experiment seem to be pretty conclusive: You can dig up trifoliate and successfully cleft graft in the fall.
In running news, on Saturday I ran my last 20-miler before the marathon on December 8th. I ran it really fast, ticking off my last mile in under 8 minutes. I think I'm ready for the big race. I just have to keep from going nuts during the tapering phase over the next few weeks.
