Hi Nullroar,
I don't rightly recollect (to use a bit of western slang) what size I used four years ago, but I suspect they were on the small side. I just went out and looked at what's out there now, and the Prague has the unfortunate property that the newest branches are rather flat. From hat I just measured, the short dimension seems to be between 1/16 inch and 1/8 inch, while the wide dimension ranges from about 1/8 inch to 1/4 inch. That's about
3mm-6mm. I do recall I made two slices along opposite sides of the skinny side, forming a vee shape.
Another weird thing I just noticed (nothing to do with taking cuttins) is that it appears to be starting a second bloom, which I've never seen before this early. Maybe because almost no fruit set on the first bloom, due to the cold wet spring and early summer we've had this year.
