Chris, et. al.-
What time of year do you start your grafting? Gary Wood & Mike Hagedorn recommend fall (locally defined as "when the leaves fall off your maple trees" by Gary), specifically discussing grafting black pine onto ponderosa. Obviously green house environment through the winter is required. What is recommended for your area(s)?
I have had success 2 times a year. One is dead of summer (read dog days of August here in Florida) and the other is late winter when we actually get our coldest days (early ish February).
I'm guessing on this part -> but I believe I may have success most of the year in Florida as long as I can keep stuff in mostly shade and under a good mist to keep the tender bits from drying. I never wrap or tent the bud. As Chris pointed out I would aim to get off the bus one stop before the candles begin to change and harvest scion then.
I too have a frankenstein tree I have been planning for uncountable grafts in as many methods as I can find. I must try the thread graft as Tom illustrated.
Also - anyone ever try a grafting chisel? I picked one up for use and in theory it looks pretty cool. Fragile but cool.
Thanks all!
