Thanks for the advice! Please let me know how your pears go!
I’ve done some internet research, and typically what I read was that the bark grafts had to be done when the bark is slipping but before it got too warm out (around 50-60 degrees Fahrenheit), and that the chip buds could be done when it is warmer (around 70-80 degrees Fahrenheit). But I didn’t find anything that said whether or not the chip buds could be also done earlier, when it is only 50-60 degrees out. Which is why I got confused!
As an FYI, I’ll be using this tutorial for the chip buds Mega Chip Grafting Demonstration - Guides - Growing Fruit, if that makes any difference about timing/temperature?
