What I can find this?
have a question. Where and how often do you get your green materials? Do you cut down a whole birch every time you want to carve a spoon, or how do you do it?
I always seem to end up carving in half dried birch or what’s even worse - 3 years old material coz that’s what I can find.
If it is done correctly and at the right time of year:
"Excessive pruning (greater than 25 percent of the live canopy) should always be avoided. Heavy pruning increases light penetration to the root zone and can increase soil temperatures and reduce soil moisture levels. Pruning of birch trees should NOT be done between May 1 and August 1. This is the flight period of the bronze birch borer, and it has been shown that female birch borers are attracted to fresh pruning wounds. If pruning must be done during this time period, treat the wound with a registered insecticide. Wound dressings should not be used since they are not effective at repelling borers and do not promote closing of wounds."
