Wedgle system question

[KzooGuy]

Can the wedgle direct inject system be used on white birch? I've used it on trees with thicker bark like oaks, walnuts, and maples successfully, but have a white birch that I'd like to treat and wonder if it is viable because the bark is much thinner.

Yes, you can use a wedgle on white birch. Keep in mind they do not compartmentalizations well and injection sites will most likely lead to decay.
What are you treating for?
