When is the Best Time to Find Chaga

Search for chaga during late summer to early autumn, when the temperatures start to drop. This period provides optimal conditions for chaga to surface on tree bark.

What are Some Tips for Finding Chaga

Look for chaga on the trunks of living or dead birch trees, focusing on tree wounds or damaged areas.
Scan for black, charred-looking growths, indicative of chaga, primarily on the outer bark.
Examine recently fallen or dead birch trees, as chaga continues to grow post tree death.
Explore wooded areas with high birch tree populations, as chaga is more likely to be found there.
Use binoculars to check higher parts of birch trees, as chaga can grow out of the direct line of sight.
