What's the issue you encountered?

When breaking a redwood tree, I noticed there was podzol underneath instead of dirt

How can the issue be reproduced?

Find a naturally generated redwood forest, and it probably works by growing one too

Closing this since it's not actually a bug. The trees in the vanilla Old Growth Taiga also don't replace the podzol with dirt.
