A separate texture, unless you're on a limited budget, would work fine. Small modular rocks as a separate asset from the beams would work imo. Combine several of them in small clusters that would look nice at the base. Then just rearrange them and use them as ground break up or as transitions near other assets.

So you would even add real geometry into those corners to hide those seams where logs meet vertical beams? I thought that I would only paint dirt into albedo..
