Sod on the Hugelkultur beds

Perhaps I have missed it, as I am fairly new. I read somewhere that sod should be placed upside down on the hugelbeds, however in some of the pictures I have seen, it looks like it was placed right side up. Could someone help me with this please?

Thanks!

possibly the sod was an invasive species, such as quackgrass...and if you put that in a hugel bed it will grow into it's own grassy top..very quickly, as it is spread by bits of runners ..stolens..left in the soil.

the sod you put upside down would be best to be an annual type of grass or something that doesn't grow by stolens or runners..

I put a thick layer of sod roots side up and then another thick row with grass up on top of that. I didn't want to wait for two years, and I think this is enough soil medium to start the roots of the blueberry bushes and woodland strawberrys I plan to plant. Plus, I am sodding out another garden plot - so I have more than I need!

I'd double up on Brenda's comments and learn to identify rhizomatous grass and plan accordingly, as this is likely more important than grass-side-up/grass-side-down If not rhizomatous, than upside down may reduce regrowth if your soil layer is shallow. If rhizomatous than I put it under the wood.
