mulch

Got around 500Liters of mulch for my pots/ground. Cheap and reliable enough for years to come.

Just a bit bamboozled on how to mulch this setup. I’ll need to get crates later, but for now I’m trying to figure out the best way to mulch it properly. What mulch size should I aim for, and are there any other recommendations you would suggest? Thanks for reading.

I was on YouTube looking at some raised bed ideas as I plan to add a few in the spring.... Somehow, I spiralled down this rabbit hole of videos on how to fill beds and eventually onto some videos about biochar... All sorts of stuff about the benefits and how good it is to add to compost etc...
