ROOTED DIRT

Rooted Dirt is a Wandering Trader exclusive: no job villager buys or sells it at all, so the roaming merchant with the two llamas is the only source, at 1 emerald for 2.

No recipe in Java 26.2 produces it: it is gathered from the world rather than made.

The Wandering Trader sells Rooted Dirt for 1 emerald for 2. He does not buy rooted dirt back: that offer runs one way.

No standard villager profession lists Rooted Dirt in its trade table, so the trader above is the whole market for it.

He asks 1 emerald for 2, which works out at well under an emerald each, and 21 of the other 75 come cheaper. Price is the easy part: he draws his stock from a shared pool, so catching one that happens to be carrying rooted dirt is the real constraint.

The Wandering Trader asks 1 emerald for 2 rooted dirts. 8 of the 72 villagers that pay emeralds, emptied out:

a dark oak boat against 26 flint for the same 1 emerald, 26 times the carrying, and the shortest wait is the Butcher at 37.5 real seconds of shelf, gathering not counted.

The Wandering Trader is not part of any village. He arrives on his own near where you are playing, with two leashed trader llamas behind him, stays for roughly forty minutes to an hour, and then vanishes whether or not you traded with him. There is no workstation to place and no job block to break, so the usual tricks for steering a villager toward a particular offer do nothing.

He does not buy rooted dirt. He takes six kinds of item and this is not one of them, so the offer runs one way: emeralds out of your inventory, rooted dirt into it.

Each trader carries only a slice of the full stock list, so the one standing in front of you may simply not have rooted dirt today. If he does and you want more than one visit's worth, put a name tag on him: a named mob will not despawn, which turns a passing merchant into a permanent shop you can come back to.
