Truffles can be cultivated, and regularly are. The catches are:
* They’re very picky about the environment they’re growing in which includes the soil, trees, etc. and that’s a lot of factors to cover. You can’t just build a greenhouse or just plant them wherever you are. Some places just won’t work.
* They take several years to develop, so you need to go through a ton of work and money to get set up and then you might find out 10 years later that they didn’t grow after all. Womp womp.
