Late 2018 I took some seeds from an artichoke plant, sowed a few early in 2019 and planted one out.  It's become this monster, 1.8m high and 3.1m wide, with about 100 small heads.  What should I do to enable a good crop for eating?

Sorry, but that looks like a Cardoon, rather than a Globe Artichoke. They do grow very large, like yours has.
