Rhubarb is basically quite easy to grow, drought tolerant and pretty tolerant of a range of soil pH. It prefers slightly acid soil, but mine isn't and it does okay. Mostly it is plant and forget. Mine isn't thriving as well as it could because the location it is in is too shady (a chronic problem in my wooded lot). The rhubarb likes a lot of sun.
I have no idea where in the world "Hull" is, perhaps only revealing my ignorance. But rhubarb likes coolish growing areas, where it has at least 6 weeks of winter below 40 degrees (and it's quite tolerant of colder) and not too hot or dry in the summer. If I had to guess, I'm guessing you are in England, just because it seems to be usually the UK folks who think that putting up one word is sufficient locating.
If so, it should be perfect climate for it, cool moist summers.
Don't pick any the first year. It needs to get established first. And don't over pick the second year.
