Growing Rhubarb

Harvesting notes say do not harvest rhubarb until a year old ! So what does that mean ? ie if I buy plants from garden centre I’m guessing already a year old ??? Maybe . Or does it mean once a crown is planted in my garden leave for first year . I have planted crowns given to me but didn’t do well so have moved ... now looking better , I have a variety of plants from garden centres , markets etc . I’m confused as too what year I can start harvesting. Some of it this season we hope ... how will we know . ?

I have not seen rhubarb growing for 50+ years but I would guess it depends on the size of the crown and how fat/big and healthy the stalks/crown looks. I bought asparagus crowns - about 50mm diameter - how old probably 6-9 mths. I grew some from seed and at 12 mths they were 150mm dia. Judge by how good the plant looks.
