What is the best way to harvest rhubarb stalks-cut using a knife or twist and tear? Thanks

I sort of do a bend (push the stalk to the side - and I generally hear a snap) -- then I twist and pull. This gets the whole stalk out -- and sometimes some "white" (which is not edible and needs to be cut off). When I use a knife, I don't get the entire stalk out, which leaves a nub sticking out of the ground. So for me, it is the bend, twist and pull that works best.

Rhubarb produces a flowerstalk and flowers so that it can produce seed. all plants need to propagate. Rhubarb can be grown from seed, but first the seed has to be produced!

Best you google about it. Flowering is part of the life cycle of plants.

Where do you buy the rhizomes from in Western Australia Perth area? I have tried before to grow but with no success so going to try containers. Thank you. Faye
