What is the best way to havest rhubarb

I find the best way to harvest rhubarb is: hold the stalk (flat hand) close to the ground (about 3/4 of the way down) -- push the stalk sideways and backwards (45 degree angle out away from the plant) -- once you hear the snap, grab the stalk twist and pull simultaneously.

Hold the stem close to the ground and twist gently as you pull it up

What variety of rhubarb is best to grow as a perennial in zone 7. I tried rhubarb about 45 years ago and was unsuccessful. Reason being that the temperature in the winter wasn't cold enough in the winter and if you were to try to grow it you were required to expose the bulb (?roots) to a freeze. Are there new varieties that don't require that. Please advise.

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.

It says to remove the flowerstalk but no mention why there is a flowerstalk.. I was suprised today to find a stalk at least a meter high?? WHY....???

My Month by Month Florida Gardening book says you can grow rhubarb year-round in north Florida and August to October in central and south Florida. I’m guessing shade cloth would be in order for the latter two the rest of the year. I never cared much for it growing up in Iowa but I think I’ll give it a try at my little hobby farm near Arcadia, Fl just for the challenge of it.
