Rhubarb going to seed

I cut the stem off but im a newbie to this growing stuff so i bet thats the wrong way lol 

Yes, cut the flowers off as soon as you notice them but if you can leave them to grow-on a bit they are lovely in big flower arrangements So if you only have one plant cut them off early, if you have a huge patch leave a few to put in a vase.

It seems no matter what the weather, rhubarb always wants to go to seed. So as already said, pull out the whole seeding stalk or it will keep sending up more flower shoots from that same stalk. They're pretty but they do limit the amount of edible stalks you get.
