Should I pot my sprout up now ?

Wow Amy - that's amazing! Maybe it will grow into a giant sprout?! Please keep us informed of progress :-)

Amy, you are going backwards, sprouts will come on new plants sown in April, planted out in July, sprouts form by October.
I have seen this tried before, you can try and grow yours on, it MIGHT produce a flower from which you may get some seeds. I have to say I am very doubtful it will succeed, but good luck and let us know how it goes.

Where did you get the idea from, Amy? Fascinating experiment!

I did this years ago with my class of 8 year olds. If I remember correctly all of the sprouts eventually withered and died. In theory as said they should produce a set of yellow flowers.

Amy, you might be more lucky with a more immature sprout, this one looks to be too fully developed.

I potted it on this afternoon Dr Bob , I will let you know if anything interesting happens ........ thanks for the infomation .

Spritz it was a sprout that had been left in my veg . basket it looked as though it wanted to grow ,, I thought I would see what would happen , I like to experiment ,it was exciting to see it grow ...........

great sprout!

And why not, Amy! good for you...:-)
