when do you give up on something?

just an random question when do you normally give up on something that not working?

Depends what it is I suppose!

Depends in what respect

Bloody same here!   

i spent about £60 on these carrots got nothing to show for it!! i folow the book!!

Don't give up Steve!   

Could just be a late growing season due to the weather.

its doing my head in lee, i follow the book    

I thought my bonsai was dying this year even though I did everything right. It started to bloom a couple of days ago which is about a month late. So, still hope for your carrots.
