Sweet Peas Growing too much!
My sweet peas are thriving - I have put in 2m canes and lashed together shorter ones but some of the main stems are now threatening to outgrow these! Would it do any damage if I nipped out the bit where the tendrils grow? And when cutting the flowers, should I leave some of the stem or cut it as close as possible?

Hi Denno, I have been trimming some of mine back as they are growing like mad too, it doesn't seem to have done any damage, in fact I think it's made them grow more
We have a thread called Growing Sweet Peas, I'll try and put a link on and it might be a good ides to ask on there so our resident SP expert can answer 
I have been cutting my flowers off as close to the main stem as possible.
