sweet peas

What do you grow them up? This year, my husband made me a tall wooden obelisk which gave my sweet peas lots of room to grow upwards - and they all had long stems! I don't know if this is the answer, but it has worked really well and I've never had such good sweet peas before!

Iv had some Lovely Flowers 2 on my Sweetpeas ,Mine were grown up a Cane Trellis this yr&a Wigwam id made 4 them from Laural Branches:) Do/Did u feed them on regular Basis ? Their very Hungry Plants

Are you especially growing the long stemmed variety?
I have grown long and short stemmed, my favourite is actually a short stemmed called `cupanni` wich is two-tone purple and has a lovely perfume.

Thanks for all your answers I think perhaps I was not feeding them enough
