my sweet peas are about one foot high in green house, when can i plant out side please

[mumofstig]

I'd move them outside, to somewhere sheltered to harden them off, first.
Mine are the same, there have been too many cloudy days for a while

Haven't even sown mine yet! Must do it tomorrow.

Just sowed ours yesterday.  We got frost in June last year so I'm nervous about planting anything too soon.

Our's are just showing, and we have some new and old (last year's) seed on the go. They're in the GH in trays of compost, and hopefully thinking it's about time to get going...

A year without sweet peas is just not worth thinking about..:0(

My sweet peas have been out for a few weeks and have doubled in size already.
I sow them in pots in the greenhouse early January and normally put them outside when they are about four to five inches high, just the time when they are trying to find something to cling onto with new tendrils.

We rarely get frosts here and if we do they are very light ones.
But, I always thought sweet peas were a hardy annual and did not suffer from frosts.

They are hardy, but if you sow and grow them on under glass, they won't survive frost just after planting out. That's why the need to be gradually hardened off.
