What's happened to my sweet peas?

[AutisticLegoLover]

I've kept them inside because it's too early to plant them out. They were really healthy looking then suddenly look like this. The other 2 pots are looking less healthy now too. Should I repot in their big plant pot but keep inside? The house is on the cool side.

They are very hardy and may well be too hot, I would get them outside in a cold frame or sheltered spot. Mine are doing fine in an unheated greenhouse.

Maybe a spot of water if they have dried out.

I would have a look at the roots. Sweet peas have a long root system, so I guess they need space. I would personally repot them and put them somewhere protected cool and light.

I've put them in a nice big pot outside for now but might bring it inside once it goes cold later. They were lovely and healthy at first so I'm not sure what's caused the wilting. Hopefully they will recover.

I would guess they are too warm. Mine are planted out now and very happily survived the last two frosts
