I have a large pot of sweet peas which amazingly are still flowering (just!) If I cut them down to a bud about 6" high, could they over-winter and flower again next year? I ask this because they are usually completely dead by the end of August and it is so unusual to see them in November.
I know you can sow seeds in September to flower the following year so I wondered if these stems would shoot again if I keep them well mulched? Anyone tried this?
sweet pea plants are annuals so unlikely to survive over winter outdoors. It might work to pot some up and keep in a cool, not cold place with plenty of light.
Thanks woofgang, I thought that as you can sow them in September to flower the following year, you may be also be able to keep the roots going? but maybe if you sow them in the Autumn you have to keep them in a frost free place over winter?
Unlikely to survive the winter, unless you can move the pot into a conservatory or greenhouse. Sweet peas are only an annual in the uk. Best idea would be to allow them to set seed and re-sow next year.
Thanks everyone, they have now gone to the tip, decided its not worth keeping them, can sow more next year. Obviously this wet Summer really suited them to keep flowering into November.
If you like your sweetpeas why don't you get yourself the everlasting sweetpea that goes on year after year... I have one...It looks exactly the the normal one except that it comes back year after year... But is obviously more expensive...
