I'm a total gardening rube, so this will be a Stupid Question.
I've had the most amazing display of sweet peas, but didn't realise that leaving them to run to seed was disastrous. I am now left with a few flowers and festoons of seed pods.
Is it now just too late to do anything to encourage more flowers? What do I do - cut them right back and give up for the rest of the summer? I don't even know whether sweet peas will come back next year or should just be dug out...
Thanks!
