Nemesia and night scented stock

Hi,
I planted the above and have had lots of lovely flowers, however both are now looking a bit leggy and tired.
Can they be cut back to reflower?
the night sented stock particularly seems to be well past it's best, is there a way to get it going again or is it time to clear out and wait for next year.

Both are in pots and fed weekly with phostrogen dissolved in rainwater.

Thanks
D

 

You can take off all the dead heads with a trim on the Nemesia. I haven't grown them for a while but I found it makes them 'bounce back' with a new flush of flowers.

Sorry, not sure about the stocks. I would have thought not.

 

The night scented stocks are one hit wonders. You can get rid of them if they're looking tired, as they won't regenerate. You can extend the flowering season of your stocks by sowing seed in batches rather than all at once, so that later sowings replace the earlier ones.

 

Thanks guys
