how to cut sweet peas to stop them setting seed?
I have read that you should cut them every few days to stop them forming seed and keep them flowering, but does this mean trim the whole stems or cut off the individual blossoms (and not the stem)?
If you do cut the stem, do you cut it right at the join with the plant or further away? And will you get more stems after that?
Or do you dead-head them like other flowers, just behind the bloom?
