When do I collect nasturtium seeds?

I would wait until later, when the seed turns a brownish colour...collect them and keep them in an envelope or paper bag...then use them next spring...they are very easy.....

Alternatively if you want more nasturtiums i the same place next year just leave some of the seed to fall and do its own thing.

Thanks for that you 2...I'll do both.

I wouldn't worry too much Fluff - where nasturtiums have grown one year, they'll be returning for some years from self seeding!

That's good news Bamboo...one less thing to do next year then!

I have them popping up all over. As usual some of the positions are better than if I had planted them there.

what do i do with my nasturtium seeds from this years plants

The replies to my question here pretty much answers that one for you Tiddlewinks...keep them dry & cool in an envelope or something.
