Need advice on bringing zinnias in for seeds before frost
Thanks to the birds, I've collected very few zinnia seeds this year and now they're predicting frost for three nights this week. They're tall so I think it would just break them off if I try to cover them so I thought I might try bringing some in to hopefully finish. In hindsight, I should have netted some to keep the birds away but I didn't get around to it.
How successful do you think it would be if I just cut some and put them in a vase of water for awhile? Any advice?
