This is simply an addendum to my previous message, correcting the spelling of SEED.
Is there a way to edit an entry after it's been posted?

To add something what you've already posted if you'll change something in the 'Subject of Posting' it will allow you to post again right away.
Leave the seed pods on the plant until they're brown. If it's a seed pod that will burst when dry, you could tie a small cotton type bag around the pod to catch the seeds.
