I do the same thing with the seeds because it's hard to tell a weed from a seedling. Mostly because there isn't much difference. Even weeds can be seedlings. The bastards! LOL.
I wouldn't worry about the borage, just keep your eyes open for them when you see seeds for sale anywhere. Even if you have to keep them until next year...most of them will still grow.
I haven't done the dill, and I hadn't done the borage for about 4 years, but each type helps, and the more the better. If you got every one but borage, you're doing great!
Some of the most successful and creative people I’ve ever known seem to be unacquainted w/the “rules.” I’ve learned to attend to the matter rather than the manner. Laissez le bon temps roulez! (Sp?)
