I am not familiar with this term.... if you mean pelleted seed then in the long run its cheaper since the seed prepared this way are very small & you would have all the seed in one small location & not in a larger area.....

From what I can tell, it is a similar method to pelletized seeds. The question I have, though, is about volume. If I put all of my hollyhock seeds in one seedball, wouldn't that make for too much density? I'll attach a link for seedballs below. Thanks for your answer!

OT, just an aside should one be interested, have seen seedballs much as described in the link above used in reforestation projects, dropped from a helicopter in areas otherwise quite difficult to access.

They really are amazing, aren't they?

Funny you should mention this topic. One of the articles in DG newsletter this week, talks about making seedballs.
Here's the link.

Thanks for the link, Theresa.

I'm guessing using less seeds in seed balls and therefore planting with more precision is not an option, based on the lack of responses about that. Ah well!
