Chamomile Planting

So I plan on planting 1 acre of chamomile by direct seeding. I'm thinking about just spreading it by hand but  I'm curious how do other farmers usually spread the seed?

chamomile seeds are so tiny, it may help to mix with something else that’s kind of granular (sand, etc). i’d imagine there’s a real risk of seeding unevenly. i’ve grown a fair amount of chamomile, but i usually plant early and pot up before planting out. i can see why you wouldn’t want to do that at acre-scale! i do wonder if the tiny direct-seeded seedlings will be able to compete with weeds.

I use chamomile on paths. I order bulk organic  chamomile tea by the pound from Amazon, way, cheaper than buying seed packets. I hand broadcast on windless days, but since I am just covering paths, I can be a bit carefree.

The weed competition thing is the real challenge at that scale. Chamomile seedlings are tiny, anything else growing nearby just swamps them. Sand mix for spreading makes sense though, otherwise you end up with clumps in some spots and nothing in others.

I have no idea about farm scale, but chamomile once it's established is a force to be reconnected with. I planted some seed in one of my raised beds last year. It really took over the space. This year I didn't plant chamomile, and it's more dense than last year, and there are little plants all over the place. Which I'm not mad at. I can think of worse weeds.
This probably doesn't help much. I think if you can give it a relatively weed free space to start, it will be fine.  Good luck.
