Carrot seed packet says "sow thinly".
Numbers needed!
1 per inch?
4 per inch?
8 per inch?
Or what?

Depends on how old your seed is and what pests you're having trouble with.
I sowed thinly, in cardboard tubes, and 3 out of about 200 came up. Then
I sowed thickerly (!) and I started getting about 1" coming through which
was about a 5% success rate, and then something came along and munched
through the lot.
Stupid carrots. :-(
