What does thinning Kohlrabi mean?

Question

i planted them from seeds but they don't look like they should. Do I have to plant them deeper? They would be about 6 inches tall right now but they lay flat in the garden. Also how deep do radishes need to be - some of the red is showing, is that normal?

Answer 1

if the red shows, it normally means that they are ready, or nearly ready, to be harvested.
