After sowing, cover the seeds with a thin layer of soil. Each wrinkled beet “seed” is actually a cluster of 2 to 4 seeds, so you will need to thin the young plants to 3 to 4 inches apart once the greens get to be about 4 inches tall. This allows their roots to grow to their proper size.

When should I thin out beetroot seedlings?

ANSWER: You can thin beet seedlings when they are three inches tall. Cut down the entire portion of the seedling that is above the ground.

What happens if you don't thin beetroot?

They'll soon pick up, or new growth will take over as long as you keep the seedlings regularly watered. If you don't have enough thinnings to even out the row, sow extra seeds in the gaps. The beauty of using thinnings and resowing is that your harvest will then become staggered, rather than a simultaneous beety glut.
