Planting beetroot you need to soak them first

One of the keys to growing beetroot from seed is to soak the seeds in warm water first. Warm not boiling.

If you want to know which beets are which you'll need to keep track of your soaking seeds.  I put a few seeds in small bowls and tuck the seed packet underneath until I am ready to plant.  Stagger your plantings and your harvest by planting every two weeks.
