Sounds like you are off to a great start for beet green salad! Harvest the green tops by pulling them right out of the ground when they are a few inches tall to thin the beets. Eat the young greens in salad or stir fry. If they are already taller than six inches or so you can dig up the root and snip off the tops any time over the next 3 to 4 weeks or when the underground root (the beet) is the size you prefer. Steam the leaves and roast the beets themselves or boil and use cold in salads - so delicious and yes, they really are very good for as veggies with dark colors are full of anti-oxidants. Keep growing, Marianne Binetti One more thing - you can plant a second beet crop after you harvest the first.
