Similar to its relatives cabbage, broccoli and rutabagas, turnips are a cool season veggie.
They mature quickly so can be one of the first crops to harvest; and one of the last since they can take the cool fall temps.
These were planted at the end of July, as a succession crop when the potatoes were harvested. Of course we replenished the soil well first.
Here in the northeast area of the US, turnips, as well as a few other veggies, can be planted as late as September.
Turnips are pretty easy to grow, simply plant the seed about 1/2" deep and water. The seeds are tiny so if need be just thin a few plants to about 2" apart.
You can enjoy the greens in a salad or steamed, both from your thinnings as well as the mature veggie.
Don't you love it when you get more from a veggie?
They have a mild flavor and are wonderful added to mashed potatoes, in soups, or simply braised or roasted.
