Gardening - Turnips
Full sun, moist, and well draining soil are the prime location for your
turnip seeds to be planted. You should fertilize just before you plant
and then once the plants are up and you are thinning out the areas
that need thinning.  If you are planting turnips for the greens,
remember that the younger plants have better tasting greens than
older plants.  I wouldn't let my turnips get bigger than two and half
inches in diameter before I picked them.
