RE: planting turnips?
I am going toplant "purple top" turnips for the first timethis year for a late season plot. I have heard a lot of good things about them. Your best bet is to look at your local seed and feed/ farm and garden store. You can get them at places like Gurneys, but I'd imagine your local seed and feed store will have cheaper prices per pound.
I have a thread asking questions about turnips, its probably on one of the next few pages ofthreads...it was a few weeks ago. Igot a lot of good info from forum memberson seedbed prep, types of brassicas, etc.., it may help you.
Good luck, have fun.
