How early to plant food plot?

[Blazed]

I had some great success with turnips this past fall in Sauk County. After Oct1 had deer on them every night/mornng I hunted. The plants did not get very tall before the first frost, or I think it would have atracted more, Usually, only 1-2 a hunt, and mostly doe. I planted Aug 5 last fall. I'm 
wondeing if I plant sooner, will I get bigger plants or bigger weed problems? The weeds were just starting to catch the turnips before snow, of course there wasn't much left of the turnips by then. I did not do a good job with weeds before planting though. I plan to do better against them this year.  
 
What date is the earliest you've planted turnips with success?
 
Also, any luck with chicory or buckwheat? When should these be planted?
 
Always looking to do better.

From what I've read, you planted in the right time frame.
Hopefully some others will have some better advice for you because I will be planting them as well this summer.

I've always heard to plant turnips middle of July, by the time season roles around they should be going pretty good.
