Dad farmed for 50 years so he does has some experience planting stuff, including turnips. When I mentioned this idea he had some saying about "wet or dry plant turnips July 25". Anything to that?
I'd say your Dad knows what he's talking about
I hope to check my main plot in the next week or so. I've tried to stay out of it during hunting season, but they had been killing it since September.
The pic below...they have not touched but it is surrounded by alfalfa, rye and oats and it remains to be seen if they will eat this patch later in the winter.
Availabilityof other food sources and the "safety" of the plot (is it hidden) has a lot to do with it.
Often it appears that deer may need to "learn" to like brassicas which might take several seasons.
I can tell you that oats and rye next to a blind will be irresistible no matter how much other feed is available.
These deer are scarcely 10 yards from my blind eating oats that are very nearly frozen off now.
Note in the foreground it is bare...I had brassicas there but several weeks of extreme dry weather and heat killed them on this hillside.
They do much better on moist soils with higher PH.
Whenever possible plant several items in case one fails, or deer prefer one over another.
A blind is an excellent place to observe what they like...just be fore you put em in the freezer
