Mustard and Turnips
This may not be fact… but this is what the “Old Timers” Say,
Just plow the garden and sling the seed. They will grow anywhere. Just make sure to keep an eye on them for the mites. You will see holes appear in the leaves. A light dusting of Sevin dust should kill them off. Wash good.
Farmers who differ widely about the proper dates for other crops are pretty well agreed that turnips should be planted on July 25, regardless of signs, weather, or the phases of the moon. Uncle Jack Short, of Galena, Missouri, quoted a little rhyme:
Sow your turnips the 25th of July,
You’ll make a crop, wet or dry,
and he tells me that this has been known and followed in his family for more than a hundred years.
