In the Deep South, the garden year is entirely different from what most of us are familiar with. My second cover-crop experimenter, Sara, gardens in zone 8 along the gulf coast of Louisiana, and she was able to grow what I think of as summer cover crops in October, November, and December of 2014.

I sent Sara several different types of seeds to play with, but the only ones that sprouted and grew were oilseed radishes, buckwheat, and sunflowers. That last didn't make the cut as a cover crop due to excessive seed predation (the reason we now start our sunflower seedlings inside), but they did manage to keep growing until a hard freeze hit in early January. Buckwheat wasn't quite so hardy, but the plants managed to suppress weeds until the first light frost at the beginning of November.

Oilseed radishes are more of a traditional winter cover crop and in previous years, Sara has really enjoyed the amount of biomass the radishes produced in her forest garden. Unfortunately, during the study period the plants didn't do as well in her main garden, probably due to late planting (October 10).
