In general, home-scale fruit and vegetable growers don’t pay enough attention to cover crops. That’s particularly true here in the deep South, where cover crops during the dormant season can make a crucial difference in the amount of soil organic matter and therefore in the soil’s fertility.
We’ve had much to say about sunn hemp, and for good reason. It’s hardy and reliable, and it’s the all-time champion when it comes to fixing nitrogen and adding organic matter quickly. But sunn hemp is a summer cover crop. What options do you have during the winter, during the months that are for most of us the “off” season? Lupin is a great choice there.
In our podcast today we describe our admittedly limited experience with this fun little legume, why we’re pleased with the results, and what we plan to do differently in future years. We finish with a brief conversation about whether you can eat the lupin beans.
