the seaweed, kelp, and shells are ready to mix into the newly workable soils along with plenty of poultry manure, compost, and gypsum...you can still see the remaining kale...we covered their roots with a little extra soil and straw (from the tundra/beach, no seed heads!) and cover them loosely when there is a danger of a heavy frost....last day of Februrary and so far so good....they are very hearty plants, one just has to keep up with them so they don't bolt...which is exactly what they are going to do when they start growing more in a month or so yet, it has and will provide us with greens until things get going this spring...
