Currently have two plots. One is a second year plot first year was brassicas, this year is clover which has done very well. The other plot (first year) is a brassica, oat and winter pea mix. The oats make up the majority of the plot followed by some small brassica and havent seen the winter peas. The area is more rocky then I would prefer but thats what I have. In all the plot has good coverage and the oats seem to still be growing, even after some significant snow last month. Should I alternate planting these plots with something else each year?
