The left side in this photo had our Squash and Pumpkins. I disk harrowed to cut the vines and broadcast in our Oat and Crimson clover cover crops here like the rest of the garden. Cut by the disk blades without clogging a cultivator or rototiller these vines will disintegrate some over the Winter and when I disk harrow the cover crop in the Spring all will enrich the soil for planting.
