help with planting dates for fall/winter cover crops in northeast
i just started a half acre vegetable garden this year that has low soil fertility and was compacted by heavy construction equipment. Growth was poor, but i now have an opportunity to plant some fall/winter cover crops that will hopefully help improve the soil. i'd like to plant oats and field peas together in one block and oilseed radish in another. In zone 6 CT, when should i plant these? i was thinking of seeding the oats first, maybe in August, and the peas and radish in September. i'd like them to winter kill so that i can plant some spring vegetables next year. How many days before first frost should these go in? Thanks for the help.
