Cover crops are a good practice for gardeners to adopt. They can build your soil health, add nutrients to your soil, and can increase your soils ability to manage water. The question however that every gardener needs to ask is what do they want out of their cover crop. Cover crops are not equal so you need to decide what benefits you want from the cover crop and then weigh out the good and the bad for the species that you choose.
There are negatives to cover crops i.e. weed potential, termination in the spring, planting date in the fall. For example, in a garden I do not recommend hairy vetch because if it can not be terminated in the spring due to weather conditions it can become a weed issue. Some cover crops that over winter can easily be terminated by tillage while others may need to be killed using herbicides. Also, correct planting in the fall is critical. Most of the cover crop species should be planted by early September. Winter cereal grains, cereal rye, wheat, triticale, winter barley, etc., however they will need to be terminated in the spring.

Christina Curell,
if you can plant within the next week, I recommend oats. Plant about 1.5lbs./1,000 sq. ft. They will winter kill and will help your soil. You can broadcast the seed and then lightly rake the area to make sure that you have a good seed to soil contact.
