I think you meant that it was 12:44 AM.* I had to go to sleep as the thunderstorm stopped and the dogs calmed down.
Those sites about cover crops are a bit complicated, especially the first one.* Planting something like winter rye or oats in the fall will keep the soil from blowing away or being washed away in the winter and keep alot of weeds from growing.* The roots will hold the soil together and the top growth will protect the top of the soil from the wind and rain.* In the spring you dig it up, turn it over with the green growth now on top of the soil and break it up into smaller chunks.* That way it can decompose and enrich the soil where it grew.* It takes about 3 weeks to for this to happen.* Then you can plant.* The last site I gave you explains it about half way down the page.
When weeding, the best way to make sure you are removing a weed and not a valuable plant is to pull on it. If it comes out of the ground easily, it is a valuable plant.
