Rye looks nice, but it's root structure doesn't do anything to hold the soil in place when it rains. The only way to slow down errosion is to slow down the water.
You always have good solid advice Eddie. I'm gonna slightly disagree with you on this one.
In fall you seed down the rye. There is typically less rain in the fall, and you are typically finishing up the groundwork.
The rye sprouts, grows a bit, goes dormant in winter, comes up green as one of the first plants in spring, and keeps growing. Fast. With any luck at all, it will outgrow the rains & get itself rooted well and hold the soil in place. It's the best chance of anything green to hold down the soil.
This is in a very cold frozen Minnesota climate anyhow. And I realize it doesn't fit this situation as we are past fall for this person.
But for others that come across this situation, planting rye in fall - even if it's too cold for anything else to sprout - is going to help out a whole lot, if not solve the problem, come next spring. It's good stuff 'here'.
I didn't follow my own advice - had a shed built, and it was way too cold. I sprinkled some oats around the site, told my wife it's a waste of time & $10 of oats! Well then we had a real nice warm November, and the oats grew an inch high. Darn it if that had been rye, it woulda been 2 inches high, and it would have been great results in spring! The oats will help me a bit, but will be dead & not very deep rooted to hold very much....
Rye is good stuff. I just need to listen to myself.
