In fall I planted hairy vetch, a cover crop for my vegetable garden. This spring, do I just turn over the hairy vetch plant back into the garden soil?
Yes, this is the best way to get the nutrients back out of your cover crop.
I have a slip at my house and I would like to know how to soy crown vetch on a steep slope and have it stick to the ground, instead of the crown vetch rolling to the bottom of the hill?
Try something like a straw blanket with netting. Here is an example: https://www.lowes.com/pd/Hanes-Geo-Components-112-5-ft-x-96-in-Straw-Biodegradable-Single-Net-Blanket/3316406
Check your state for rules on planting crown vetch. It is an invasive species and some states list it as restricted. https://plants.usda.gov/factsheet/pdf/fs_cova2.pdf
I live in southern Wisconsin and have decided to try to save the seed from this summer's Hairy Vetch. Unfortunately I did not put them in a sealed container immediately after I "shelled" the seed from the pods. I thought they might need drying out before I sealed them in a bottle. I have more little black beetles (which look very much like the seed - great camouflage) every day so I am guessing they are being "born" out of the seeds because many of the seeds not have a perfectly round little hole in them. Should I put them in the refrigerator or the freezer for a while in order to kill the bugs? I appreciate any assistance you may be able to render unto me, marylee kishel
They may be infected with the bugs already. If this is the case, then there is no likely solution but to start with new seed. If left in ground, they will usually self seed, and you can dig up an established plant to transplant. This will be a more reliable way to propagate this, unless you just have plenty of already stored seed.
Insect infestation is common, and may not be noticed until it is too late. Putting in the refrigerator can reduce the number of living insects, but they may have already done damage by this point.

Hi I planted my rye winter vetch quite late (17th November) very very little has come up. Should I leave the beds free for germination in January or cover the beds? Thanks
Your question doesn't show your planting zone or your purpose for the cover crop, but if you think it will continue to germinate, I would wait for that. It would need to be turned under when it is between 6 to 12 inches tall for use as green manure.
Hot tap water is hot enough. Here's an article about soaking seeds:
I want to kill weeds and grass, not the crown vetch, will Pendulum work for that?
I looked at the product label and didn't see it listed as a safe groundcover to use it around. It suggests spraying it around a few plants and see how they react, before using it widespread.
