permanent garden bed question

I started some permanent garden beds (mostly for veggies) last spring and now I want to renew them. Not sure what to add. Do you redo all the layers except the dirt and cardboard? Seems like I put down our local amendment mix, llama or rabbit manure, composted straw or woodchips and a layer of purchased compost.

My idea this year is to do manure and straw again (have lots of composted straw), plus the compost. Or can I get away with just some of those ingredients (for example, just compost)? Also, I am not sure whether to repeat with the amendments this year.

Some beds have potates and onions that I planted in the fall, so do I amend these now or wait til the beds are empty? I may end up interplanting somewhat so that would have to wait.

Hi,

I think the key thing is to mulch with weed free materials. This would include weed-free compost, salt marsh hay, quality straw (not hay). If you add weedy things like manure I would put another layer of cardboard then mulch on top with weed free stuff. Make sure you have some nitrogen rich material in there to keep the balance if you are using straw.
