new asparagus bed and mulching
We started a new asparagus bed this year but didn't give it as much attention as we should have. Here it is the end of October and we finally got the bed weed but still haven't filled in the trenches as much as the books recommended.
This year I also planted in a lasagna bed for the first time after starting it in summer '07 while we were moving and renovating the house. The bed did wonderful but next year I won't plant so densely.
Would it be ok to put a layer of newspaper between the rows of asparagus and then mulch/sheet compost on top of them? We have a pile of rocky soil to re-fill the trenches but after weed and rock removal there won't be enough soil to bring trench up to grade level. I still have a pile of grass clippings (big yard). Should be able to get more leaves. How many inches of each should I layer? Is too much going to smother or burn the roots? I'm also in search of manure and hope this would be the top layer. Would I be foolish to put horse manure on the bed? I keep hearing it has too many weed seeds.
