I am planning on putting in some asparagus this year and have a bunch of questions. I have an area of about 10'x10' that is gets a lot of sun. There used to be a bunch of shrubs there that I cut out over the last couple of years. I'd like to run my single bottom plow through it to break up the soil and let me get whatever roots are still left out. How many asparagus roots can I put in that area? I haven't tested the soil in that area but in other places nearby where I plant veggies the ph is about 6.8-6.9. Can I use peat moss to help acidify the soil? We have a problem with LOTS of rabbits. Will I need to fence this off? Does anyone have a recomendation on the kind of root to get? We are in Vermont, zone 4. Gurney's is having a sale that ends on May 17 so I'll need to put my order in soon.

Thanks for the help.
