soil rehab post roundup
The fill dirt we purchased for two beds on our property was infested with nutgrass and bermuda grass (and a few other non-native weeds). After much research, angst, and self-flagellation, I sprayed roundup on the entire bed and am in process of removing as much of the plant and root as possible.
I called the local organic nursery and they recommeded I wait one year before planting anything edible in the bed. They recommended the following amendments - biozome, worm castings, compost tea, and a cover crop. I was concerned about the local wildlife eating the cover crop and ingesting any residual poison. I am considering a clover because that is only 4-6 inches and this bed is near my front door.
What do y'all think? I don't want to poison the bunnies... their second suggestion was to plant things that the rabbits would ignore like rosemary or sage, but refrain from using in food for a full year.
Once the soil is healthy again, I'd like to plan an edible landscape. The bed is about 8" raised with an eastern exposure and very large... about 25' long and 8-10' wide. The imported soil looks to be black clay from further east (we're in the edwards escarpment). The bed needs to be somewhat attractive because it is right at my front door.
Thanks so much for your suggestions!
(as an aside - the other bed that is also infested with bermuda that is now going to seed... I am living in fear that the bermuda will jump the bed and get out onto my property which, up until now, is strictly naitive plants. that bed is even larger and was already seeded with native wildflowers. i am clueless as to how to tackle that problem. this bed covers my septic tanks, so is really shallow in some spots and quite steep.)
