Front Porch Bed - Cardboard to Smother Grass + Top Soil + Biosolids - March 2024

Just a week ago, I spotted some issues in the corner of our front porch bed.  It is a low-spot and because of that was taking on some water from the downspouts.  But, the front part of that bed was also showing some signs of turf coming back.  This was a small extension that I carved out of the lawn last year.  And...it turns out...I must not have pulled out/dug out all of the turf.  

I decided to kill-two-birds in this project.  (Well...half of a project since I didn't have enough materials to finish it.)

First, I laid down some cardboard to smother the grass.  I cut holes for the handful of tulips in the area, then spread out some thick, unpainted cardboard on top of the turf.  I then went back to the pile of topsoil and clay that I excavated from the Pizza Oven foundation and spread that on top of the cardboard.  

I started by the property-line edge and went north.  Below are a few photos showing the progress - first with the cardboard and topsoil + clay.  

I initially only did a few linear feet.  But thanks to the good guys at Amazon, I was able to get a little more cardboard.  

I ended up being able to cover about half of the 'berm'd bed' from the property line-in with cardboard and topsoil/clay.  See below:

I then went and grabbed a couple 5-gallon buckets of biosolids and top-dressed the native topsoil with biosolids creating a thicker layer on top of the cardboard.  See below for the final product featuring topsoil, clay and biosolids.  

I have about six-or-seven more linear feet to do in this bed.  Once I get enough cardboard, I'll get the rest done.
