Amending Stump Grindings With Biosolids - March 2023

Spring seems like the season of biosolids-application posts and today is no different.  Last week, I posted a series of photos showing my use of biosolids in the parkway.  And, then I talked about how I was going to use biosolids in a vertical-mulching application to try to help remedy by clay soil problem by our front porch.  In that post, I referenced how I added organic material to the stump grindings to help the Triumph Elm tree thrive.  

As another step towards helping these stump grindings  breakdown, I threw five gallons of biosolids on top of them - right next to the new tree - where some tulips are coming up.  You can see that in the photo below.  I didn't work them in the ground, but, as I keep up with the 'vertical mulching', I'll likely add even more surface biosolids like this batch below.

The combination of organic material (and nitrogen) are going to be critical to making this bed a desirable place for plants and shrubs in 2023.  At least....that's what I am (currently) believing is the path to viability.
