I could use some advice on Sakrete cement slab. When I make a
slab, I
usually let it cure for several months (even a year) before
using. However,
I need to use a slab that was just made about three weeks ago.
I have been
washing it daily and buried it a few days ago under wet mulch.
It will be
used on the 1st of July. My question is: Is there anyway I can
lessen the
possible damage to trees planted on the slab or change the pH?
Thanks,
Julie


1. I wouldn't worry about it; your trees' roots won't be getting
down to the slab itself for a while, and its effects on soil pH
will be minimal at best anyway.

2. But if you insist upon worrying, put a lot of sphagnum in the
soil mix.
