A few years ago I had the front of my home cemented. I told the workers
to leave a 3' x 3' opening for a possible shrub planting. Since then,
every time I tried to plant something in that 'plot', the plant would
die. i suspected a gas leak...but the gas company disproved that
theory. Now, I want to patch up that opening. As of now, it has a low
layer of red mulch on top of the soil that was originally there. I
bought a bag of quickcement, Is there any thing I should know on how to
go about this and trying to match the rest of the cement? Some neighbor
suggested a crossironbar. I think its called. I've seen that being done
whenever I pass a large mason job on some sidewalks...but others say
its not necessary for the little spot that I have. Suggestions?

----------------------------
New concrete will not "seal" with the old one, hence is the possibility
of water seeping in between. If water freezes, it will expand and
could cause damage to the new concrete (or the existing one)--uneven
expansion will also occur in extreme high tempratures. Here is what I
would do: (1) Dig the 3'x3' area until you reach stable soil--at least
the 3-1/2 inch thicnkess of the slab. (2) Lay a grid wire in the
bottom (or rebars--but this is an overkill). (3) Place (tar-based)
exapansion joints on all four sides. (4) Pour concrete. On the other
hand, if extreme tempratures are not an issue in you area, then you may
use step 1 followed by step 4.

Well a good soil test would tell you what the problem with the plants
is. I suspect the soil is too alkali.

If you want to fill it in, the first question is will it be subject to
vehicle traffic? Totally different needs for that.

One bag of concrete mix (not cement) is not going to cover 3x3 foot
unless it is one mighty big bag. :-)

The concrete will make the soil alkali, correct?

Probably, the easy fix is vinegar, I pour some around my pine trees and
they get so green it almost black. We are in an area with limestone as
a base, alkalinity rules. I use a lot of acidy stuff to balance it out,
but it wins in the end. The O.P. likely has a "caused" problem, much
easier to fix.
