My husband used half a bag of concrete - cement, gravel and sand and
left the other half out, where it got wet. I now have a
half-a-plastic-bag-shaped lump of concrete. Does anyone know how I can
get moss or a similar stuff to grow on it, please? Or how I can age it
to make it look a bit more presentable. If it were green, it would be
quite attractive surrounded by plants but as it is at present, it is an
eyesore. Many thanks in advance.

I think you mix some cow muck with water in a bucket and paint it on.

Ah! There is a farm a couple of miles from here. Thanks, Martin.
