At great expense we have had our lawn returfed, it having been
destroyed by the builders last year. It's looking pretty good, but
there are two problems.

1. It has weird patches, mainly circular about a foot in diameter, of
much lusher, darker green grass. When it was laid all the turves, so
far as I could tell, were identical. The turf came from a very
reputable supplier. Has anyone got any explanations?

Do you have a bitch (in the female dog sense of the word)? If so, bitch
urine will do this

No it won't. Bitch urine leaves brown patches.

Brown (or yellow, or totally bald) patches in the middle, but the grass
grows like crazy around the outside - it's basically good fertiliser
for grass, but can be so strong that it kills the grass where it hits.
Dog dogs don't seem to cause this problem as they tend to spray it
around more and up trees and things, whereas the bitch squats and
squirts it all in one place.

It probably also depends on the size fo the dog and the amount of pee.
I would imagine the amount from a small dog might not be enough to kill
the grass but just fertilise it. I think it also depends on the
concetration of the urine (i.e. its worse with the first pee of the
morning), and the weather conditions - if its wet and rainy, the pee
gets diluted before it can kill the grass.....


Anyway - enough about dog wee.
