I have just seeded a large lawn just out side Cambridge , and have been
swamped with a weed that I need to eradicate .
It grows very quickly and can form a hummock in 3/4 weeks , it has Geranium
type leaves and flowers bluish .
The area that the lawn is in ,has been the corner of a neglected farm field
, I applied Roundup on 3 occasions before seeding ,
but the amount of weed seed must be tremendous . I aim to give a diluted
dose of selective this autumn , and some more when established .
I,m from the north east and have not encountered this one before , i,m
curious , and do not want to appear dumb asking the locals .
Thanks all for previous answers .

Mike
