Sowing seed in ex-knotweed area
I know there are thousands of articles about this weed and I'm sure it gets a lot of coverage on these forums. But, I feel I have a specific question:
Is it ok to sow/grow grass seed on an area where knotweed has been?
A third of the lawn is grass, 2/3s soil. Knotweed was there, but was nuked by some specialists a year or so back. Would I be encouraging knotweed to come back by looking after that section of the garden?
Also, there is actually gradually some knotweed growing - very small so far on the massive soil patch. Could be dealt with separately from wanting to sow some grass seed?
Essentially: Will this section of lawn need to be eradicated again when knotweed comes up?
Just to say - I am a tenant in this place, not buying it! But all the same keen to get the lawn looking nice(r).
Any pointers much appreciated.
