I got an immediate reply on the next working day which was such a relief as I was worried that the plants were Japanese knotweed. An early reply put my mind at rest. And I gave pictures of several plants. It's comforting to know that the results are from a trusted source.

They emailed me back
They emailed me back, explaining what weed killer does to weeds. 🤣
And justifying that he’s sprayed weed killer at my car with no weed in sight.
This company is completely unprofessional, doesn’t care about there worker missing a road that the council have clearly paid for them to do.
We have so many weeds in sight on the pavement, this worker stayed roadside and just sprayed every car.
Weed killer isn’t meant to be sprayed on Metal or car tyres. Guessing that wasn’t part of there training, so why nothing is being done about this Man. It’s criminal Damage, my opinion is straight dismissal, I watched him do the whole road purposely. Up and down within a Min and pissed off every neighbour. I wasn’t risking it so got car cleaned straight away.
Where online does it say it’s okay to put weed killer with chemicals on car paintwork.

Brilliant FREE Service.
Brilliant.
Had concerns over a plant in next doors garden which I thought could be Japanese Knotweed.
I sent two photos to this company & asked if they could advise.
They responded within half an hour & confirmed that it was NOT the dreaded Japanese Knotweed.
They even took the trouble to suggest what the plant in photos was.
Excellent FREE service & their advice has put my mind at ease.
Would recommend to anyone that has concerns regarding Japanese Knotweed.
