My partner and I exited the A47 at Thorney and drove via back roads to Wisbech.

I was astounded by the amount of Ragwort growing in fields where horses were grazing.

Do the owners not realise that ragwort – in its dried state – is toxic to horses? Or do they not care?

I believe that death is lingering and painful and although horses are not prone to eating it, responsible horse owners ensure every last root is removed from the field.

One concern is the fact that its prevalence is on the increase. It grows quite tall, has ‘frond-like’ leaves and yellow flowers.

Please can you bring this to the attention of horse owners in your area?
