When plants get frosted the cell contents are lost, including sugars which contribute to digestibility.

“When only the top two leaves are burnt off by frost it is not too serious, but when there is a severe frost, harvest immediately.”

Remaining monitor sites will be harvested soon.

Gelli Aur College has increased in DM by 6%, but after a drop last week the average rise is just over 2% a week, he adds.

“Brian Metcalfe in Leyburn usually harvests between the 10 and 20 October and the crops are looking like they will fulfil this timetable.”
