Strawberries, anyone?

Along the banks of the River Tay, Scotland's strawberry fields are gearing up for an early crop.

This area has always been famed for its soft fruit, but the season now is vastly expanded by the use of polytunnels and horticultural fleece. In my childhood strawberries didn't appear until the end of June. My father always used to visit the Royal Highland Show in Edinburgh around the 23rd of June (he was a grain merchant, and this was - and is - the main social gathering of the farming world). He would return with a couple of punnets of precious early strawberries, at least a week before our northern berries in Moray were ripe.
Below, the tunnel doors are closed to increase the heat. I think the plants in these tunnels are growing in raised beds, to make picking easier. Meantime my own plants at the allotment are sitting thinking about putting forth a few new leaves. We'll be having traditionally-timed strawberries in June.
