Tonight's programme looks at how south coast grower Barfoots has become a major producer of the once exotic crops of sweetcorn and chillies, and visits Essex grower and specialist jam maker Wilkin & Sons of Tiptree.
Tomorrow's episode features the UK's northern-most blueberry grower, and looks at why Scotland's seed potatoes sell all over the globe.
The final episode on Thursday visits Thatchers cider, a mushroom grower and an aquaponics grower in Somerset, and a large scale quinoa grower in Shropshire.
All three episodes are shown on BBC Two from 8pm.
Shown two years ago in a similar format, Harvest 2013 was generally welcomed by the fresh produce industry for raising its profile among the shopping public.
