Ten years ago, Kate set about saving her little farm from being sold off. Now she's hunting for innovative methods to make her it profitable, visiting farms across the UK in search of inspiration.

Kate wants to maximise the returns from her cattle herd, and learns about the prize-winning cattle that command the best prices. Plus she renews the fencing at the farm's northern edge.

Kate focuses on her flock of 300 sheep. Their fleeces can fetch as little as 60p each at today's prices, so she's determined to see if she can find a more profitable way to sell her wool.

Kate embraces treehouse accommodation, and arrives after a shopping trip with three tiny additions to the farm. She also explores a dark secret beneath the surface of the River Wye.

Worried by the damage wild deer cause her trees, Kate travels to the Highlands to see how they manage the animals. Plus the farm goes into business with a restaurant.

Kate visits an innovative tea plantation in Wales - but does its business model stack up? Farmer Tim is off to market with his yearling cattle. What price will he get?

Kate visits a farm to explore the use of solar energy, heads to Wales to look at beautiful sea eagles, and, in her outdoor kitchen, grills meat skewers with flatbreads.
