John Craven and the Countryfile Diaries team - Keeley Donovan, Jules Hudson Paul Martin and Margherita Taylor - report on interesting stories of the season. Today, Margherita visits Devon's first commercial tea plantation to discover why the UK could have the ideal environment to grow tea, and finds out how to make clotted cream to go with it. In Kent, Keeley investigates what an earlier spring could mean for the countryside. Jules is in Jersey to find out how golf is helping to protect some of the country's most endangered species. And Paul reveals that feeding bread to ducks could be doing them more harm than good.
