It looks like it may finally be time to harvest those tatties. Jim is in the veg plot answering the age-old question, how do you know when they are ready for harvesting? Carole shows us two ways to plant up Alpine troughs.

Jim also takes a trip down to Logan Botanic Garden which is situated at the south-western tip of Scotland. It is the country's most exotic garden and is famed for its tender collections.
