Giovanna Fletcher has kept her tomatoes thriving despite the summer heatwave thanks to this clever watering system – 'it's like building LEGO'

One sunny afternoon in Richmond, I had the pleasure of sitting down with best-selling author, broadcaster and vegetable grower, Giovanna Fletcher, to chat all things gardening and water-saving tricks. I came away convinced that I need to try one irrigation system in particular: micro-drip watering.

Drip watering is an irrigation method that I’ve been keen to test for a while, and Giovanna told me it’s been a game-changer in her garden this year – particularly for her tomato plants. Giovanna is working with GARDENA in support of UNICEF’s WASH campaign, raising awareness about water scarcity across the globe (more than 2.1 billion people don’t have access to safely managed drinking water), and the importance of becoming more conscious about water usage. We really can make a difference in our own gardens here in the UK – it’s just about changing the way we hydrate our plants.
