It's every gardener's dream — weed-free growing! In this episode, George Anderson and Calum Clunie help cut down on those unwanted plant pests. The pair select varieties that provide great ground cover as they grow, and that ground cover will help limit the spread of weeds in future seasons. Calum takes on the next stage of developing his hot be. A few weeks ago, he built the frame and filled it with organic matter that will be a natural source of heat, and this week he plants winter veg that will keep growing as the autumn temperatures drop. Calum also provides the last update of the season from his cut flower bed to find out what new blooms have appeared now that we are more than halfway through September. Plus the latest from Brian Cunningham at Old Scone.
