On Tuesday, Ady, Graham and Callum began the task of replacing the gravel flooring in the cold frames to cement flooring. The reason behind this change is to try and prevent the build up of weed as they set seed and germinate in the gravel, see blog entry 13th August 2013 'Killing Weeds In The Cold Frames'.Two frames were successfully changed this week, the cement levelled at a slight downward gradient from back to front, allowing any water to run off down to the very small gravel soak away. Once set, Ali put one straight in to use by putting 230 wallflowers on to the new cement floor.
